Quick Start
- Plug your TC48 into a compatible Type K thermocouple mini jack.
- Perform a field calibration for best accuracy. See “Field Calibration” later in this document.
- Clamp onto an electrically-conductive pipe.
- Take the measurement once the reading stabilizes.

WARNING
Do not remove the clamp from a pipe by pulling on the cord. Doing so might
damage the sensor.
The entire clamp may become hot when testing hot pipes or cylinders. Use
caution when handling.
Description
Use your new TC48 Large Pipe Clamp Type K Thermocouple to take temperatures of pipes or any electrically conductive cylindrical surface measuring between 3/4’’ to 4 1/8’’ in diameter.
The reach of this clamp’s jaws covers most sizes seen in residential and commercial systems. The clamp’s design enables a quick setup onto the line set with a single-handed operation.
The patented Rapid Rail™ sensor is specifically designed for pipe readings. Readings are extremely fast and accurate. Easily measure the temperature of pipes that are affixed to walls or other surfaces, regardless of angle. Connect your TC48 to a thermometer with a compatible Type K thermocouple mini jack.
Operation
Field Calibration
Due to variances in the thermocouple wire and other parts of the system, a field calibration to a known temperature (ice water) should be conducted before use. Depending on the meter, field calibration typically gives an overall accuracy of ±1°F (±0.5°C). Refer to your meter’s operating manual for calibration instructions.
Also, note that calibration is recorded on the meter’s side. Calibrate your meter to the clamp every time you connect the clamp to the thermocouple jack for best results.
Rapid Rail™ Sensor Advantages
Traditional pipe clamps sit on top of the pipe surface. Some sensors touch the pipe, some have a material between the pipe and the sensor. They can be affected by wind, heat, corrosion, insulation, paint, dirt, etc.
The Rapid Rail™ sensor uses the pipe itself to complete the thermocouple circuit. The pipe is part of the sensor! If you get a measurement, you know it’s correct.
Because the pipe is the thermocouple junction, all you need is enough contact for conductivity. This means the clamp can sit on an angle or on a bend without loss in performance.
When used with the SMAN® Refrigerant Manifold, there is a beeper and to
indicate whether or not the circuit is closed and a temperature is being
measured:
Double beep = Open Circuit (No temp)
Single beep = Closed Circuit (Display temp)
If you don’t get a pipe temperature measurement, there’s something on the pipe that’s blocking the electrical circuit (and accuracy). Sometimes you can slightly rotate the clamp back and forth around the pipe to cut through contaminants. Sometimes you need to sand the pipe a bit.
Maintenance
CLEANING: Clean the exterior with a damp cloth. Do not use detergents or solvents.
