Water Hardness digital Meter Benchtop laboratory tester YD-200

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

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.
