Water hardness meters YD200 or YD300

Description

Adopt model **1 water hardness combination electrode which consists of measuring electrode and temperature ***** PVC sensitive membrane of measuring electrode is made of active matter comes from new neutral carrier, which has equal selectivity for Ca²+ and Mg²+ ion in water sample. It has features of new structure, stable electrode potential, quick response and use easilly. The electronic unit adopts intelligent chip design, which has intelligent function of automatic calibration, automatic temperature compensation, data storage and automatically lock measuring value etc. Eight water hardness units can be selected freely : mmol/L, mg/L mmol/L(Boiler), mg/L(Ca), º fH, ºdH, º eH. Equip with B1, B2and B3 calibrting solution. Model YD**0 is waterproof design(Waterproof Grade IP*7) and equips with a special carrying case. Model YD**0 equips with WH-Link communication software can send the testing data of instrusment to PC.
