The Milwaukee MW803 MAX Waterproof 4-in-1 Tester is designed as an all-in-one solution for growers. It takes ±0.05 pH, EC/TDS at 2% full scale and ±0.5°C / ±1°F for temperature.

A large two-level LCD screen makes it easy to read results while a stability indicator and reset function freeze the display. With automatic calibration and 5 memorized calibration points, the tester can be quickly and easily calibrated for greater accuracy compared to manual calibration. It is designed with a double junction probe that offers a longer service life. The tester is lightweight and fully waterproof to IP67.


Quick, easy-to-read results with large digital dual LCD readout
Extreme accuracy for ±0.05 pH, EC / TDS 2% Full scale and temperature ±0.5 C / ±1 F

Milwaukee MW803 Manual


All pH sensors have a limited life and response time gets longer with age. Properly maintaining the pH PRO test will give you fast, accurate results for longer.

CE sensors are more robust, but can still be affected by residue buildup.

Here are some tips:

Always store with the cap full of buffer or MA9015 storage solution, not water.
Clean the tester regularly by dousing it with MA9016 cleaning solution.
Calibrate after cleaning and/or storage before testing to adjust for changes in pH and EC sensor.
Gently stir the PRO tester into the sample to get a faster result
Rinse in water after each test
