yd300 portable water hardness meter
    portable meter for measurement of water hardness by electrode measurement method, suited in field and on site.

●portable 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, low voltage display, etc.
● ability to switch among eight units: mmol/l, mg/l (caco3), mg/l (cao), mmol/l (boiler), 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.
● ip57 waterproof rating, equipped with portable case, calibration solution and other accessories.
