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.

Can you tell me the diameter of the probe head and the length of the 'neck' of the instrument? I want to know if this probe is suitable for the containers I intend to take measurements in.
Thank you for your inquiry! The diameter of the head is 10mm and the length of the neck is 30mm.

What is the resolution of the resistivity? Does it read at increments of 1 M ohms? 0.5 M ohms? What is the resolution of the conductivity?
In regard to your inquiry, the CDH-93 hand held conductivity tester has a 3 digit display and the resolution will either be 0.1 or 0.01 depending on the microSiemen range.

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

Does this unit require a solution to conduct its single point calibration, if so what solution is required and how can it be purchased? Can this unit be purchased with a NIST traceable calibration certificate for its full resistivity range?
Thank you for your inquiry! Unfortunately, the unit cannot be purchased with a NIST traceable certificate. For the calibration 1413 microsiemens per centimeter solution is used. The part number for this solution is CDSA-1413.

Student is wanting to use to check resistivity and conductivity of De-ionised Water.. is the resolution of this instrument suitable?
Thank you for your inquiry about the conductivity/resistivity meter. It will be able to measure up to 2 MOhm resistance for DI Water.

We have gotten resistivity readings below 2.0 (e.g. 0.5, 0.6, 1.6). Should we interpret those readings as less than 2.0 and not assume they are quantitative? 2. Our meter arrived with liquid in the electrode cap. What liquid should be in the cap?
Thank you for your inquiry. Yes, anything less than 2.0 will not be accurate or be within the accuracy and the storage solution is 3M KCl.

Hi! Is the minimum resistivity 2 ohms or 2M ohms?
Hi,
Thank you for your question.
The minimum resistivity is 2 M ohms.
