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.

    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
    Resistivity: 2 to 20 M?-cm
    TDS: 0 to 35.0 g/L
    Salinity: 0 to 25.0 ppt
    Temperature: 0 to 50°C (32 to 122°F)
    Conductivity/Resistivity: ±1.0% full scale temperature; ±0.5°C
ATC Range: 0 to 50°C (32 to 122°F)
Calibration: One-point calibration (1413µ S/cm)
Power: Two (2) CR2032 3V lithium ion batteries (included)
IP Standard: Waterproof and dustproof meets NEMA 6 (IP57) standard
Auto Power Off: After 10 minutes (override available)
    Meter: 148 L × 29 W × 14 mm D (5.82 x 1.14 x 0.55")
    Carrying Case: 168 L × 96 W × 28 mm D (6.61 x 3.78 x 1.10")
Weight with Case: 178 g (6.28 oz)

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.

Is your unit sufficient for testing DI water

Asked by: QM Mgr
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?

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.
