Hardness analyser DUROMAT Professional

Hardness analysis (total hardness, residual hardness) with graphic display of the result.

Colorimetric analyzer, with microprocessor for water hardness analysis.
Example of use: hardness control after a water softener, for a reverse osmosis plant protection.
