Milwaukee TDS Meter – MW401

The MW401 is a portable Total Dissolved Solids (TDS) meter with automatic temperature compensation. This instrument was developed for aquariums, aquaculture, laboratories and water treatment applications, serving everyone from hobbyists to professionals.

It is also an excellent choice for food laboratories and drinking water treatment applications.

TDS measurement provides an effective way to optimise chemical use and reduce operating costs.

In aquariums and aquaculture, high TDS concentrations can reduce water clarity and decrease the photosynthesis of aquatic plants.

In water treatment, a high TDS level can affect the clarity and taste of drinking water.

The MW401 has a range of 0 to 1990 mg/L (ppm), with a resolution of 10 mg/L (ppm).

This meter is supplied with a conductivity probe with a 1-metre (3.3 ft) cable and calibration solution.
