Extech EC100 Water Quality Meters-Conductivity / Salinity

Recommend to a Friend

Used it to cross-check the Pro instrument!

5.0

I own several $10 pocket conductivity meters and have verified that all are junk. I do regular water quality monitoring using a YSS-DSSPro. Earlier this year that instrument was grossly-miscalibrated. Wanting my own good meter to measure salt contamination, I picked up the EC100. Out of the box the calibration was very close but I tweaked it in on 1000 µS/cm solution, then verified linearity on two other cal solutions. I spent the weekend taking readings with the YSI meter and compared it to the EC100. Finally we have confidence that the expensive meter is correct! And the post-test cal check showed the EC100 was still spot-on. It also makes a nice pocket thermometer. This is an excellent little meter at a fair price.
