This pH/EC/TDS/temperature probe probe features a fiber junction and gel electrolyte making it ideal for fertilizer solutions. It is a replacement electrode for the GroChek series "-5" models: HI9813-5 & HI9813-5N, and is designed for simplicity of use in taking pH, mS/cm, ppm and temperature in the °C scale measurements.
The meter the probe supports is a versatile, water resistant, multiparameter portable instrument specifically designed for agricultural applications such as hydroponics, greenhouses, farming, and nurseries. It features a large LCD that clearly displays the parameter being measured as well as calibration instructions. Calibration is fast and easy with knobs located on the front panel of the instrument.
