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. See the Related Links section at the bottom of this page for addtional models. |  |

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.

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.

I need a probe and connector I can insert in a campfire up to 800 degrees C with the meter 2-3 ft from the fire. Do you have a product that can do this?
Thank you for your inquiry. The KQXL-116U-6 can measure the temperature of the air above the campfire but not the fire itself. Heat sources can cause damage to the probes when exposed to it. Additionally, only the metal probe is rated for temperatures up to 800 C, the connector cannot be exposed to that temperature. It's only rated up to 180 C. If you have any further questions, please call 1-888-826-6342, ask for Temperature Engineering and speak to one of our temperature engineers over the phone.

Hi! Is this thermocouple (KQXL-18U-18) bendable?
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
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.
Thank you for your inquiry. Unfortunately we do not have a high temperature connector that can physically withstand 1150C.

Would the KQXL-14U-12 be able to be inserted directly into a pipe that water runs through? Or would it be recommended that it be installed in a thermowell?
The probe can be installed directly in flow but if there is any significant velocity to the flow it is not recommended. Care must be taken to ensure the flow isn't capable of shearing the probe off especially if it is extended 12" into it..
