JL3LC  Large clamp style probe to get your

pipe temperatures fast

With the ability to measure pipes up to 4 1/8”, our new wired [ TC48] and wireless pipe clamps are large and in charge – a perfect match for any commercial or refrigeration HVAC-R Technician in search of lightning-fast precision readings without the inconvenience of straps, tape or zip ties.

Our patented Rapid Rail™ Sensor Technology uses electrically conductive pipe to complete the circuit so readings stabilize immediately, unlike the other guys that can take several minutes.

Plus, measurements are not affected by ambient air, wind, or moisture on the pipe surface – culprits known to throw readings off by as much as 3-4 degrees.

  • As the fastest pipe clamp in the industry, go to the Fieldpiece Job Link® System mobile app enabled JL3LC —enabling 100 mtrs + wireless communication of full system details with building managers, documenting system performance, and more. It also communicates wirelessly with the SMAN® Refrigerant Manifolds, models SM380V and SM480V. 

No matter your preference – both the TC48 and JL3LC are sturdy, rugged, reliable and extremely accurate no matter the environment.



Features and Specs:

  • Pipe Contact Surface Compatibility: Electrically conductive
  • Pipe Size Compatibility: 3/4" to 4 1/8" (19.05mm to 104.78mm) OD
  • Rapid Rail™ Sensor Technology thermocouple (nickel chromium / nickel aluminum)
  • Measurement Range: -46°C to 125°C
  • Stabilizes in 3 seconds
  • Waterproof, rugged, and built to withstand the rigors of field use




Logging is activated.. 

Log multiple parameters at one time to get the right analysis of your system. To obtain a Superheat or Sub-Cool Log, add the refrigerant in the field provided after downloading your data from the JL3PR pressure Probe..... the Saturation Temperatures will show for your readings. Meld the table cells from your JL3LC Pipe Clamp Probe Log... either Suction or Liquid line & your superheat or subcooling values will be presented.

Use the JL3LC to test your delta T. across the filter drier.... Temperature differences over 1.0 degrees C need to be monitored for loss of system efficiency.
