MAX pH/EC/Temp Monitor

Features:Fast easy to read current results with 3 large digital BACKLIT LCD readouts.Accurate to +/-0.2 pH (0.0 pH to 12.0 pH).Accurate +/-2% Full Scale EC. External Switch atop the unit converts EC conductivity to EC using 0.5 or 0.7 conversion factor.Simple two-point pH calibration and one point EC, for increased accuracy with manual trimmers for easy adjustment.Gel-filled, double junction MA911B/2 (included) lab grade pH electrode for low maintenance and high performance.6.5 feet probe cables for extra flexibility when testing.12 VDC power supply.ACCURACYThe Milwaukee MAX Monitor offers an accuracy to +/- 0.2 pH with two point manual calibration, EC accuracy of +/-2% Full Scale and +/-0.5 deg F (0.3 deg C) temperature accuracy.AUTOMATIONJust calibrate the parameters and begin to monitor 24/7!EASY INSTALLATIONThe MC811 MAX pH/EC/Temp Monitor comes with a complete mounting kit including a probe holder.SENSING BULBThe glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.REFERENCE JUNCTIONThe 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.STORAGEThe 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 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 calibiration 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.CLEANINGResidue 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 orga-nic material. We recommend regularly soaking your electrode in cleaning solution.CALIBRATIONThe pH sensing bulbs become less sensitive over time so make sure that you are calibrating reguarly to keep your PRO pH controller accurate. Also, calibrate after cleaning or a long period of storage.
