Description

Overview

The Milwaukee C66 is a waterproof, high-range conductivity (EC) pen for reliable measurement of electrical conductivity in water. Measuring 0.00 to 10.00 mS/cm, it suits hydroponics, aquaculture, cooling water and general water-quality checks where higher conductivity levels are involved.

Its floating, waterproof housing and replaceable MA73076 electrode make it durable and cost-effective over time, while automatic temperature compensation keeps readings accurate from 0 to 50 °C. Powered by three 1.5 V batteries with around 250 hours of use, the C66 is a dependable everyday field tester.
