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.

OK Quality 2 channel calibrated unitWe bought this because it is calibrated. Seems susceptible to EMI. The HVAC system combined with other adjacent CE compliant test equipment cause this to fail the self test. Other thermometers and test equipment do not fail under the same conditions. It is good that it reports the errors, but it would be nice if it was more robust. Good tech support to identify EMI as the cause.

Impressive AccuracyI have purchased 3 of these over the past couple of years for training customers on properly performing SAT's and they work great. They are every bi as accurate as $2,000 calibrators we have used in the past and they handle a wide range of thermocouples.

Rarely in specificationAlways having to adjust and issuing out of tolerances. Get what you pay for, buy a Fluke.

Meets my needsI still have a lot to learn about all the capabilities of this equipment, but it works for my calibration needs. I would like to see more documentation on the capabilities and how to use them. What I have seen thus far is a bit lacking for me. I haven't had the opportunity to play with it outside of performing my calibrations. However, it is great for my calibration needs
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.

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.

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

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?
