Milwaukee MI407 Ammonia Low Range PRO Photometer

Milwaukee MI407 PRO Photometer is a rugged, lightweight, portable photometer, designed to take knocks. Low maintenance design is paired with easy-to-use reagents. Ideal for users in aquaculture, water conditioning, environmental and water treatment, and food processing.  The microprocessor delivers fast, repeatable results with accuracy of ±0.09 mg/L @ 1.50 mg/L that display on the large LCD readout.

Includes a built in timer, indexing indent, error messaging display, and zero point calibration. 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 the chemical reaction.  At the end of the timer, the meter will automatically take the reading ensuring consistency across multiple users.
  • Built-in indexing indent: on the meter which allows for a lock and key fit with the cuvette cap.  This 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:  This helps the user ensure 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.
  • Reagent Kit: Low Range Ammonia Reagent Kit
