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
  • Adaptation of the USEPA Method 330.5 and Standard Method 4500- CL G & adaptation of the phenol red method

Love the look, but Narrow
Size: 10, Color: Marine Blue/Woodbury/Ivory
What is for my son-in-law, he loves them, but had to switch them out twice because they run very narrow. He doesn’t have a wide foot at all so be careful when you purchase. Other than that they are a good looking shoe and he really likes them.

Awesome value shoes
Size: 11.5, Color: Ivory/White/British Tan, Size: 11.5, Color: Ivory/White/British Tan
These white Cole Haan shoes are just what I hoped for, the color is a perfect off-white, somewhere between cream and pure white, which gives them a more refined look. The quality feels excellent, they’re very comfortable right out of the box, and the laces feel durable and well-made. They fit true to size with no issues. Based on this experience, I’ll definitely be buying more from this brand in the future especially at this price point.
