Milwaukee MI407 Ammonia Low Range PRO Photometer

Milwaukee MI407 PRO Photometer is easy to use with fast, reliable and repeatable results. Designed for use in water treatment and conditioning, such as aquaculture, environmental, laboratory and educational applications. 

Rugged casing is designed to take knocks, protecting the internal microprocessor that delivers results with accuracy of ±0.09 mg/L @ 1.50 mg/L that display on the large LCD readout. Auto shut off after 10 minutes of non-use, 9-volt battery included. Adaptation of The Nessler Method.


  • Easy measurement: just mix the reagent in the sample, gently shake, insert the cuvette, zero the meter, and then press read.
  • Built-in timer: Ensures appropriate reaction time is used for each reading.  At the end of the timer, the meter will automatically take the reading ensuring consistency across multiple users.
  • Built-in indexing indent: allows for a lock and key fit with the cuvette cap. Ensures that the cuvette is indexed consistently (same position) in order to maintain the same path length for accurate results.
  • Built-in error messaging display:  User friendly display ensures no mistakes are made in the testing process.  Messages include no cap, over range and under range, light source errors, and zero cal error.   
  • Zero-point calibration:  Simply insert the unreacted sample cuvette into the chamber, index the cuvette, and press the zero button.
