This 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.
The meter is the perfect products with advanced electronic, sensor and software design technology. It used in the measurement of high accuracy water hardness value and it is more suitable for measurement in field and scene.
For notable features read as follows:
1.1. Adopts 601-S water hardness combination electrode which consists of measuring electrode, reference electrode and temperature probe. At the same time, its new structure, stable electrode potential, quick response and use easily features are more welcomed by customers.
1.2. The electronic unit adopts intelligent chip design, which has automatic calibration, automatic temperature compensation, data storage; measuring value can be locked automatically and automatic power off and low potential displaying function etc.
1.3. Eight water hardness units can be chosen freely: mmol/L, mg/L (CaCO3), mg/L (CaO), mmol/L (Boiler), mg/L (Ca), ◦fH (France Degree), ◦dH (German Degree) and ◦eH (England Degree).

1.5. Equips B1, B2 and B3 three calibration solutions.
1.6. LCD display with blue background.
1.7. Meter’s circuit board adopts SMT film-covering technology to improve
meter’s production reliability.
1.8. Reliable waterproof design (waterproof grade IP57).
1.9. Special carrying case equips with all accessories and more convenient for using.
2. Technical Parameter:
2.1. 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
