PF-3 Drinking Water

The PF-3 drinking water photometer is part of the smallest member of the MACHEREY-NAGEL photometer family, providing a really handy way of carrying out site measurements.

It is simple and intuitive to use with just four buttons. Strong enough to resist the rigours of site work with shock resistant optics, reinforced housing and IP 68 rating.

Drinking water is a vital part of our lives, and cannot be replaced. Hence, it has to be wholesome and free of impurities that may adversely affect human health. Continuous water analysis is therefore fundamental for a sustainable and reliable drinking water supply.

The compact photometer PF-3 Drinking Water in combination with the proven VISOCOLOR® ECO tests allows quick and easy analysis. This gives us an excellent way of monitoring and checking the most important drinking water parameters (chlorine, chlorine dioxide, pH, fluoride and iron). The PF-3 can be used for all water suppliers and industrial users involved in drinking water treatment.
