ATC1 Fieldpiece Pipe-Clamp Thermocouple 3/8” to 1 3/8” for Air Conditioning - The ATC1, K-type, pipe clamp thermocouple is used to take temperatures of pipes or any other cylindrical surface within its 3/8” to 1 3/8” jaw range. Using a pipe clamp thermocouple greatly facilitates taking superheat or subcooling measurements. Use the ATC1 for most A/C units. The ATC1 can be used with any of our meters that measure temperature and any thermometer accepting a K-type thermocouple.

The sensor is virtually isolated from ambient conditions, allowing the thermocouple to read the true pipe temperature for as long as it is attached. The sensor’s large surface area and increased clamping force help the sensor reach the correct temperature within 30 seconds. 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.
