Milwaukee MAX Waterproof 3-in-1 pH/ORP/Temp Tester with Replaceable Probe - PH58

DESIGN FEATURES

• Fast easy to read results with large digital LCD readout.
• Extreme pH accuracy to  ±0.05 pH and +/- 2 mV with an extended pH range (-2.0 pH to 16.0 pH).
• Extended Resolution to 0.01 pH.
• Lightweight and portable.
• Easy measurement: just place the probe in the sample, gently stir, wait for the stability indication to show a stable reading and then freeze the reading.
• Simple Automatic one or two-point calibration.
• 2 Sets of pre-memorized buffers.
• Gel-filled, double junction pH electrode for low maintenance and high performance.
• Over 250 hours of battery life (batteries included).
• Fully waterproof to IP65.
• Replaceable pH electrode Mi58P.

CARE AND USE

All pH/ORP sensors have a limited life and response time gets longer with age. Properly maintaining your pH pen tester will give you fast, accurate results for longer. So, be sure to order the Milwaukee pH Maitenance Kit code PH-Main at checkout time!  This will be needed to help clean and condition the pH electrode before use!

Here are our top four tips.
1. Always store with the cap full of buffer or storage solution MA9015 not water.
2. Clean your Tester regularly by soaking in cleaning solution MA9016.
3. Calibrate after cleaning and/or storage before testing to adjust for changes in the pH sensor.
4. Gently stir the Tester in the sample for a faster result.
