Logging Bench Meter has won fans around the world with its reliable, fast and simple operation as well as its tough, sleek design and small benchtop footprint. It is accurate to ± 1% of reading for EC/TDS/NaCl and up to +/-0.002 pH, with automatic or manual temperature compensation and a built in dedicated GLP key. Ideal for use by education, horticulture, labs, food processing, water treatment and many other applications with challenging pH/ORP/EC/TDS/NaCl/Temp. measurement needs.The Milwaukee MW180 5-in-1 MAX pH/ORP/EC/TDS/NaCl/Temp. Bench Logging Meter is preferred by people testing samples in various applications. The easy-to-use logging feature allows data collection without messy notes and errors. From aquaculture, environmental, research to educators, the MI180 MAX is your cost effective meter for fast, accurate readings.People choose the MW180 5-in-1 MAX pH/ORP/EC/TDS/NaCl/Temp. Bench Logging Meter to improve the accuracy and efficiency of their testing program. With easy 1 point EC/NaCl and up to 3 point pH calibration, 7 memorized standard pH buffer choices, 6 memorized EC calibration solutions 2 point temperature calibration, the meter can be quickly calibrated to a higher temperature accuracy compared to other meters and it provides more accurate temperature compensation readings than a one point calibration. The MW180 5-in-1 MAX Bench Meter is accurate to ± 1% of reading for EC/TDS and NaCL.The MW180 MAX pH/ORP/EC/TDS/NaCl/Temp. Bench Logging Meter comes with the Milwaukee MA814DB/1 combination EC sensor and MA917B/1 pH electrode. They are Milwaukee's top selling lab grade EC and pH probes for a reason. Designed to be both low maintenance and able to withstand more challenging samples. The MA814DB/1 and MA917B/1 are ideal for use in horticulture, aquaculture, environmental labs, water treatment/conditioning and many other applications.The MW180 MAX is easy 1 point EC/TDS/NaCl calibration for ease-of-use, up to 3 point pH calibration and two point temperature calibration for best accuracy in (ATC). Calibrating regularly is best to keep your MI180 5-in-1 MAX Bench meter accurate for all your readings.pH/EC/TDS meters usually start performing poorly because of problems with the sediment on the conductivity probe's rings or build up on the glass pH bulb. The dirt on the EC probe rings or on the ph bulb can change impedance. Cleaning the rings is simple. Slide the plastic shield off and clean with DI water and soft cloth to keep your readings accurate. For pH, simply soak the pH electrode in MA9016 cleaning solution.
