Description

Overview

The Milwaukee MW306 MAX is a portable, waterproof meter that measures conductivity (EC), total dissolved solids (TDS), salinity and temperature with data logging. Wide ranges — EC up to 500 mS/cm and TDS up to 400 g/L — and an IP67-rated housing make it ideal for field measurement in water treatment, aquaculture and agriculture.

The MW306 MAX stores up to 1000 samples, offers on-demand, stability and interval logging, and connects to a PC via micro-USB. It is supplied with an MA815D/1 4-ring EC probe with a built-in temperature sensor, and runs for about 200 hours on three AA batteries.
