EZ4000/5000 Alkalinity / water hardness analyzer

Measuring method:

The EZ4000/5000 series water hardness analyzers use EDTA colorimetric titration and photometric colorimetric titration respectively for water hardness measurement; the EZ4000/5000 series alkalinity analyzers use acid-base titration for total alkalinity measurement.
