HI 8424 portable pH/ORP meter/thermometer (pH/ORP/T)

HI 8424 Handheld instrument with remote (replaceable) electrode for measuring pH, ORP and temperature in water and solutions to monitor water quality in water treatment processes, environmental studies, swimming pools, etc. With automatic pH calibration and thermocompensation.

 

Calibration is automatic on one or two points with three buffer values (pH 4.01, pH 7.01 and pH 10.01). Once the instrument has been calibrated, the buffer values used during the calibration process are displayed on the LCD screen.
