Analisi della durezza carbonica dell’acqua


Multifunctional microprocessor analyzer for water hardness analysis with alarm set point for:
French degrees: 0.05 / 0.09 / 0.18 / 0.36 / 0.54 / 0.9 / 1.8 / 3.6 / 5.4 or 9.0 ° f.
German degrees: 0.02 / 0.05 / 0.1 / 0.2 / 0.3 / 0.5 / 1.0 / 2.0 3.0 or 5.0 ° dH
ppm CaCO3: 0.4 / 0.9 / 1.8 / 3.6 / 5.4 / 9.0 / 18.0 / 36.0 / 54.0 or 90.0 ppm CaCO3
mmol / l: 0.004 / 0.01 / 0.04 / 0.50 / 0.09 / 0.18 / 0.36 / 0.54 or 0.90 mmol / l
The alarm set point is established by the indicator inserted without having to program it.
The DUROMAT® XII system qualitatively controls the softening system, this allows you to avoid problems or damage caused by the hardness of the water. This saves: water, time and chemicals that would be required for any early regeneration of the softening system.
Various LEDs are available for identifying the operation and results (good water / not good water).

LED signals: fresh water, hard water, analysis in effect, repetition of analysis (due to exceeding hardness), analysis stopped, indicator level pre-alarm <10%, indicator missing (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, washing of measuring chamber, 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 via 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, see: 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 water transparency (zero point) – dosage of the indicator by means of a peristaltic pump – result of the measured hardness (with hardness signal below / above the maximum limit) – final washing of the measuring chamber – the equipment stops waiting for the next analysis (timed start, manual or with external signal).
