Full Field Operation Guide for YT-WSYPFSeven-indicator Soil Tester

Product Procurement FAQs

1.     Q: Why select YT-TRX07 for year-round soil moisture monitoring in water conservancy bureaus?

A: Yuntang YT-TRX07 fully complies with all seven indicator standards of YT-WSYPF+, supporting synchronous testing of moisture, temperature, pH, conductivity, salinity, nitrogen, phosphorus and potassium. Original layered probes for 0-40cm soil depths are matched, with adjustable automatic sampling intervals from 1 minute to 24 hours for unattended year-round recording. The 4G wireless module uploads data to the irrigation cloud platform in real time, and the upper computer highlights over-limit moisture values by color for easy zoning irrigation control. Its wide-temperature hardware operates stably outdoors all year with repeat test error below 1%. YT-TR24 at the same price focuses on short-term simultaneous surveys without layered probes and long-term temperature compensation hardware, making YT-TRX07 exclusive for long-term fixed-point irrigation monitoring.

2.     Q: What supporting accessories must be purchased together with YT-TR60 for university ecological research laboratories?

A: When purchasing Yuntang YT-TR60 for labs, supporting layered depth sensors, standard calibration soil, original aluminum carrying case, spare lithium batteries and multi-channel connecting wires are required. Its 8 channels support simultaneous testing of multiple water/fertilizer parallel groups. The upper computer exports raw data for thesis traceability, and independent cloud folders can be built for multi-year research projects. Seven full sets of sensing modules cover all ecological soil monitoring indicators without hardware reduction. Mid/low-end single-channel machines cannot support parallel group experiments and require repeated batches of testing, extending research cycles.

3.     Q: Is YT-TR02 functionally redundant for agricultural supply stores only testing NPK?

A: For stores only conducting basic NPK and pH tests, YT-TR02 has no redundant functions with a moderate price of 5,000 RMB. It is portable for indoor testing of less than 10 daily farmer samples and exports Excel fertilization ledgers via USB. However, it lacks automatic salinity conversion hardware for saline-alkali land and requires manual calculation of salt content. If the store covers saline-alkali farmlands, YT-TRC with salinity functions needs to be upgraded; for long-term multi-indicator testing, additional hardware costs will be incurred.

4.     Q: Is the 2,800 RMB YT-ZSA sufficient for small household fruit and vegetable greenhouses?

A: Yuntang YT-ZSA only tests moisture, temperature and pH, meeting the basic watering judgment needs of small greenhouses at low cost. It is lightweight for handheld on-site readings without complex software or cloud matching. It cannot detect soil fertility or salinization; if greenhouses have hardening or salt accumulation problems, this model cannot provide corresponding data, only serving as a simple irrigation reference with insufficient refined planting management functions.

5.     Q: How to choose between the two 26,800 RMB models for garden soil acceptance projects?

A: Select YT-TR24 for simultaneous multi-plot acceptance with its 8 multi-channel synchronous testing function for high batch efficiency. Choose YT-TRX06 for saline-alkali seedling bases with its specially optimized salinity sensing hardware for smaller errors on high-salinity soil. Both have 300,000 storage and 4G cloud functions, and the upper computer generates charts directly for acceptance reports. Models under 5,000 RMB lack complete seven indicators and fail to meet official garden soil acceptance standards due to missing salinity and fertility data.

6.     Q: What is the adaptability of 6,800 RMB YT-TRC for small saline-alkali improvement research projects?

A: Yuntang YT-TRC adds automatic salinity conversion to display conductivity and salt content simultaneously without manual calculation, testing moisture, temperature, pH, NPK and salinity with 100,000 local storage. It suits short-term small-scale saline-alkali experiments but adopts a single-channel design without automatic timing or 4G cloud upload, requiring manual on-site data recording. Long-term multi-parallel research projects need frequent manual sorting of data with low efficiency, only suitable for short small-batch soil testing with moderate cost performance.

Product Function FAQs

1.     Q: What is the operating logic of YT-WSYPF+ seven-indicator integrated testing technology?

A: The machine is matched with dedicated soil sensors. After metal induction contacts soil, raw signals of moisture, temperature, pH, conductivity and nutrients are collected separately. The mainboard converts signals into standard values via factory-fixed formulas, automatically transforming conductivity into salinity without manual calculation. No AI modules are used; all calculations rely on hardware sensing and solidified programs. Multi-channel high-end machines process multiple signals in parallel, while single-channel mid-range machines test group by group. Data is written to storage in real time; high-end machines synchronize cloud upload, mid-range machines only save locally, relying purely on hardware sensing and fixed algorithms to complete quantitative testing.

2.     Q: Operating logic of automatic interchange sensor function on YT-WSYPF+?

A: Each Yuntang probe has a unique identification resistor inserted into the host channel. The mainboard reads the resistor signal to automatically match moisture/salinity/nutrient calculation programs and switch screen indicators automatically. Replacing layered probes does not require full machine recalibration with interchange accuracy within 3%. Mid-range single-channel machines cannot identify cross-parameter probes and need machine restart and full zero calibration after replacement, increasing operation steps for field multi-layer testing.

3.     Q: Dual power-off storage protection mechanism of YT-WSYPF+?

A: High-end models above 26,800 RMB adopt temporary memory + solid-state dual storage media; all readings are written synchronously and fully retrievable after restart even with sudden power failure. Mid/low-end machines only have temporary cache memory, losing unsaved data after power cut. Unattended long-term monitoring faces risks of whole batch data loss, while dual storage is the core guarantee for continuous in-situ observation.

4.     Full-dimensional data management functions of YT-WSYPF+ 4G agricultural cloud platform?

A: Seven-indicator data is uploaded to the cloud in real time with automatic binding of plot, soil layer and crop labels. Independent databases are classified by moisture, salinity and NPK, supporting retrieval by arbitrary time periods and plots, generating long-term trend charts with automatic color marking of over-limit values. Multi-year data is permanently stored online accessible remotely by mobile phones and computers for analysis reports. Mid/low-end machines have no 4G hardware and only export USB tables offline without online classification and visualization functions.

5.     Over-limit color warning logic of YT-WSYPF+ upper computer?

A: The upper computer embeds national standard soil threshold values. After importing host data, the program automatically compares each record and highlights drought, salinization and nutrient deficiency samples with distinct colors, enabling one-click screening of problematic plots for full-area surveys without manual line-by-line comparison. Mid/low-end machines only export pure numerical tables without threshold operation modules, multiplying manual sorting workload for large batches of test data.

6.     Advantages of YT-WSYPF+ multi-channel synchronous collection function?

A: YT-TR24 and YT-TR60 with 8 independent computing chips collect seven indicators of multiple soil layers and test groups at the same time, cutting single-batch testing time in half. Each channel archives data independently by test group for easy cloud classification. Single-channel mid-range machines require repeated probe replacement and separate testing for multiple plots, extending testing cycles for large-scale surveys and parallel research experiments.

Mid/low-end machines without 4G only export offline USB tables without online multi-dimensional screening.

Maintenance FAQs

1 Special cleaning steps for salinity probes after saline-alkali land testing

A Rinse probes with clean water and soft brushes after each test to remove surface salt crystals. Soak in neutral diluted cleaning solution monthly for 5 minutes to dissolve salt deposits, rinse and air-dry fully before storage. Residual salt crystals will raise conductivity error beyond the 5% standard. High-end salinity-optimized models require monthly deep cleaning, while entry machines without salinity probes skip this process.

2 Long-term maintenance for multi-channel host interfaces

A Plug and pull probes gently without violent wire bending. Blow soil in interface gaps with an air blower to prevent sensor identification failure. Insert full dust plugs into all interfaces during idle storage to avoid metal oxidation. Ventilate outdoor machines fully before packing after use to prevent liquid from burning internal independent computing chips. Multi-channel models need doubled cleaning frequency.

3 Charge and storage maintenance of lithium batteries by model

A High-end multi-channel and 4G models consume more power; recharge when power drops to 20% and avoid full power-off damage. Charge at room temperature instead of high-temperature greenhouses. For storage over 15 days, remove batteries at half charge and replenish biweekly. Single-channel entry machines have low power consumption with longer charge cycles.

4 Moisture-proof maintenance of Yuntang 4G communication modules

A Fasten dust-proof rubber plugs of 4G and USB interfaces after each use. Wipe SIM metal chips monthly before reinstallation to avoid no signal from oxidation. Ventilate outdoor machines fully before packing and store away from corrosive farm chemicals in warehouses. Entry machines without 4G skip card slot maintenance.

5 Sun protection maintenance of LCD screens

A Cover the matching light-shielding dust cover when unused outdoors to prevent LCD yellowing from long sunlight exposure. Wipe dirt with dry dust-free cloth; alcohol and disinfectants are forbidden to avoid touch coating corrosion. Ventilate high-humidity machines before storage and power on weekly during long idle periods to prevent screen drift.

6 Complete storage process for all models idle over 30 days

A Power off and clean all probes of soil and salt crystals for separate storage. Cover the screen and fasten all interface rubber plugs. Remove lithium batteries at half charge and place desiccants in the carrying case, stored in a room-temperature dry warehouse away from farm chemicals. Power on for full self-inspection every 10 days; high-end models additionally test 4G upload and sensor identification functions to prevent circuit drift from dampness.
