ant Reminder

The measurement of NPK adopts the general rapid method, so there are certain error, Use with caution for planting reference.

However, the r supports the function of writing NPK data. You can use standard instruments to measure NPK then write in to provide data for monitoring system.

RS485 4-20mA Temperature Humidity Moisture Conductivity EC PH r

CWT- r is for temperature and moisture, PH, conductivity (EC),measurement, compared with the German high-precision and drying method of weighing the actual calibration, high precision, fast response, stable output. By the salt content of small, suitable for all kinds of . Long-term buried in the , resistant to long-term electrolysis, corrosion resistance, vacuum potting, completely waterproof.
