Milwaukee MI404 PRO Free & Total Chlorine Photometer

Overview

The Milwaukee MI404 PRO is a portable photometer for measuring both free and total chlorine in water. Covering 0.00 to 5.00 mg/L of Cl2, it gives clear digital readings that remove the guesswork of visual test kits, making chlorine monitoring fast and consistent in the field or laboratory.

A tungsten lamp with a 525 nm narrow-band interference filter and a silicon photocell detector deliver stable photometric results, following an adaptation of USEPA method 330.5 and Standard Method 4500-Cl G. Portable and powered by a single 9 V battery, the MI404 comes with glass cuvettes for immediate testing.
