It lacks salinity, electrical‑conductivity and pH‑measurement functions, with a storage capacity of merely 50 000 records and no 4G cloud‑platform‑upload capability. It applies only to simple soil‑moisture observation and cannot support saline‑alkali‑land or soil‑pH surveys.YT‑TRC (CNY 6 800): Four‑parameter soil tester for moisture, temperature, salinity and electrical conductivity, without a pH channel. It stores 150 000 records with USB export but no 4G‑network upload. Suitable for field‑monitoring assignments that do not require soil‑pH testing.YT‑WSYP+ (CNY 8 200, teaching‑recommended‑model): Complete five‑parameter instrument with integrated probe for moisture, temperature, salinity, electrical conductivity and pH. It supports 300 000‑record large‑capacity storage, manual / auto‑interval sampling, and 4G uploading to the smart cloud‑agriculture platform. It simultaneously displays salinity and electrical‑conductivity readings and is well‑suited for university agriculture‑and‑forestry laboratories to carry out classroom field‑training, undergraduate graduation design and faculty field‑pot‑based‑scientific‑research experiments requiring full‑set soil‑indicator measurement.YT‑TRX07 (CNY 36 800): Multi‑channel bench‑top large‑scale soil‑analysis equipment for laboratory‑batch analysis of pre‑processed samples. It is not designed for hand‑held in‑situ field‑site work and targets county‑level testing laboratories for indoor‑analysis work.Scenario‑based‑Selection‑RecommendationsFor university agriculture‑and‑forestry laboratories conducting classroom group field‑training, pot‑and‑field‑plot‑based‑scientific‑research experiments requiring full five‑soil‑parameter measurement: prioritize YT‑WSYP+.For simple soil‑moisture observation without salinity and pH‑measurement requirements: select YT‑TR01 for budget control.For research projects without pH‑measurement requirements: choose YT‑TRC.For laboratories focusing on indoor‑batch‑sample‑analysis instead of field‑hand‑held work: select YT‑TRX07.【Instrument Installation Procedures】Unpacking & Inspection: Open the aluminum‑alloy hard protective carrying case. Inspect hand‑held main‑unit, integrated‑sensor probe, charging adapter and USB‑communication cable for completeness. Check the sensor metal‑sensing surface for collision damage. Contact Yuntang national after‑sales outlets for immediate handling upon transportation‑caused damage.Environmental Requirements: Place main‑unit on dry surface during field‑site work; avoid direct rain splashing onto instrument. Prevent hard‑object impact on sensor probe.Sensor Assembly: Firmly insert plug of integrated five‑parameter‑sensor probe into main‑unit‑sensor port. The main‑unit automatically recognizes connected‑sensor assembly.Power‑supply Setup: If built‑in lithium‑ion battery has low power, fully charge hand‑held main‑unit using genuine‑factory‑charging adapter. Field‑site‑operation relies on built‑in‑battery power.System Initialization: Power‑on and enter color‑LCD main‑interface, verify system time. Familiarize yourself with menus for manual storage and auto‑interval sampling. Confirm USB‑port identification works normally. Configure 4G‑module network to connect to smart cloud‑agriculture platform.Pre‑test Verification: After assembly, run pre‑test on standard‑soil site to confirm sensor‑identification and reading‑response are normal. Hardware‑installation is completed and soil‑measurement work for student experiments can commence.【Instrument Operating Procedures】Power‑on hand‑held main‑unit with lithium‑ion‑battery power supply.
