yd200 lab. water hardness meter
    benchtop meter for measurement of water hardness by electrode measurement method, suited in school, research institution, laboratory of industrial and mining factory.

●benchtop meter for measurement of water hardness (the total concentration of calcium ion and magnesium ion).
●electrode adopts model 601-f water hardness combination electrode with patent structure. it consists of measurement electrode, reference electrode and temperature probe. replaceable measuring head, steady potential, fast response, easy to use.
●meter adopts intelligent chip design, automatic calibration, automatic temperature compensation, time display, data storage rs232 output, etc.
● ability to switch among eight units: mmol/l, mg/l (caco3), mg/l (cao), mmol/l (boiler) and mg/l (ca). three options of three units: ºfh(france)、ºdh (germany)and ºeh(uk) from wh-link communication software.
●equipped with b1、b2 and b3 calibration solution.
●equipped with wh-link communication software, connect testing data of meter to computer.
