For the analysis of the the quantity EDTA (ethylenediaminetetraacetic acid ) in water.

Colorimetric analyzers with display of the quantity of EDTA in water:
(with graphic display of the result)

Microprocessor multifunctional analyzer for the analysis of EDTA in water with measuring from 5 to 50 ppm.
Example of usage: control of conditioning in water.
You can program two set point of alarm (maximum two or one minimum and one maximum. The system DUROMAT® professional controls qualitatively the EDTA in water. This permits to avoid problems or damages because of no presence of EDTA in water, saving water, time and avoiding a possible overdose.
With display of result of the amount of EDTA.

4 output relais: maximum value one, maximum value two (or minimum value and maximum value), water cooler (or flush valve o pomp), alarm indicator, functional error.
1 output 0(4)-20mA: quantity of EDTA
1 output CAN BUS interface: functional data and measuring value
1 output/input SD: update and memorization of results
2 input: STOP analysis, START analysis, water meter, flowmeter

You might repeat a wrong analysis (just exceeded the maximum value, without giving an alarm signal. Wide control program of the functionig, driving relais, driving signals, control accessories.

How it performs analysis: opening a inlet solenoid valve – washing of the measuring valve for a settable time – control of the transparency of water (point zero) – dosage of liquid indicator by a peristaltic pump – result of the measured quantity of EDTA  (by display of measured EDTA ) – final wash of the measuring chamber – the apparatus stops waiting the next analysis (temporized start, volumetric, manual or with external signal).

– certification CE
– documentation in italian english, french, german, spanish language
