Total Hardness Photometer HI 96735

Photometer for checking total water hardness

In our offer, you will find 3 models of photometers that accurately measure water hardness for magnesium, water hardness for calcium, or the total hardness present in water, as measuring water hardness is necessary in many areas of industry. The photometer for Ca and Mg hardness provides results in mg/l, while the model for total water hardness transmits the result in different units: ppm (or mg/l), °D German (German degree of hardness, see in the table), °f French, and °E English. The summative parameter of total hardness is basically extracted to assess total hardness (sum of the two types of Mg and Ca ions). This is necessary, for example, to prevent corrosion damage in piping and cooling installations. On the other hand, the hardness degree serves as an indicator of manure in waters (a healthy ratio of Ca / Mg ions is 4:1). Make your work easier and obtain accurate results, use one of our photometers.
