Product information "Milwaukee MW804 waterproof high range pH / EC / TDS /Temperature Tester with replaceable probe"

Waterproof multi-parameter meter for measuring pH, conductivity, TDS, and temperature. The Milwaukee MW804 was specifically designed for applications involving higher conductivity and TDS levels and features automatic temperature compensation (ATC), automatic calibration, and a replaceable electrode.

Milwaukee MW804 Waterproof pH, Conductivity, TDS, and Temperature Meter – Compact All-in-One Meter

The Milwaukee MW804 is a versatile multi-parameter meter for the simultaneous determination of pH, conductivity, TDS (Total Dissolved Solids), and temperature. By combining several key water parameters into a single device, the meter is ideally suited for applications requiring reliable monitoring of water quality and mineral content.

Compared to the Milwaukee MW803, the MW804 was developed for applications with higher conductivity and TDS levels. This makes the device particularly suitable for use in agriculture, aquaculture, and water treatment, as well as in applications involving elevated salt and mineral concentrations. Simultaneous parameter monitoring enables a comprehensive assessment of water quality and reduces the effort required for individual measurements.

To ensure reliable results, the MW804 features automatic temperature compensation (ATC). Temperature-related effects on conductivity and TDS measurements are automatically accounted for, ensuring consistent readings even under changing environmental conditions. Additionally, the sample temperature can be directly measured and monitored.

The replaceable electrode ensures a long service life and cost-effective maintenance. Should the electrode wear out or sensor performance decline, it can be replaced without needing to replace the entire meter. This reduces ongoing costs and simplifies device maintenance.

Automatic calibration facilitates quick and convenient setup. One- or two-point calibration is available for pH measurement, while conductivity measurement utilizes automatic one-point calibration. This allows the device to be easily adapted to various measurement tasks.

Thanks to its waterproof housing, the MW804 is suitable for both laboratory use and mobile outdoor measurements. Its robust construction and ease of use make it a reliable solution for professional users and demanding monitoring applications.
