Milwaukee MI411 pH and Free & Total Chlorine PRO Photometer

Milwaukee MI411 PRO Photometer is designed for fast, reliable and repeatable results in a portable and easy to use unit. Ideal or use in aquaculture, water conditioning, commercial pool maintenance, and water quality analysis education. Low maintenance rugged housing is built to take knocks.

MI411 PRO has a microprocessor that delivers fast, repeatable results with accuracy of ±0.06 mg/L @ 1.50 mg/L (Cl) | pH +/- 0.1. MI411 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 ensuring consistency across multiple users.

Features:

  • Easy measurement: just mix the reagent in the sample, gently shake, insert the cuvette, zero the meter, and then press read
  • Zero-point calibration:  Simply insert the unreacted sample cuvette into the chamber, index the cuvette, and press the zero button.
  • Built-in error messaging 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.
  • 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.
  • 9-volt battery included

GOOD
Color: Black
The chair was more comfortable than I expected for the price. The back support feels good and the seat does not feel hard after working for several hours. I liked that the wheels roll smoothly and the assembly was pretty simple. The design also makes the office look more modern. So far it feels stable and durable.

Sitting on a very comfortable leather chair
Color: Black, Color: Black
I have been using this chair for a few days. First of all, the installation is very simple and convenient. You can learn it just by looking at the drawings. It takes about 20 minutes to install. The chair is very comfortable to sit on. Its support and comfort are beyond expectations. It can relieve the fatigue of the waist and you won't feel very tired when sitting. The leather material is also good. It can be rotated, moved up and down, and can be moved. The armrests can also be moved up and down. This price is worth it. Overall, I'm very satisfied and comfortable.

Very comfortable chair!
Color: Black
This office chair is a great addition to my bedroom. It offers really nice comfort because of its thick and cushioned back which helps make long hours at a desk much more enjoyable. The adjustable height is really nice as it makes this chair extremely versatile. The armrests are sturdy and positioned well for typing or resting your arms. They also move back if you don’t like them.  The assembly was straightforward and didn’t take long as the instructions were clear and easy to follow. The wheels roll really nice and don’t get stuck. This chair is really comfortable and nice.
