PRO 2-in-1 (pH & Temp) Waterproof Testers with ATC
Manufacturer: Milwaukee Instruments
Description
The Milwaukee PH55 and PH56 PRO Waterproof 2-in-1 pH/Temp Testers deliver reliable, accurate pH and temperature measurement in a lightweight 3.5-ounce IP65-rated design built for everyday use across aquariums, hydroponics, horticulture, pools, brewing, education, and many other applications. Both testers feature gel-filled double junction replaceable electrodes, automatic temperature compensation (ATC), large dual-level LCD displays with stability indicators, and automatic 1 or 2-point calibration. The PH56 offers improved accuracy and more saved calibration points over the PH55, along with an exposed temperature probe positioned close to the pH probe for faster thermal response.
Features:
- PH55: 2-in-1 pH/temp tester; range -2.0 to 16.0 pH; accuracy ±0.1 pH, ±0.5°C; resolution 0.1 pH; 2 sets of pre-memorized buffers (pH 4.01/7.01/10.01 or 4.01/6.86/9.18); replaceable MI56P electrode; approx. 300-hour battery life
- PH56: 2-in-1 pH/temp tester; range -2.00 to 16.00 pH; improved accuracy to ±0.05 pH, ±0.5°C; 6 saved calibration points; exposed temperature probe for fast ATC response; stability indicator and hold function; replaceable MI56P electrode; approx. 300-hour battery life
- Both models fully waterproof to IP65 with rugged construction designed for daily use
- Gel-filled double junction pH electrodes on both models for low maintenance and extended probe life
- Automatic Temperature Compensation (ATC) on both models
- Large dual-level LCD display for fast, easy-to-read results
- Lightweight and portable at just 3.5 ounces — up to half the weight of comparable testers
- Auto shut-off with low power demand for extended battery life
- Store pH probe upright in storage solution MA9015; never store in distilled or RO water; clean regularly with MA9016 cleaning solution; calibrate after cleaning or storage
