Hardness analysis (total hardness, residual hardness)
and alkalinity of the water (carbon hardness, positive m value)
(with graphic display)

Multifunctional microprocessor analyser for the analysis of the amount of iron in water with measuring range:

Water hardness (total and residual)

French degrees: 0,022 – 53,57 °f
German degrees: 0,012 – 30°dH
English degrees: 0,02 – 37,59 °e
ppm CaCO3: 0,22 – 534 ppm CaCO3
mmol/l: 0,002 – 5,3 mmol/l
mg/l: 0,22 – 534 mg/l

Alkalinity (carbon hardness, positive m value)

French degrees: 0,54 – 40,2 °f
German degrees: 0,3 – 22,5 °dH

The analyser is complete with:
display of the measured hardness result.
2 programmable relay outputs: maximum value, alarm and/or fault
1 0(4) -20mA output: result of the analysis (linear hardness) and operation
1 digital input: start analysis.
SD card connection: data / results / error saving and transfer with date and time, software update.
A bad analysis can be repeated (just exceeded the maximum value, without giving an alarm signal)
Extensive program of operation control, relay drive, Leeds drive, accessory control.
Steps of an analysis cycle: opening an inlet solenoid valve – washing the measuring chamber for a settable time – checking the transparency of the water (zero point) – dosing the indicator by a peristaltic pump – result of the measured hardness (with display of the measured hardness) – final washing of the measuring chamber – the equipment stops waiting for the next analysis (timed, volumetric, manual or external signal start).

Certifications / instructions:
– CE certification
– documentation in English (on request: Italian, French, German etc.)
