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

Water hardness (total hardness, residual hardness)
French degrees: 0,05 / 0,09 / 0,18 / 0,36 / 0,54 / 0,9 / 1,8 / 3,6 / 5,4 o 9,0 °f
ppm CaCO3: 0,4 / 0,9 / 1,8 / 3,6 / 5,4 / 9,0 / 18,0 / 36,0 / 54,0 o 90,0 ppm
mmol/l: 0,004 / 0,01 / 0,04 / 0,50 / 0,09 / 0,18 / 0,36 / 0,54 o 0,90 mmol/l
German degrees: 0,02 / 0,05 / 0,1 / 0,2 / 0,3 / 0,5 / 1,0 / 2,0 / 3,0 o 5,0 °dH
Alkalinity of the water (carbon hardness, positive m value)

German degrees: 1,0 / 1,5 / 2,0 o 3,0 °dH

Only the type of analysis needs to be programmed (water hardness or alkalinity), it is not necessary to program the type of reagent.
The DUROMAT® XX analyser qualitatively checks the softening system, and this allows to avoid problems or damage caused by the hardness of the water. This save: water, time and chemicals that would be required for any anticipated regeneration of the system.
Various LEDS are available for identifying operation and results (good water / not good water).

LED signals: fresh water, hard water, current analysis, repetition of analysis (due to exceeding hardness), stop of analysis, indicator level pre-alarm <10%, lack of indicator (exhausted 100%), appliance malfunction.
At the output we have three alarm relays (overcoming hardness, malfunction alarm, analysis signal in force).
One entry for STOP or START analysis.
Buttons for: start of analysis, measurement chamber washing, relay reset and manual dosage.
Programmable analysis interval: 5, 10, 20 or 30 minutes. It is possible to operate the analysis manually.
A bad analysis can be repeated (as soon as the maximum value is exceeded, without giving an alarm signal).
Extensive function control program, relay drive, LED drive, accessory control.
Simple programming by microswitches.
Simple setting of the washing time through a potentiometer (settable from 30 seconds up to 10 minutes).
Minimum indicator consumption: 0.07 ml for each analysis.
No water consumption during the analysis downtime.

The purchase and maintenance costs are limited.
The device is intended for industries as well as for smaller realities, as apartment buildings, hotels, restaurants, laundries.

How the analysis takes place: opening of an inlet solenoid valve – washing of the measuring chamber for a settable time – control of the transparency of the water (zero point) – dosage of the indicator by means of a peristaltic pump – result of the measured hardness (with hardness signal below / above of the maximum limit) – final washing of the measuring chamber – the equipment stops pending the next analysis (timed start, manual or with external signal).
