The Milwaukee MI412 PRO Photometer features manual zero-point calibration and fast operation in a rugged design.

The Milwaukee PRO Photometer is ideal for users in aquariums, aquaculture & coral, food, and water treatment applications. This meter is also ideal for educators that want their students to learn the basics of water quality analysis to apply in the real world.

The Milwaukee PRO Photometer offers:

Speed

The MI412 microprocessor delivers fast results with an accuracy of ±0.07 mg/L @ 1.00 mg/L PO4 and is repeatable.

Easy To Use and Toughness

This rugged meter is designed to take knocks. Its low maintenance design paired with easy-to-use reagents makes the MI412 ideal for everyone from educators and pool professionals to brewers and growers.

• Fast easy to read results with a large digital LCD readout.
• Accurate to ±0.07 mg/L @ 1.00 mg/L and a range 0.00 to 2.50 mg/L of PO4.
• Lightweight and portable.
• Easy measurement: just mix the reagent in the sample, gently shake, insert the cuvette, zero the meter then press read.
• Simple easy reagent packets or liquid bottles.
• Easy 1-2-3 instruction steps.
• Auto shut off after 10 minutes of non-use, 9 volts (battery included).
• Adaptation of the Ascorbic Acid Method.

Built In Timer

MI412 has a built-in timer that ensures appropriate reaction time is used for the chemical reaction. At the end of the timer, the meter will automatically take the reading. This feature ensures consistency across multiple users.

Cuvette Chamber

The MI412 has a built-in indexing indent on the meter - The meter has an indent that 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.

Error Messaging

The MI412 has built-in error messaging display alerts. 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 to ensure the user has the most accurate error-free readings.

Calibration

The MI412 has a simple-to-use zero-point calibration. Simply insert the unreacted sample cuvette into the chamber, index the cuvette and press the zero button. Your calibration is complete.
