Holds up to elevated temperatures
Purchased this wire about three weeks ago for an upcoming U.L. test. Insulation held up very well to temperatures of 600 to 800°F. I thought the test conditions, heat/grease/mechanical abuse, would destroy the thermocouples and that they would need to be replaced for each test run. I was wrong. They survived several test runs and are still usable.

Sturdy Extension Wire
The wire was very solid which worked well for durability purposes. This feature made it difficult to properly connect the wire to miniature k-type connectors.

A bit overpriced....
A bit overpriced for the quality of the wire. It was not an easy product to work with.

Hi, Is the wire compatible with organic/week acidic solution of chemical reaction to measure the temperature of the solution?
Hi Pawan,
The thermocouple alloys may contaminate your process. For this I would recommend HSTC series; hermetically sealed in PFA thermocouples.

Hi, what would be the most sutable type of thermocouple wire to be used for measuring a temperature around -5c to +5c ? I was planning to use the HH-25U or HH12C readout. Is Type T is more accurate than K or J for example?.
Thank you for your inquiry. At low temperatures, Type T is the most accurate of all thermocouple types.

Hi I am looking at purchasing a spool of TT-K-24-500 and I need it calibrated How do I go about doing this?
Hello,
If you need the wire with a calibration certificate you can order as part number TT-K-24-500-CAL-3.

What's the minimum bend radius?
Thank you for the inquiry. Please allow for 5 to 7 diameters of the wire (narrow side dimension).

Hi, Is compatible with OM-CP-OCTTEMP-A? Regards
Hi, thank you for your question. OM-CP-OCTTEMP-A if definitely compatible with type K thermocouples. If you are making your own thermocouples with this wire, please remember to use miniature connectors (like SMPW-K-M) to plug directly into your logger.

How many times it can be used at average temp around 750 °C with insulation of nextel cermaic ? Is it (nextel cermaic) flexible enough to bend & what are effects of high temp around 1000 °C on it?
Thank you for the inquiry. This product has Nextel ceramic fiber which is not suitable for bending applications. The ceramic fibers used in the material become brittle after exposure to high temps. If you must use this material for bending app please consider the following with Inconel overbraid which keeps the fibers in place.
