Monzana 2.1 Water Tester pH value Chlorine Testing Device

I liked all the same a reserve on the reliability of the indications. It may be a bit approximate.

This is the second time I have purchased this device, and I still cannot calibrate the chlorine... This probably comes from me...

The measurement of PH is simple and relatively effective, on the other hand the measurement of the chlorine level requires to make a first measurement and to compare the result with a chemical strip in order to make a visual calibration compared to lines indicated on the galvanometer (A / B / C / D or E) The measurement in the end is not precise enough in my opinion because the needle does not reach the lettered scale during calibration.

Seemed good quality and a rather nice design but did not work. Still waiting for a response from the after-sales service. The seller informs me immediately that he is sending me another one. Bravo for the reactivity

Difficult to use, the measurement is random and the calibration difficult to do. I regret my purchase. I stay with my little bottles of tester.
