YD300
Portable Water Hardness Meter
Introduction
●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.
