HTR320 series soil sensor is a high-precision and sensitive sensor for online measuring soil humidity / soil temperature / soil conductivity(EC) / soil PH / soil NPK. Compared with the original high-precision sensor of Germany and calibrated by the actual drying and weighing method of soil, it has high precision, fast response and stable output. Agricultural sensor series products are widely used in agricultural greenhouses, ﬂower cultivation, pasture grassland and other occasions.
H:0%-100% / T: -40ºC~+80ºC
H:±3%(5%~95%,25ºC), T: ±0.5ºC(25ºC), EC: 10us/cm, PH: ±0.3PH, NPK: ±2%F.S
Maximum power consumption
-40ºC- +80ºC, 0 - 100% (soil temperature&humidity+soil EC), 0 ~+55ºC, 5%-95% (soil PH), 5 ~ +45ºC, 5%-95% (soil NPK)
≤1%/year (soil temperature&humidity+soil EC), ≤5%/year (soil PH+NPK)
epoxy resin (black flame retardant)
2m(default) / customized
Excellent sealing performance
The high-density epoxy resin is filled between the sensor body and probe, prevent moisture entering.
Waterproof & anti-corrosive shell
Ensure stable monitoring of components, the sensor body is waterproof and reach IP68 protection level.
Austenitic 316 stainless steel probe
Rust proof, resistance to point solution, salt and alkali corrosion, ensure long-term operation of probe part. Therefore, it is
suitable for all kinds of soil.
