AK47 - pocket photometer for measuring fluoride in water

The AK47 tester enables simple measurement of fluoride in water within the 0.00–2.00 ppm range.

The AK47 tester is designed to determine fluoride ion concentrations in water using the SPADNS colorimetric method. The device enables reliable analysis—whether in the field or the laboratory—facilitating the monitoring of fluoride levels in environmental, industrial, and public health applications.
