The Milwaukee MW101 PRO pH meter has won fans around the world with its reliable, fast operation as well as its rugged design and accuracy. WHAT PEOPLE ARE SAYING "This is an awesome pH meter!" "I love this little meter." "Rugged portable meter, calibrates easily with pH 4, 7 and 10 buffers, readings dead on." SUMMARY The Milwaukee MW101 PRO pH meter has won fans around the world with its reliable, fast and simple operation as well as its toughness and accuracy. The Milwaukee PRO pH Meter is preferred by people testing samples that cause other pH testers and meters to fail from brewers and wine makers to hydroponic growers and farmers. The Milwaukee PRO pH meter offers: SPEED The MW101 delivers fast results to ±0.02 pH accuracy with two point calibration. TOUGHNESS The rugged meter is designed to take knocks. Paired with low maintenance, lab grade SE220 double junction, gel filled electrode, the MW101 is ideal for everyone from educators and pool professionals to brewers and growers. DESIGN FEATURES Fast easy to read results with large digital LCD readout. Accurate to ±0.02 pH with a 0.00-14.00 pH range. Lightweight and portable. Easy measurement: just place the probe in the sample, gently stir and wait for the reading to stabilize Simple manual two-point calibration for increased accuracy. Gel-filled, double junction lab grade pH electrode for low maintenance and high performance with a screw on cap to ensure proper storage (SE220 probe included). 3 feet probe cables for extra flexibility when testing. Auto shut off and low power demand for approx. 300 hours of continuous use. (battery included) USE AND CARE pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction. SENSING BULB The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes. REFERENCE JUNCTION The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function. You can extend the life of your pH electrode in the following ways. CLEANING AND STORAGE All pH 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 codes MA9015 and MA9016 at checkout time! This will be needed to help clean and condition the pH electrode before use! STORAGE The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged. Storing in pH probe storage solution MA9015 or pH calibration buffers will help address both these issues. Do not store in tap water and DI water. This will damage the sensitivity of the probe. The best way to store the probe is with the probe's cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage. CLEANING Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution MA9016. CALIBRATION The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO pH meter accurate. Also, calibrate after cleaning or a long period of storage.
