Logging Portable Meter has won fans around the world with its reliable, fast and simple operation as well as its toughness and IP67 Waterproof rating. Accurate to ± 0.002 pH with automatic or manual temperature compensation, and built in GLP key. Ideal for use by brewers, wine makers, growers, labs, food processing, water treatment and many other applications with challenging pH measurement needs.The Milwaukee MW106 MAX Waterproof 3-in-1 pH/ORP/Temp Portable Logging Meter is preferred by people testing samples in viscus applications that cause other pH testers and meters to fail. The easy-to-use logging feature allows data collection without messy notes and errors. From brewers and wine makers to hydroponic growers and farmers the MW106 MAX is your meter for fast, accurate readings.People choose the MW106 MAX Waterproof 3-in-1 pH/ORP/Temp Portable Logging Meter to improve the accuracy of their testing program. With up to 5 point calibration and 7 standard buffer choices (and two custom), the meter can be quickly calibrated to a higher accuracy compared with one or two point calibration. The MW106 MAX meter is accurate to ± 0.002 pH. 8x more accurate than some alternative meters.The meter comes with an amplified, combination pH probe with a built in temperature sensor allowing the meter to automatically adjust the pH reading for the effect of temperature (ATC).The meter can also be used as a very accurate thermometer with accuracy +/-0.5°C (+/-1°F)The rugged meter is built to take knocks and is IP67 Waterproof rated.The MW106 MAX Waterproof pH/OPR/Temp Portable Logging Meter comes with the Milwaukee amplified MA906BR/1 combination pH/Temp sensor. This is Milwaukee's top selling field grade electrode with lab grade performance for a reason. Designed to be both low maintenance (gel filled) and able to withstand more challenging samples (double junction). The MA906BR/1 is ideal for use in beer making, winemaking and hydroponics and many other applications. 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.The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.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 electrode will no longer function.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.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 material.recommend regularly soaking your electrode in cleaning solution MA9016.The pH sensing bulbs become less sensitive over time so make sure that are calibrating regularly to keep your PRO Plus pH meter accurate. Also, calibrate after cleaning or a long period of storage.
