Description

Overview

The Milwaukee EC40 is a long-body EC/TDS nutrient meter designed for hydroponics and greenhouse growers. Its 420 mm length lets it reach deep into nutrient tanks and reservoirs, measuring conductivity and total dissolved solids directly where the solution is mixed and stored.

A graphite electrode with a built-in temperature sensor provides automatic temperature compensation for stable readings, and the meter is factory calibrated so it is ready to use straight out of the box. Powered by three AA batteries with about three years of life, the EC40 is a practical everyday tool for monitoring nutrient strength.

Key Features

Measures EC (0.2–4 mS/cm) and TDS (up to 2800 ppm)
Purpose-built for hydroponic and greenhouse nutrient solutions
Long 420 mm body to reach into tanks and reservoirs
Graphite electrode with a built-in temperature sensor
Automatic temperature compensation (5.0 to 50.0 °C)
Factory calibrated — no calibration required
Accuracy of ±4% of reading ±1 resolution point
Selectable TDS factor (x0.5 / x0.7)
Powered by three AA batteries with about 3 years of life

Applications

The Milwaukee EC40 is used in hydroponics, greenhouses and horticulture to monitor the nutrient strength (EC/TDS) of feed solutions in tanks and reservoirs, helping growers keep plants correctly fed.
