Solid thermocouple
So far so good with this thermocouple. One recommendation I do have, double/triple check the connector before ordering. I thought I ordered the right one, but ended up having to order a replacement. Top to Omega, add images of the termination chosen to the spec wizard.

Does a thermocouple that is designed to be bolted to a surface measure the environment very well? I want to measure the temperature of the air using a similar thermocouple
Asked by: CJames
Thank you for your inquiry C James. You can use a Bolt-On Thermocouple to take air temperature measurements.

What is meaning of Minimum Temperature Measurement - 60 in

The heading is incorrect for the column and should read "Lead wire length" and it will be corrected.

Can these be used in environments where high EMI/EMF is expected?
Asked by: rm909
It's difficult to say if these probes would be good or not in that type of environment. There is no special shielding and it is a grounded junction probe so any surface it is attached to if it had this energy induced on it would go right into the TC junction. The safest answer is no or experiment at your own discretion.

Hi, is it possible to use wtk-6-12 on an high voltage cable (70 kV) without damaging the measurement system?
Asked by: gaara
The WT series would not be suitable for mounting to a surface with any Voltage as it is a grounded junction and the readings would not be good and it could damage your instrumentation.
