MW180 MAX | Bench Meter

MW180 MAX pH / ORP / Conductivity / TDS / NaCl / Temperature Laboratory Bench Meter

The Milwaukee MW180 5-in-1 MAX pH/ORP/EC/TDS/NaCl/Temp. Logging Bench Meter has won fans around the world with its reliable, fast and simple operation as well as its tough, sleek design and small benchtop footprint. It is accurate to ± 1% of reading for EC/TDS/NaCl and up to +/-0.002 pH, with automatic or manual temperature compensation and a built in dedicated GLP key. Ideal for use by education, horticulture, labs, food processing, water treatment and many other applications with challenging pH/ORP/EC/TDS/NaCl/Temp. measurement needs.

Fast easy to read results with large duel level digital LCD readout.
Extreme accuracy to +/-0.002 pH and 1% of reading for EC/TDS/NaCl |+/- 0.4°C (+/-0.8°F).
Extended ranges for pH/ORP/EC/TDS/NaCl.
