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. |
