The Milwaukee PRO EC/TDS/NaCl/Temp. meter offers:

Accuracy

People choose the MW306 4-in-1 PRO EC/TDS/NaCl/Temp Portable Logging Meter to improve the accuracy of their testing program. With easy one point calibration and six standard buffer calibrations choices, the meter can be quickly calibrated to a high accuracy compared to other meters and it provides highly accurate temperature compensation readings. The MW306 meter is accurate to ± 1% of reading for EC/TDS and NaCL. 

The meter comes with MA815D/1 conductivity probe with a built in temperature sensor allowing the meter to automatically adjust the EC/TD/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 is IP67 Waterproof rated.

Low maintenace

The MW306 PRO EC/TDS/NaCl/Temp Portable Logging Meter comes with the Milwaukee amplified MA815D/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 MA815D/1 is ideal for use in hydroponics, horticulture, aquaculture, labs, water treatment/conditioning and many other applications.

• Internal clock date to keep track of different time-dependent functions (calibration, timestamp,calibration time out).
• 3 feet probe cables for extra flexibility when testing.

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. Remove batteries if not in use for a prolonged period to prevent battery compartment corrosion.

Calibration

The MW306 is easy 1 point calibration for ease-of-use and high accuracy with built in (ATC) feature.  Calibrating regularly is best to keep your PRO MW306 4-in-1  meter accurate for all your readings.
