Super OMEGACLAD™ XL Probes are an excellent choice for high temperature measurement. They provide very low drift at high temperatures as compared to conventional Inconel and Stainless Steel sheathed probes. They are available in both K and N thermocouple calibrations. Omega offers probes in a variety of styles.

Probes up to 48 inches in length are shipped "straight." Probes over 48 inches are shipped "coiled". If probe above 48 inches in length must ship straight, please add "-SST" to the end of the part number, and add $75.00 to the probe cost. Additional shipping fees from carrier may also apply for non-standard length packaging.

Rated 5 out of 5 by from Chief artist Works like a dream. I didnt know the other probe was bad until it was too late.

Rated 5 out of 5 by from Machined Beautifully This temperature probe I purchased will be used for measurement of gas temperatures up to 2100 deg. F (although generally much lower). It was delivered precisely as described and it will be used to collect data for EPA air emission tests at industrial facilities. I am very pleased with the quality of this temperature sensing Type K probe.

Hi! Is this thermocouple (KQXL-18U-18) bendable?

Asked by: milankovich
Hi Milan, Yes, thermocouples can have a bend radius no less than 3 times it’s diameter. Bending the thermocouple probe will not cause any harm the probe unless it is bent to a point exceeding the limit stated.

How do you test your High temperature Model XL Thermocouples? DO you do it electronically, or do you use a drywell. If you use a drywell do you use ceramic inserts or Inconel or something else? Or do you use a salt or sand bath? Thanks You

Asked by: red pepperhead
Thank you for the inquiry. To provide high temperature calibrations our calibration lab uses a combination of metal alloy well, ceramic well, and salt bath. For more detail please forward request to TEMP@OMEGA.COM. Best regards OMEGA

Is a high temp connector available? temperature exposure up to 1150C.

Asked by: KnewMethod
Thank you for your inquiry. Unfortunately we do not have a high temperature connector that can physically withstand 1150C.
