Additional Features
The CL3515R is a portable calibrator/thermometer with a 4-digit LCD. It is designed to use external K/J/T/E/R/S/N/L/U/B/C type thermocouples as temperature sensors. OMEGA™ offers a complete selection of thermocouples, or we can custom-design parts to meet your specifications. The thermometer features a dual thermocouple input and an adjustable thermocouple offset. The thermocouple types comply with the NIST monograph 175, revised to ITS-90 standards.

Can I communicate with the unit through USB in my own program instead of the windows program. I am trying to use it under Mac so would like to open it as a serial port to control it. Is there any documents of Remote Programming Commands for the CL3515R?
Hi Apple
We do have command protocol for the CL3515R. Please email Temp@omega.com to request copy.
Best regards

What is the expanded uncertainty considering k=2 in degree C for the ranges of 0-100, 100-200, 200-300 and 300-400 degrees, thermoucouple type J. I could not find the information over the manual.
Hi MB0723,
Thank you for the inquiry. This product is provided with stated accuracies only. Uncertainties are not provided unfortunately.

Since most modern computers don't have disc drives, where can I download the software? I don't see it on the website.
Scroll to the bottom of the page. Under "Quick Links", there is a section called "Software". That will take you to Omega's web page containing all of their software. For this specific item, click on "Temperature", then find this model number on the FTP site.

Can this unit be used to calibrate heat controllers? I cannot see the receptacles or this information within the description.
Thank you for the inquiry. As long as the meter or controller is using the same thermocouple type as the controller, then the CL3515R can be used to verify the accuracy of the thermocouple reading.
Best regards

I am having an issue getting the software to see the calibrator. When I plug it in and try to select a port it does not pull up an option to click anything. Any suggestions? Also is there any more information on how to calibrate than what's in the manual?
Please make sure you are selecting Run As Administrator to install the USB driver. Check the Device Manager to confirm the USB driver is correctly loaded and Windows assign a port number.

Does this unit come with the optical to USB interface cable, if not what is the P/N for the cable?
Thanks for connecting with Omega. The product manager has confirmed that this product does come with a USB cable.

What is the refresh rate?
Hi Gior,
Thank you for the inquiry. Refresh rate is once per second.
Best regards

Does Omega offer a calibration/re-certification service for the CL3515R, and what is the suggested frequency of recalibration?
The CL3515R can be re-calibrated and it is recommended it be done once per year. This can be set up by the Customer Service group when you are ready to move forward.
