The Master Science Benchtop Water Hardness Meter gives a direct reading of total hardness in water samples, from 0.05 up to 200 mmol/L. Results can be shown in mmol/L, mg/L, German degrees (°dH), English degrees (°e) or French degrees (°f), so the meter matches whichever unit your reports use.
Calibration runs on 2 to 5 points spread from low to high concentration. The Master Science Benchtop Water Hardness Meter compensates for temperature, locks the reading once it is stable, stores up to 500 data sets and passes them to a PC over USB.

Applications
The Master Science Benchtop Water Hardness Meter is used wherever water hardness must be checked, for example:
- Drinking water and water treatment laboratories
- Boiler and cooling water monitoring
- Quality control in food and beverage plants
- Environmental and teaching laboratories
Common Problems This Meter Solves
Hardness testing by hand has familiar weak points.
- Slow, operator-dependent titrations:: the meter gives a direct reading in the unit you select.
- Unit conversions cause errors:: five hardness units are built in.
- Overdue calibration goes unnoticed:: the due alarm can be set from 1 to 31 days.
- Results copied by hand:: 500 stored data sets move to a PC over USB.
