New Pipe Clamps for Fast, Hands-free and Accurate Measurements for Large Commercial and Refrigeration Systems

New Pipe Clamps from Fieldpiece Instruments

Newly introduced Fieldpiece Large Pipe Clamps are the largest pipe clamps on the market with up to 4 1/8” jaw opening.

Fieldpiece offers two new solutions for getting good readings on larger pipes with our large 4 1/8” jaw-opening clamps

Fieldpiece Instruments, HVACR tools and test instruments specialist, announces the launch of the largest jaw pipe clamps for the HVACR industry, the wired TC48 and the wireless system JL3LC. With an unprecedented 4 1/8” jaw opening the new pipe clamps are perfect for commercial and refrigeration field service professionals and also serve the residential market. The clamps, sporting a ¾” to 4 1/8” range, can be used on a wide variety of pipe sizes, especially in large commercial and refrigeration applications.

The new pipe clamps incorporate Fieldpiece-patented Rapid RailTM Sensor Technology making the response time to get an accurate temperature reading merely seconds, thereby enabling the HVACR pro to be more productive. With this proprietary technology, temperature readings are not affected by ambient air as the thermocouple is thermally isolated and the clamps will perform immediate reaction to changes in system adjustments as the technician is working. This can greatly facilitate taking a superheat and/or subcooling measurement on most commercial refrigeration appliances or commercial/residential air conditioners.

“It may not seem like a big problem, but field service professionals have a tough time getting good readings on larger pipes. Fieldpiece offers these two new solutions to that problem with our large 4 1/8” jaw-opening clamps,” said Tony Gonzalez, Fieldpiece Technical Training Manager. “Other pipe temperature tools on the market use straps or tape to hold the thermocouple on the pipe. Place our rugged pipe clamps and they will stay put making it easy to get instant, accurate readings.”

The versatile clamps fit virtually anywhere they need to and offer a secure connection even on wet or damp pipes. They are compact, and have an easy-to-open design that allows for quick single-handed placement.

When used with the Fieldpiece Job Link mobile app, the JL3LC makes it easy to record and share data. Their compatibility with Job Link means that the data can be displayed in a professional report to be emailed to the customer or home office. In addition, the JL3LC leverages a strong wireless system. Measurements are sent up to 350’ away directly to a mobile device with the Job Link App, and the JL3LC also works seamlessly with the Fieldpiece SMANs, models SM380V and SM480V. The wireless signal is able to penetrate even the thick walls of walk-in coolers and freezers.

Included with the TC48 Large Pipe Clamp Type K Thermocouple is a long 6’ kink-free cable and an Emery Cloth for Cleaning Pipes. The Job Link® System Premium Large Pipe Clamp Probe includes the probe, batteries, and an Emery Cloth for Cleaning Pipes.

The trade price for the TC48 is $99.00 and the JL3LC is $146.00. They are available at distributors now. For more information about the TC48 and JL3LC please visit, or call us at 714.634.1844.
