Product Overview


It is cccurate to ±0.01 pH with automatic or manual temperature compensation, and built in dedicated GLP key. In addition, up to 3-point automatic calibration and 7 selectable buffer standards makes the MW160 MAX ideal for use by brewers, wine makers, growers, labs, food processing, water treatment and many other applications with challenging pH measurement needs.

The Milwaukee MW160 4-in-1 MAX pH/ORP/ISE/Temp Logging Bench Meter is preferred by people testing all types of samples viscus or not, in a variety of applications that cause other pH meters and electrodes to fail. The MA917B/1 Milwaukee double junction electode is refillable and easy to clean. From brewers and wine makers to hydroponic growers, labs and water treatment, the MW160 MAX is your Bench Meter for fast, accurate readings.
