Milwaukee MW180 MAX pH/mV/EC/TDS/NaCl/Temp Bench Meter with Logging

The Milwaukee MW180 5-in-1 MAX pH/ORP/EC/TDS/NaCl/Temp. Logging Bench Meter is fast, reliable, simple to operate, and is designed with a small lab space footprint.  It is ideal for use by horticulture, labs, food processing, water treatment, education and many other applications with challenging pH/ORP/EC/TDS/NaCl/Temp. measurement needs.

With easy 1-point EC/NaCl and up to 3-point pH calibration, 7 memorized standard pH buffer choices, 6 memorized EC calibration solutions, and 2-point temperature calibration, the meter can be quickly calibrated to a higher temperature accuracy compared to other meters.  It also provides a more accurate temperature compensation readings than a 1-point calibration.  The MW180 5-in-1 MAX Bench Meter is accurate to ± 1% of reading for EC/TDS and NaCL. 

The meter comes with a MA814DB/1 (4 ring) conductivity probe, lab grade MA917B/1 pH electrode and temperature sensor MA831R, allowing the meter to automatically adjust the pH/ORP/EC/TDS/NaCl reading for the effect of temperature (ATC).

CARE AND USE

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, simply slide the plastic shield off and clean with DI water and soft cloth. For pH, simply soak the pH electrode in MA9016 cleaning solution.

The life of your meter can also be extended in the following ways:

Storage - When not in use, store the meter and EC probe in a safe area to avoid damage. The EC probe is stored dry. The pH probe should be stored wet with MA9015 storage solution to keep the bulb moist during non-use times for best performance and life duration.

Calibration - The MW180 MAX is easy 1-point EC/TDS/NaCl calibration for ease-of-use, up to 3-point pH calibration and 2-point temperature calibration for best accuracy in (ATC).  Calibrating regularly is the best way to keep the meter readings accurate.
