TR03Soil Monitoring
Soil Moisture, EC and Temperature Sensor
Measures soil moisture (volumetric water content), electrical conductivity (EC), and temperature. Moisture range 0–50% or 0–100%, EC up to 20000 µS/cm, temperature -40~80°C with ±0.5°C accuracy; output options include RS485 Modbus, analog voltage 0–2V, or current 4–20mA. Suitable for scientific research, irrigation, greenhouse, and smart agriculture.

TR03 questions
What ranges are available for the TR03?
Standard coverage is 0–50% or 0–100% by model. Other spans, outputs, and process connections can be sourced to match the application. Send the working pressure and medium and we will confirm the exact option.
What is the MOQ and lead time?
1 pc (flexible, no minimum for most products). 2-3 days for in-stock items, 15-30 days for custom orders. Samples are available, with freight on the buyer’s account.
Can the TR03 be customized?
Range, output signal, process connection, cable length customizable through our supply partners.
Do you manufacture this transmitter?
SIBXSUN is an industrial instrumentation supplier in Ningbo, not the factory. We source the TR03 from qualified partners, inspect before shipment, and handle export documents and logistics.
Need the right soil moisture, ec and temperature sensor for your process?
Send the medium, range, output, and quantity. We will confirm the matching option and a FOB Ningbo quote.
