Measurement Type
Supply Power

The CDH-93 resistivity and conductivity meter uses advanced automatic frequency conversion and booster technology to keep the electrode constant the same in different solution strengths. It can meet measuring accuracy in the whole range of this electrode by using only the one-point calibration function. The result is the high performance and the lowest cost.

Rated 4 out of 5 by from Good Tool. Poor instructions. So-so support. This will be a good tool for the intended purposes. It is easy to use and appears accurate and durable, but the documentation that comes with it is very meager. I called with a few questions. One was answered other wasn't. Didn't receive a return call or a response to an online support question submitted as a follow up.

Rated 1 out of 5 by from Nonsensical ranges The advertised range for this probe is 5 uS/cm - 50 mS/cm, which converts to 20 - 20000 Ohm*cm (0.020 - 200 KOhm*cm), yet they claim it has a resistivity range of 0-20 MOhm*cm. This would require conductivity readings to go as low as 0.05 uS/cm. In practice, I can't seem to get a single resistivity reading higher than 3 KOhm*cm. I am working with deionized water that should be around 18 MOhm*cm. This is completely unacceptable equipment for the purposes I needed and if you also need to confirm deionized water purity, do not waste your money on this.

Rated 5 out of 5 by from Wire EDM I use this tester to verify my water conductivity for wire EDM it easy to use and fast
