OMEGA introduces its Cement-On, fast response Foil Thermocouples for fast surface temperature measurement applications in three convenient styles. Styles 1, 2 are made from 0.005" thermocouple alloy & Style 1- B made by 0.008"  by a special process where the butt welded thermocouple junction  Styles 1, and 2 are flat, extremely low inertia construction and are an ideal means of measuring the temperature of both flat and curved metals, plastic and ceramic surfaces where very fast response is desired.

OMEGA's Cement-On Style 1,1-B and 2 Foil Thermocouples are fabricated from ANSI "Special Limits of Error" grade thermocouple materials in "K", "E" and "T" calibrations and yield accurate temperature indication when used with standard thermocouple instrumentation. Styles 1, 1-B and 2 have the fastest response. Style 3 is an economy version constructed from 0.010" diameter bead welded standard limit of error thermocouple wire. It should be used where extremely fast response is not essential.

Rated 3 out of 5 by from Good, but... Does what they are supposed to. COT-1 However the Small diameter wire is not the best for constant re-use. Stripped wire length not good for the miniature connectors SMPW and HMPW. if you want to use the little rubber grommet that comes with the connectors you will need to re-strip the bare ends. And seeing as the price has gone up. The search is always on for an alternative.

I would appreciate your advice for my project, I need a sensor with high accuracy to be installed on a pipe's surface and put it inside a soil container. the temperature range is going to be between 4 and -20 centigrade. Which product do you recommend?

Asked by: Amir
Thank you for your inquiry. I would recommend the SA2C-K-72.

What is the recommended cement to adhere to surface with max temp of 550 F?

Asked by: jjb2023
Thank you for your inquiry. We do not have any epoxy or cement for a maximum temperature of 550 F. The closest we can provide is the CC HIGH TEMP for a maximum temperature of 843 C. Here is the link:

What is the service life of these installed thermocouples on an unused part?

Asked by: Nate K
Thank you for your inquiry. Unfortunately we do not have any life cycle or time before failure data for these products. We cannot provide any signed documentation for these products lifespan since the lifespan is based entirely on the application and/or environmental conditions it is stored in.

We have an application where the surface temperature will reach about 1250 Deg C , The Duration of test 25 Sec to 130Sec. Please confirm whether we can use CO1-K-B or CO2-K or any other suitable

Asked by: srini
The CO1-K-B and the CO2-K are not suitable for use above 370C or 650C respectively. You should look at IR as a possible solution and contact the Temperature Engineers at

Cement on type CO2-K thermocouple with 6" leads,.... What is the best way to extend those leads to wire, then to connector..... do you have instruction on how to do this? Or do you sell a connector for this?....

Asked by: PB N J
Thank you for your inquiry. Using terminal blocks with extension wire and connectors would be the recommended option. Here is a link to our terminal block:
