Rated 4 out of 5 by from Different Maybe it's me but I think that in past the wires were stripped and welded closer, shorter than these. Still, better with these fine wires than I could manage with some "DIY" arc welder thing. (And much preferred the wallet-style carrier and wax-paper bags as opposed to the box and plastic bags.)

Rated 5 out of 5 by from Excellent product. I purchased these thermocouples for use in measuring the temperature of electronic components on Printed Circuit Board assemblies during testing. They are exactly as advertised, reasonably priced and ideal for this application. I will continue to use them in the future.

Rated 5 out of 5 by from Ready made for ease of use I purchased these thermocouples because they came already cut to length and beaded. It has saved me time in setting up configurations and simplified my job.

Rated 4 out of 5 by from Good product, good value These work very well, but I had to call Omega to find out the polarity of the wires. The Kapton coating isn't marked. The bag was marked Negative:red/shorter, but that wasn't correct.
