RECALIBRATION TECHNICAL INFO

CALCIUM HARDNESS COLORIMETER OVERVIEW

Total hardness, that is 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 cause scaling of pipes in cooling and heating systems.  Reverse osmosis and demineralization also increase harness levels.  The LHI93735 meter 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 this meter hardness can be measured in ppm (mg/L) as well as in French (^ofH), German (^odH) and English hardness (^oeH).  The reading is expressed directly in ppm and it is not necessary to use conversion tables or diagrams for interpretation.

The LHI93735 meter comes complete with 2 cuvets, battery and manual.
