説明
SPECIFICATIONS
Brand Name: ComWinTop
Origin: Mainland China
Model Number: CWT-soil
Important Reminder
The measurement of NPK adopts the general rapid detection method, so there are certain error, Use with caution for planting reference.
However, the sensor supports the function of writing NPK data. You can use standard instruments to measure NPK then write in to provide data for monitoring system.
Measuring and Logging Soil Moisture Temperature Humidity EC PH NPK Sensor with HMI touch screen
CWT-SOIL sensor is for soil temperature and moisture, PH, conductivity (EC),measurement, compared with the original German high-precision sensors and soil drying method of weighing the actual calibration, high precision, fast response, stable output. By the soil salt content of small, suitable for all kinds of soil. Long-term buried in the soil, resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof.
Note: this product does not has inside battery. It must be powered by external power source.
if you need it with inside battery, take a look at this one:
