Milwaukee MW401 PRO Low Range Total Dissolved Solids Meter

Overview

The Milwaukee MW401 PRO is a portable low-range TDS meter for measuring total dissolved solids from 0 to 1999 mg/L (ppm). Supplied with a separate SE510 probe on a cable, it lets the operator measure directly in tanks, containers and hard-to-reach samples — a practical everyday tool for drinking water, aquariums and hydroponics.

Automatic temperature compensation keeps readings accurate from 5 to 50 °C, and a starter calibration solution is included so the meter is ready to set up and use. Powered by a single 9 V battery with about 300 hours of life, the MW401 is a dependable field and lab tester.
