HANNA HI9811-5N pH/ EC/ TDS Meter

HANNA HI9811-5N pH/ EC/ TDS Meter waterproof meter designed for simplicity in taking pH, µ S/ cm, ppm ( mg/ L) and temperature measurements. both the HI 9811-5 and HI 9812-5 are ideal for hydroponics, greenhouses, farming and ground water applications.

Due to the built-in temperature sensor, conductivity readings are automatically compensated for temperature changes. The temperature coefficient is fixed
at 2% / ° C.

specially engineered HI 1285-5 pH/ EC/ TDS and temperature probe utilizes a fiber junction and gel electrolyte which provide a fast response and reduced contamination. This combination makes the HI 1285-5 particularly designed to withstand harsh environments such as fertilizer solutions.

Features :
