Date published: 2022-10-14
Rated 5 out of 5 by from Good tc wire These K thermocouples are different than pictured. They are a parallel rip design (no external jacket). The insulation is yellow and one side has a red stripe. They strip easily. If you are pulling wire through conduit get a jacketed design but if you meter is nearby the UUT then I recommend these. They are very easy to work with. I've also bought these in T thermocouples in the past. They are the same except the insulation is blue.

Rated 3 out of 5 by from Great customer service Great customer service from Omega. The insulation is not particularly abrasion resistant and hard to get a clean cut when stripping the wire ends. That said, this is the wire I required for my installation.

Rated 5 out of 5 by from Thermocouple Wire This wire was exactly as advertised. The wire is very stiff, but is to be expected. Had a little difficulty stripping the wire.

Rated 5 out of 5 by from Will purchase again This product came quickly and was exactly as expected! Great quality wire that works as described, and the spool it comes in makes storage really easy and compact. This stuff is also seemingly indestructible which I love!
Date published: 2020-07-08
Rated 5 out of 5 by from Exactly as advertised. Exactly as advertised. The insulation is a little tricky to strip, but that is expected with the high temperature rating. The wire is very stiff as well, which makes it a little more difficult to work with when routing wiring.

Rated 5 out of 5 by from Superior Tolerance and Corrosion Resistance I have been using this K-Type thermocouple wire in my R&D Engineering Lab for over 6 years. I am slowly replacing old J-Type wire with this K-Type wire as the J-Type is showing corrosion in areas where moisture is more prevalent. Since we build humidifiers in the lab, resistance to corrosion is key. And, this K-Type wire has shown zero signs of corrosion because of the bi-metals used. It is very easy to order online with Omega and their e-commerce interface is easy to use and simple to compare specs with other available products. They're telephone customer service is superior as well. I have always got the technical support I need, and quickly.

Rated 5 out of 5 by from Great cable I think that there are just a couple of companies that make good thermocouple wire and Omega is one of, if not, the best of the market.

Rated 5 out of 5 by from Works Well We use this in our kiln to heat treat lumber for pest control. I bought the solid wire due to its higher temperature rating but I wish I could get it in a stranded.

Rated 4 out of 5 by from Just what I needed. This wire was recommended in the Garmin Installation Manual that I am using to install a G3X Touch EFIS system. Exactly what I needed.

How can we strip the wires of GG-K-24S-1000? Is there any particular tool/stripping procedure available? My customer is using the normal wire stripper and the insulation also come off.

Asked by: RAJNe
Thank you for your inquiry. You will need to use a thermal wire stripper to remove insulation properly.

Is GG-K-20S-50 RoHS-compliant?

Asked by: Hanistor
Hello, If the wire was ordered as GG-K-20S-50 then it will not be ROHS compliant. If ordered as GG-K-20S-50-ROHS then it would be made ROHS compliant.

On the table inside the specs of this thermocouple, there's a column "Nominal Size". What are the units of that column? millimeters? inches?

Asked by: fzigunov
Thank you for your inquiry fzigunov. The unit of the Nominal Size column is inches.
