Product Specs

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.

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?

Asked by: Maywu
Thank you for your inquiry about the handheld meter. Yes, this is correct for the accuracy.

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?

Asked by: Anonymous
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.

Do you sell a meter that can read 500 ohms to 20 Megohms?

Asked by: Satch
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?

My sample I need to test, should I dilute it? The product is 'syrup' thick.

Asked by: AnnaLynne
Thank you for your inquiry. Please contact our Flow Engineering department with this request as they will need some more information about your application before advising whether dilution is necessary. You can email them at flow@omega.com.

Hi! Is the minimum resistivity 2 ohms or 2M ohms?

Asked by: SHERRI
Hi, Thank you for your question. The minimum resistivity is 2 M ohms.
