Milwaukee MW302 PRO High Range EC Conductivity Meter – Complete Bundle with Hard Carrying Case
Get lab-grade electrical conductivity measurements in the field with the Milwaukee MW302 PRO EC Meter. Engineered for the demanding environments of hydroponics, agriculture, food processing, water treatment, and laboratory use, the MW302 delivers fast, accurate readings from 0.0 to 10.0 mS/cm with automatic temperature compensation (ATC) — no manual adjustments needed.
This bundle includes everything you need out of the box: the MW302 meter, SE520 conductivity probe, starter calibration solution, and the rugged Milwaukee MI0028 hard carrying case — a $40+ value included at no extra cost.
Why EC Measurement Matters
Electrical conductivity (EC) is the go-to metric for optimizing nutrient delivery in hydroponics, verifying fertilizer effectiveness in soil agriculture, and monitoring dissolved solids in water treatment and food production. The MW302 gives you the precision to act on that data confidently.
