HI 93735

Full Range of Total Hardness in ppm, °fH, °dH and °eH

Total hardness, that is the presence of magnesium and calcium, is due mainly to the run-off water dissolving these salts as it flows or filters through different strata.

Hardness can also cause scaling of pipes in cooling and heating systems. Reverse osmosis and demineralization also increase hardness levels.

The HANNA® hardness meter, HI 93735, measures total hardness in three different scales: 0 to 250, 200 to 500 and 400 to 750 ppm, covering an extensive range of applications.

With HI 93735 hardness can be measured in ppm (mg/L) as well as in French (°fH), German (°dH) and English hardness (°eH).

The reading is expressed directly in ppm and it is not necessary to use conversion tables and diagrams for interpretation.

Order Information:
HI 93735 is supplied with 2 cuvets, battery and instructions.
