Product information "Milwaukee MW803 waterproof low range pH / EC / TDS /Temperature Tester with replaceable probe"

Waterproof multi-parameter meter for measuring pH, conductivity, TDS, and temperature, featuring automatic temperature compensation (ATC) and a replaceable electrode. The Milwaukee MW803 was specifically designed for applications in the low conductivity range.

Milwaukee MW803 Waterproof pH, Conductivity, TDS, and Temperature Meter – Compact All-in-One Meter

The Milwaukee MW803 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 one compact unit, the meter is ideal for users who need to monitor water quality quickly and reliably without relying on multiple separate devices.

The MW803 was specifically developed for low-conductivity applications. This makes the device particularly suitable for hydroponics, drinking water analysis, aquarium maintenance, and other applications involving low salt and mineral concentrations. Simultaneous measurement of multiple parameters simplifies water quality assessment and supports efficient monitoring of water and nutrient solutions.

To ensure precise results, the meter features automatic temperature compensation (ATC). Temperature-related fluctuations are automatically accounted for during conductivity and TDS measurements, ensuring reliable readings even under changing environmental conditions. Additionally, the integrated temperature sensor allows for direct monitoring of the sample temperature.

Another advantage of the Milwaukee MW803 is its replaceable electrode. Should the electrode wear out or its performance decline, it can be replaced without needing to discard the entire meter. This reduces long-term costs and significantly extends the device's service life.

Automatic calibration ensures simple and convenient setup. One- or two-point calibration options are available for pH measurements, while conductivity measurement utilizes automatic single-point calibration. This allows the device to be quickly adapted to various measurement requirements.

The waterproof housing protects the meter during use in damp environments, making the MW803 a reliable solution for both mobile and stationary applications. Its robust construction and ease of use make the device an attractive choice for both professional users and demanding hobbyists.
