8 In 1 Soil Moisture Temp EC Salinity NPK PH Sensor (RS485)

Description

1. This sensor integrates 8 parameters of soil water content, temperature, conductivity, salinity, N, P, K, and PH.
2. ABS engineering plastic, epoxy resin, waterproof grade IP68, can be buried in water and soil for long-term dynamic testing
3. Austenitic 316 stainless steel, anti-rust, anti-electrolysis, fully sealed, resistant to acid and alkali corrosion.
4. High precision, low threshold, few steps, fast measurement speed, no reagents, unlimited detection times.
