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.

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.
