Milwaukee MW302 LED Economy Portable Conductivity EC Meter with 1 Point Manual Calibration, 0 to 10.00 milliSiemens/cm, 0.1 milliSiemens/cm Resolution, 2 percent Accuracy

Works great!

product did not work. Myself, as well as many others tried calibrating it, and still didn’t work.

Very good build quality, range, resolution and accuracy. Being factory calibrated, I still perform a cal check routinely and find it dead-on accurate for 222mV standard.The display is large, clear and easy to read.Regarding another reviewer who marked the meter down due to salt residue on the probe - that salt is Potassium Chloride, which is the storage solution for the probe. As KCl dries out, it becomes a white salt. Simply rinse with water to remove.

Hi received this item today and it have this white residue on the probe! Is this worth it keep? or needs replacing as it would affects device life span? any help is appreciated thank you

The meter works fine. I've checked different fluids and I'm getting positive and negative readings. I used alkaline water to test for the negative readings. One reading was -599. The meter comes with a bottle of storage fluid, but I brought more as well. It comes with the probe, but it's not shown in the picture. It comes with a 9 volt battery too.

There was a crystallized residue on what I thought was a brand new device! It looked to have been broken. I wasn’t happy when I received it!

Great product was ready to use right out of the box. Even came with a battery.

I would definitely spend the couple of extra bucks and step up to the non economy one next time (MW802). This one only reads PPM to about 1800 or so, then it reads and error message. Other wise it's a great little meter.
