Compact Photometer

PF-3 Soil

The PF-3 soil 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.

Monitoring and reliable analysis is a cornerstone in supporting and maintaining healthy, productive and biologically active soil. To effectively and efficiently plan all measures that affect the soil (fertilization, liming, etc.), it is crucial to determine the important soil parameters (Nitrate, Phosphate, Potassium and Ammonium).

The PF-3 Soil in combination with the proven VISOCOLOR® ECO Test kits and NANOCOLOR® tests are ideally suited for mobile analysis of the soil quality right at the point of interest.
