Fieldpiece ATB1

The ATB1, K-type bead thermocouple is used to take temperatures of air, surfaces, or liquids up to 400°F. Using the included Velcro strap allows for easy pipe temperature measurements, though not as accurately as the ATC1 Pipe Clamp Thermocouple. Use the ATB1 for outdoor dry bulb temperatures when finding target superheat. The ATB1 can be used with any of our meters that measure temperature and any thermometer accepting a K-type thermocouple.


  • ATC1 jaw range: 3/8" to 1 3/8" pipe diameter (outside diameter)
  • Accuracy: +/- 4F (2C) ; +/-1F (0. 5C) after field calibration, 32 to 176F (0 to 80C)
  • Thermocouple conductors: K-type nickel chromium/nickel aluminum.
  • Plug: K-type thermocouple male mini plug.
  • Temperature range: -50 to 257F (-46 to 125C)
  • The wrap-tab allows the thermocouple wire to conveniently store on the plug
