Product Selection Questions

1.     Q: Selection for detection of paddy field crops?

A: Paddy fields have high humidity and dew, prioritizing moisture resistance. The Yuntang YT-YC operates stably in high humidity with non-destructive design suitable for rice leaves. Multi-parameter detection guides fertilization. Lanhong has poor moisture resistance. Zhongyun’s screen easily fails in dew. Yunze is unsuitable for long-term paddy use. Yuntang YT-YC is preferred for major rice producing areas.

2.     Q: Selection priorities for dry farmland crop detection?

A: Dry farmland has strong light and large temperature differences, prioritizing anti-glare, wide temperature range and battery life. The Yuntang YT-YC adapts perfectly with rapid measurement improving census efficiency. Lanhong has low efficiency. Zhongyun performs poorly at low temperatures. Yunze has insufficient overall performance. Yuntang YT-YC is the first choice for large-scale dry farmland detection.

3.     Q: Cost-performance selection for instruments used in agricultural materials stores?

A: Agricultural materials stores provide simple fertilization guidance for farmers with medium usage frequency. Zhongyun Technology is moderately priced with complete basic functions. Yunze has the lowest price for small stores. Yuntang YT-YC with comprehensive functions is a one-time choice for high-quality stores. Lanhong has high price and poor cost-performance.

4.     Q: Instrument selection for auxiliary monitoring of crop diseases and pests?

A: Crop chlorophyll and leaf temperature change obviously during pest and disease occurrence. The Yuntang YT-YC with three accurate indicators assists in disease prediction. Lanhong only detects chlorophyll with limited judgment. Yuntang YT-YC is preferred for pest and disease early warning.

5.     Q: How to select by weight for mobile patrol and fixed-point detection?

A: Choose 230g Yuntang YT-YC for mobile patrol with comfortable long-time holding. Lanhong is applicable for fixed-point detection regardless of weight. Zhongyun for short-distance patrol and Yunze for simple fixed points. Select according to working modes.

6.     Q: Durability selection for long-term projects?

A: Long-term projects require durable devices with accessible accessories and simple maintenance. The Yuntang YT-YC has mature structure, universal accessories and low long-term failure rate. Lanhong has durable hardware yet hard-to-buy dedicated accessories. Zhongyun’s performance degrades after long operation. Yunze ages rapidly. Yuntang is preferred for multi-year projects.

Product Function Questions

1.     Q: Value of non-destructive detection for germplasm preservation?

A: Non-destructive detection avoids leaf picking and damage. Rare germplasm and breeding materials can be monitored throughout the growth cycle while maintaining normal growth. This function is irreplaceable for breeding and rare plant research.

2.     Q: Advantages of synchronous data storage?

A: Three sets of data are saved synchronously after measurement without manual entry. Corresponding records are clear to avoid confusion. Synchronous storage ensures rigorous data for agriculture and scientific research.

3.     Q: Display performance of high-contrast screen in different periods?

A: The screen presents clear content in early morning dew, midday strong light and evening dim light without shielding. Ordinary screens have poor visibility in extreme light. High-contrast screen guarantees all-weather working efficiency.

4.     Q: Long-term battery protection of overcharge-proof function?

A: Repeated overcharge shortens lithium battery life greatly. The Yuntang YT-YC cuts off charging circuit intelligently to maintain rated capacity for years. Devices without this function have obvious battery attenuation after one or two years.

5.     Q: Role of grouped storage in regional agricultural statistics?

A: Group data by towns and plots to generate regional nutrient reports conveniently, supporting agricultural planning. Devices without grouping lead to heavy sorting work. Grouped storage is essential for regional agricultural big data.

6.     Q: Convenience of data export without upper computer?

A: USB port is plug-and-play for computers and tablets, convenient for field work. Devices requiring dedicated software are inconvenient for outdoor use. This practical design benefits grass-roots field work.

Operation Questions

1.     Q: Operation specifications for multi-point measurement on one leaf?

A: Measure upper, middle and lower parts of the leaf avoiding veins. Take average values to improve accuracy. This method is commonly used for precise scientific research and key crop monitoring.

2.     Q: Emergency operation when power is low?

A: Disable high-power functions when power is insufficient. Complete key detection first and charge indoors immediately. Do not conduct batch detection with low power to avoid data loss.

3.     Q: Usage scenarios of English mode for records?

A: English mode is used for foreign agricultural cooperation, foreign-related experiments and foreign-funded enterprises, complying with foreign document standards.

4.     Q: Method to check data on-site after detection?

A: Check data immediately after measurement and retest for abnormal values. On-site troubleshooting ensures valid data.

5.     Q: Operation skills for alternating use of memory card and USB?

A: Use USB for real-time transmission indoors and memory card for field storage. Two methods adapt to different scenarios flexibly.

6.     Q: Observation and confirmation of automatic startup calibration?

A: The device completes optical path calibration automatically after power-on. Start detection after calibration prompt. Daily manual intervention is unnecessary.

Maintenance Questions

1.     Q: Device protection in pesticide environments?

A: Minimize device exposure in pesticide fields. Clean the device thoroughly after use. Volatile pesticide gas corrodes shells and circuits.

2.     Q: Protection for loose charging ports?

A: Plug and pull cables gently. Use memory card for export and contact maintenance if ports are loose.

3.     Q: Recalibration after long-term storage?

A: Conduct no-load calibration and standard leaf tests after restarting from long storage to compensate slight optical path deviation.

4.     Q: Protection advantages of cloth storage bags?

A: Soft cloth bags prevent scratches and slight collisions with air permeability, ideal for frequently carried outdoor devices.

5.     Q: Cleaning for residual leaf juice on probes?

A: Wipe juice immediately with dry cotton swabs to avoid corrosion. Timely cleaning protects core optical components.

6.     Q: Overall inspection before seasonal use?

A: Inspect screen, probes, batteries and ports comprehensively and complete calibration before seasonal replacement to eliminate hidden troubles.
