Milwaukee MW103 PRO+ Portable 2-in-1 pH/pHmV/Temperature Meter
Reliable pH measurement depends on more than the number shown on the display – it also depends on how well the pH electrode itself is responding. The Milwaukee MW103 PRO+ is designed to give users a clearer picture of both.
Alongside accurate pH and temperature measurement, the MW103 PRO+ features a dedicated pHmV mode for evaluating pH electrode offset and slope. By checking the electrode response in fresh calibration buffers, users can gain valuable information about electrode condition that a successful calibration alone may not reveal.
Go beyond successful calibration
In pHmV mode, the electrode response can be checked at pH 7.01 to evaluate its offset, then compared with a second buffer such as pH 4.01 or pH 10.01 to evaluate its slope. This provides an additional way to identify signs of electrode aging, contamination, poor hydration, or deteriorating response.
The MW103 PRO+ is a practical choice for professional and educational pH measurement across laboratory work, water quality testing, food and beverage production, brewing, winemaking, hydroponics, horticulture, aquariums, environmental testing, and other applications where dependable pH results and electrode performance matter.
Milwaukee EC45 PRO EC/TDS/CF Nutrient Stick Meter
Maintaining the correct nutrient concentration is one of the most critical factors in successful plant growth. In hydroponics, greenhouse cultivation, and fertigation systems, even small fluctuations in electrical conductivity (EC) can lead to nutrient lockout, deficiencies, or wasted fertilizer. The Milwaukee EC45 PRO Nutrient Stick Meter is designed to make nutrient monitoring fast, intuitive, and reliable – right where it matters most.
Milwaukee MI0041 Magnetic Stirrer (220/240V) – Compact, Reliable Mixing for Everyday Lab Work
When you’re preparing buffers, dissolving powders, mixing reagents, or keeping solutions homogeneous during testing, consistent stirring is the difference between repeatable results and wasted time. The Milwaukee MI0041 Magnetic Stirrer is built for practical, daily mixing tasks in labs, classrooms, and quality-control environments – where you want simple operation, steady performance, and a small footprint.
Most common, high-utility uses for the MI0041 include:
- Laboratory & Quality Control
- Education & Training
- Water & Environmental Testing Workflows
- Light Industrial / Process Support (Bench Use)
