With the Fieldpiece TC24 Pipe Clamp Thermocouple 3/8” to 1-3/8” for Air Conditioning, you can get the right temperature immediately. If you’re working with residential and light commercial cooling systems, use the TC24 Pipe-Clamp Thermocouple to get pipe temperatures fast, even if it’s hot or windy. The TC24 fieldpiece temperature clamps quickly measure temperatures from fixed pipes to walls or other surfaces at any angle. The sensor is specifically designed for pipe temperature readings. Readings are highly accurate and fast. It’s designed to work on pipes or any other cylindrical surface between 3/8″ and one 3/8″, and it connects to any measuring device with a Type-K thermocouple jack.

The Fieldpiece TC24, 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 TC24 for most A/C units. The TC24 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 actual 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.

Some features of this Pipe-Clamp Thermocouple include the typical stabilization time of fewer than 30 seconds. It also features a Type-K thermocouple male mini plug. The Type-K thermocouple conductors are nickel-chromium/nickel aluminum.
