The MW170 4-in-1 MAX EC/TDS/NaCl/Temp. 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 & Salinity with automatic, manual or no 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 EC/TDS/NaCL/Temp. measurement needs.

The MW170 4-in-1 MAX 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 MW170 MAX is your meter for fast, accurate readings.


Lab grade. High performance. Automated. Tough.

Accuracy

People choose the MW170 4-in-1 MAX EC/TDS/NaCl/Temp Bench Logging Meter to improve the accuracy of their testing program. With easy 1 point EC calibration, 6 standard buffer choices and 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 MW170 MAX Bench Meter is accurate to ± 1% of reading for EC/TDS and NaCL.

The meter comes with MA814DB/1 (4 ring) conductivity probe with a built in temperature sensor allowing the meter to automatically adjust the EC/TDS/NaCl reading for the effect of temperature (ATC).

The meter can also be used as a very accurate thermometer with accuracy +/-0.5°C (+/-0.9°F)

Toughness

The rugged meter is built to take knocks and has a sleek design that includes a small benchtop footprint.

Low maintenance

The MW170 MAX EC/TDS/NaCl/Temp Bench Logging Meter comes with the Milwaukee MA814DB/1 combination EC/Temp sensor. This is Milwaukee's top selling lab grade EC probe for a reason. Designed to be both low maintenance and able to withstand more challenging samples. The MA814DB/1 is ideal for use in horticulture, aquaculture, environmental labs, water treatment/conditioning and many other applications.

  • Includes MA9315 electrode holder, cables, adapter and probe.

 

CARE, USE AND CLEANING

EC meters usually start performing poorly because of problems with the sediment on the conductivity probe's rings. The dirty rings on the probe 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.

Storage

When not in use, store the meter and probe in a safe area to avoid damage. The EC probe is stored dry.

Calibration

The MW170 MAX is easy 1 point EC/TDS/NaCl calibration for ease-of-use and two point temperature calibration for best accuracy in (ATC).  Calibrating regularly is best to keep your PRO MW170 4-in-1 MAX Bench meter accurate for all your readings.
