ATC2 Fieldpiece Large Pipe-Clamp Thermocouple 3/8” to 2 1/4” for Air Conditioning - The ATC2, K-type, pipe clamp thermocouple is used to take temperatures of medium to large pipes or any other cylindrical surface within its 3/8” to 2 1/4” jaw range. Using a pipe clamp thermocouple greatly facilitates taking superheat or subcooling measurements. Use the ATC2 for most A/C units. The ATC2 can be used with any of our meters that measure temperature and any thermometer accepting a K-type thermocouple.

Because the jaw is designed for HVAC/R, its clamping ability lets you measure temperatures of pipes that are fixed, at any angle, to walls or other surfaces. The sensor reaches correct temperature within a minute.
