Product Description

Product Description

  The independently developed chlamydoscope is a sensor based on the principle of dielectric constant, which can monitor the soil temperature and humidity of different soil layers quickly, accurately and comprehensively.
Our company's independently developed chlamydometer adopts TDR measurement method, which is a sensor based on the principle of dielectric constant; it can measure the soil temperature, humidity and conductivity of different soil layers
Rate, NPK were monitored quickly and accurately. The new TDR measurement instrument adopts non-contact measurement method, which enhances the measurement stability measurement accuracy will not deviate with the increase of time, and the special structure design greatly extends the service life.
The device supports a variety of communication modes, not only supporting the standard modbus485 protocol, but also including 4G, Lora and NB-IOT modes with low power consumption.
It is widely used in the monitoring of garden irrigation, soil moisture, agricultural guidance, water conservancy construction,mine monitoring, geological exploration, scientifific experiments and grass planting.
