Rated 5 out of 5 by from Truly a Rugged Thermocouple Truly a rugged thermocouple. Our testing unit puts these probes through some extreme heat and harsh conditions with exposure to the process. They have not let me down yet!

Rated 5 out of 5 by from Meets our process requirements Product always ships in a timely manner and projected ship dates are met
Date published: 2023-01-16
Rated 4 out of 5 by from Good usability but probe has surface scratches. Good construction overall, and good response measuring water. My only critique is that the probe seems to have very apparent machining/grinding marks on it, perhaps from its manufacturing process. Don't expect it to be glass smooth.
Date published: 2022-10-21
Rated 5 out of 5 by from Well Made TC This is a very well made thermocouple. The sheath is machined to high precision, and the response to temperature change is fairly quick.

Rated 5 out of 5 by from Excellent product Thermocouples work great and are as advetised. We have been purchasing from Omega on and off for many decades as our need for thermocouples is sporadic. But when we need them, we go to Omega.

Rated 4 out of 5 by from Customer service lacking Called customer service and was promptly directed to the website first and then if I have any issues to call back. Product is awesome though.

Rated 5 out of 5 by from Great Temp Sensors! Great, high quality, long lasting K-Type Temp Sensors!
Date published: 2022-01-02
Rated 5 out of 5 by from Great probe for temperature chamber Very easy to set up, the rigidity of the probe allows in to stay it place close to the sample under test but it malleable enough to be bendable by hand. Highly recommend it.
Date published: 2021-03-11
Rated 3 out of 5 by from Functional yes but improvement possibility Ordered a SS k-type first but had some oxidation on probe. Followed up with a CAXL k-type and still have oxidation on probe. Both were used in the same SS protection tube. Ambient is a O2 rich environment using gas heated from 500 to 1700F. Not sure if exotic T/Cs would be a better choice.

Rated 5 out of 5 by from Awesome replacement for mercury thermometers. This probe is amazing! The fact that you can customize the materials and size to your specific needs is wonderful! We will never use mercury thermometers for our distillations again!

Rated 4 out of 5 by from Lab Technician This thermocouple is light and accurate in temperature.
Date published: 2020-05-28
Rated 4 out of 5 by from Technician Thermocouple is very accurate and light so it could be hold by a small clamp. Just make sure that the gauge of the wire is the right size for your project.

can these probes be bent? will bending them effect the readings?

Asked by: Daniel246
Hello and thank you for contacting Omega. Yes, we can confirm that these probes are bendable to 90 degrees and that the bend will not affect the readings. We suggest a bending radius of 0.33” or larger. Please contact our Tech Support if you have any further questions.

How to determine accuracy of TJ36-? Not sure if listed special limits apply. Multiple configs: K or J, 316SS, varied sheath diameter & length, standard wire/length, grounded, SMPW-M, single & dual probes

Asked by: SpecialStandard
Thank you for your inquiry SpecialStandard. The accuracy (tolerance) is determine by the Special Limits of Error according to the ASTM E230-ANSI MC 96.1. Please check the following link in page H-2 for the thermocouple tolerances for each thermocouple: https://assets.omega.com/landing-pages/colorcodes/tc_colorcodes.pdf. The tolerance only applies to probes.

Am I able to install these into an exhaust stream with temperatures up to 1450 F without a thermowell?

Asked by: Nick2020
Hi Nick. That should be no problem although the if you want the added protection a thermowell with a threaded bushing would work.

I am looking at a T-type immersion, 304 SS, 1/8" dia, grounded TC. But looks like it is giving me only 40" cable length option. On picking up a 120" or 240" length it gives error saying compatibility issues. Please advise

While the measurement point measures 1000 degrees, can there be a heat transfer to the transient point? In transient point, are there any protection for this?

Asked by: Guli
Hi Gull, Thank you for this inquiry. There is no protection built in for the transition point. Alternate is to provide enough length for the sheath so that heat transfer across the tubing is small enough to be safe. Best regards OMEGA

Do the ungrounded TCs have any electrical isolation rating?

Asked by: DT27
Thank you for the inquiry. We do not offer an electrical isolation rating for our ungrounded thermocouples. Best regards, OMEGA
