HI 9811-5N pH/ EC/ TDS/ ° C PORTABLE METERS

HI 9811-5N
pH/ EC/ TDS/ ° C PORTABLE METERS
HI 9811-5 and HI 9812-5 are pH/ EC/ TDS waterproof meters designed for simplicity in taking pH, ¼ 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 . Conductivity measurements are automatically compensated for temperature changes with a built-in temperature sensor. The temperature coefficient is fixed at 2% / ° C. The 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 suitable to be used in fertilizer solutions. No probe changes are required when switching your measured parameter between pH, conductivity and TDS. These multiparameter meters reduce the number of instruments required for water quality analysis.
