Photometric NPK determination using the AMOLA® and mobile nutrient analysis in the field with our STELZNER® soil kit – also includes reagents and indicators for the quick test

PF 12

Photometric nutrient analysis

The PF 12 digital photometer is the next innovative step for our photometric product line. This instrument can be used for any water or waste water analysis task and is perfectly suited to meet the present and future requirements of our customers. The PF 12 can be used in industrial or municipal waste water management, drinking water supply, ground water, surface water, coolant water and boiler water systems, and soil analysis. The state-of-the-art illuminated graphic display is menu driven and capable of clearly displaying all key information (measured result, date/time, sample number, etc.). The display also shows when measurements do not lie within the specified measurement ranges. Measurements that exceed the measurement range can be queried in order to evaluate the dilution used.
