Fieldpiece’s New K-Type Thermocouples Stay Right Where The Technician Wants Them To

Brea, Calif. -- Fieldpiece Instruments has added two new thermocouples, ATA1 and ATWB1, to its extensive line of thermocouples for the HVAC/R field service technician. Designed to solve common problems encountered in the HVAC/R field service, these thermocouples have an alligator clip on the end so they stay put even when tugged on by the technician.

To do superheat, two temperatures are needed—outdoor dry bulb measuring the air stream in front of the condenser coils, and indoor wet bulb measuring the air stream at the return air register or in front of the evaporator coil. The ATA1 measures dry bulb and the ATAWB1 measures wet bulb. In both cases, Fieldpiece’s alligator clip design will hold the thermocouple in place so it can consistently measure the temperature of the air stream.

The new thermocouples work with any instrument that accepts a standard k-type plug, including the Fieldpiece SC66, SC67, SC76, ATH3, ST3, and LT17. The thermocouples come with the easy-to-store "wrap-tab" plug for lead storage. Just wrap the lead wire around the tab for convenient storage.

ATA1 Bead Thermocouple: the alligator clip holds the thermocouple firmly in place. Now the technician can be sure his thermocouple will stay in place.

ATWB1 Wet Bulb Thermocouple: technicians can measure wet bulb easily and accurately with the ATWB1. Just wet the “sock” with water, put it in an air flow, and measure wet bulb with any k-type thermometer. This also has an alligator clip to keep it in place.

“Fieldpiece designed these thermocouples after getting a lot of input from HVAC/R field service technicians. They may look simple, but they both solve real world problems better than anything else!” says Rey Harju of Fieldpiece.

The thermocouples are available immediately. Fieldpiece also offers a wide variety of K-type thermocouples for field service technicians for measuring gases, surfaces, fluids and semi-solids.
