Measuring equipment to measure waterhardness

Hardness analysis (total hardness, residual hardness)
and alkalinity of the water (carbon hardness, positive m value)
(with good water/not good water signal)

Only the type of analysis needs to be programmed (waterhardness or alkalinity), no need to program the reagent type.
The Water Hardness Analyzer qualitatively checks the softening system and thus prevents problems or damage caused by the hardness of the water. This saves: water, time and chemicals required for any expected system regeneration.

Several messages appear on the display, which may refer to: fresh water inlet, too hard water, analysis in progress, analysis repeat (due to an initial result indicating too high hardness), analysis stop, pre-alarm, empty indication (exhausted to 100%), device failure

Steps of an analysis cycle: opening of an inlet solenoid valve – washing of the measuring chamber for a settable time – control of water transparency (zero point) – dosing of the indicator by means of a peristaltic pump – result of the measured waterhardness (with display of the measured waterhardness) – final washing of the measuring chamber – the equipment stops waiting for the next analysis (timed start, manual or with external signal).
