Milwaukee MW150 MAX Bench pH/ORP/Temperature Meter
The Milwaukee MW150 MAX Bench Meter is a professional laboratory instrument designed for highly accurate measurement of pH, oxidation-reduction potential (ORP), and temperature. Combining ±0.01 pH accuracy, automatic temperature compensation (ATC), up to three-point automatic calibration, and a refillable double-junction pH electrode, the MW150 MAX delivers dependable laboratory-grade performance for demanding testing applications.
Designed with a compact footprint that conserves valuable bench space, the MW150 MAX is ideal for water treatment plants, environmental laboratories, breweries, wineries, hydroponics, agriculture, food processing, aquaculture, research laboratories, and industrial quality control. The rugged design, intuitive controls, and dedicated Good Laboratory Practice (GLP) functions make it a reliable choice for professionals who require consistent, repeatable measurements.
Supplied with the Milwaukee MA917B/1 refillable glass pH electrode and MA831R stainless steel temperature probe, the MW150 MAX is ready for precision pH analysis right out of the box.
Measure pH, ORP & Temperature with Laboratory Accuracy
The MW150 MAX combines three essential laboratory measurements into one professional bench meter.
pH Measurement
Measure pH from -2.00 to 20.00 with outstanding ±0.01 pH accuracy, making the meter suitable for analytical, industrial, and research applications.
ORP Measurement
Measure oxidation-reduction potential from ±2000 mV for monitoring oxidation, disinfection, and chemical treatment processes. (ORP electrode sold separately.)
Temperature Measurement
Measure temperatures from -20.0 to 120.0°C (-4.0 to 248.0°F) using the included stainless steel temperature probe while automatically compensating pH measurements for improved accuracy.

Probe Care & Maintenance
Proper electrode maintenance ensures accurate measurements and extends probe life.
Storage
Store the pH electrode in Milwaukee MA9015 Storage Solution. Never store the probe in distilled or reverse osmosis water, as this can permanently reduce electrode sensitivity.
Cleaning
Regularly soak the electrode in Milwaukee MA9016 Cleaning Solution for approximately 20 minutes to remove sample residue and prevent junction clogging.
Routine Inspection
Inspect the electrode for:
- Glass damage
- Cable wear
- Clean, dry connectors
- Salt deposits (rinse away with clean water)
Calibration
For maximum accuracy, calibrate:
- Before critical measurements
- After cleaning
- Following long-term storage
- Whenever measurement accuracy is in doubt
Milwaukee recommends:
- MA9004 pH 4.01 Buffer
- MA9007 pH 7.01 Buffer
- MA9010 pH 10.01 Buffer (for three-point calibration)
- MA9015 Storage Solution
- MA9016 Cleaning Solution
The Milwaukee pH-START Kit conveniently includes the most commonly used calibration, cleaning, and storage solutions.
