Features
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.

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.

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.

Wire EDM
I use this tester to verify my water conductivity for wire EDM it easy to use and fast

Hi. Our spec for resistivity is 2 M Ohm or greater. My question is, Does the meter just cut off and show no reading below 2MOhm? If it does read anything below 2M, does accuracy stay at 1% of full scale?
Than you your inquiry for this meter. Unfortunately, it will not be able read below 2M Ohm.

Do you sell a meter that can read 500 ohms to 20 Megohms?
Thanks for you question.
Omega doesn't have a product that goes to the ranges you have specified.
please contact the flow department to see if they would have other options?

Conductivity: 5 to 50.0µ S/cm, 50 to 500µ S/cm, 0.5 to 5.00 mS/cm, 5.0 to 50.0 mS/cm. The resolution is ±1% of full scale. Does that mean the accuracy is ±0.01x50mS/cm which is ± 0.5mS/cm?
Thank you for your inquiry about the handheld meter. Yes, this is correct for the accuracy.

Is your unit sufficient for testing DI water
Thank you for your inquiry. It would be advised to email our Flow, Level, and Environmental Group at flow@omega.com for that recommendation.

The range is 2 megaohms to 20 megaohms correct? Do these come with calibration certificates? How long are the calibrations good for and can we send them to you guys to calibrate periodically before calibrations expire? Do you guys sell a standards?
Thank you for your inquiry. Yes the resistivity range is 2 to 20 MΩ-cm. These electrodes are calibrated prior to shipping but calibration certificates are not provided. We can provide a Certificate of Conformance though. Field calibrations should be done at least monthly depending on frequency of use. We do sell calibration buffer solutions for this meter. The part number for the solution is CDSA-1413. For additional inquiries please contact us at flow@omega.com and our pH/Flow engineers will be able to help you.
