Detailed Description

Product IntroductionThis meter adopts electrode method to test water hardness, which be proved that it has the same accuracy as the EDTA volumetric method after doing a great deal experiments, meanwhile It can avoid many shortness points of EDTA method, such as complicated operation and judgmental difficulties etc. Technical Parameter: Units and Its Conversion of Water Hardness: mmol/L —basic unit for water hardness mg/L (CaCO3) — water hardness based on quality concentration of CaCO3, or we call it ppm and U.S. Degree. mg/L (CaO) —water hardness based on quality concentration of CaO mmol/L (Boiler) — special unit for industrial boiler water hardness measuring mg/L (Ca) —water hardness based on quality concentration of Ca ºfH—France Degree ºdH—German Degree ºeH—England Degree Main ParameterTechnical Parameter: Water Hardness: Measuring range (0 ~ 10)mmol/L; (0 ~ 401)mg/L(Ca); (0 ~ 1000)mg/L(CaCO3); (0 ~ 100)ºfH(France Degree); (0 ~ 561)mg/L(CaO); (0 ~ 56)ºdH(German Degree); (0 ~ 20)mmol/L(Boiler); (0 ~ 70)ºeH (England Degree). Resolution 0.01 and 0.1 water hardness units Accuracy ±5% FS Temp. compensation range (5 ~ 50)°C(automatic) Calibration Solution B1 Calibration Solution — 2.00×10-2 mmol/L B2 Calibration Solution — 2.00×10-1 mmol/L B3 Calibration Solution — 2.00 mmol/L (B3 Calibration Solution also can be used for the soaking solution of electrode) Calibration Mode (a) B1/B2 Calibration—using B1 and B2 Calibration Solution,suitable for < 2.00×10-2 mmol/L low concentration water quality,for example, boiler water. (b) B2/B3 Calibration—using B2 and B3 Calibration Solution,suitable for general water quality. Temperature: Measuring range 0 ~ 60°C Resolution 0.1°C Accuracy ±0.5°C
