If you work with reverse osmosis or deionized water in a commercial or laboratory setting, you almost certainly need to own an electrical conductivity meter. A TDS meter would work, but then you would need to do the conversion math every time. An EC meter like the AP-2 with a +/- 2% accuracy rating will give you the exact information you want in the format you need. With a 0-9999 micro-siemen range, this meter will work for almost every water type.
- Measures electrical conductivity and temperature with automatic temperature compensation to give you greater accuracy
- Ultra convenient push button calibration (no tools necessary)
- 0-9999 micro-siemen range for nearly every water condition
- Magnetic body so you can stick it and never lose it
- Genuine OEM Product
