Milwaukee 2278-20 M12 12:1 Infrared Temp Gun, 12:1 Distance To Spot Ratio, -22 F To 1022 F Range, Tool Only

Milwaukee 2278-20 M12 12:1 Infrared Temp Gun, 12:1 Distance To Spot Ratio, -22 F To 1022 F Range, Tool Only

• Milwaukee 2278-20 is an M12 12:1 infrared temp gun designed to measure surface temperatures from -22 F to 1022 F. It uses a 12:1 distance to spot ratio and a 0.95 fixed emissivity for consistent scanning, plus a premium LCD and configurable high and low alerts. Not a replacement part.
• Features:
  • Temperature Range -22 F to 1022 F supports surface temperature checks across HVAC, electrical, and industrial applications.
  • 12:1 distance to spot ratio measures a 1 Ft spot from 12 Ft away for faster scanning at a safer distance.
  • 0.95 fixed emissivity supports consistent readings on common surfaces without emissivity adjustment.
  • User configurable high and low temperature alerts help speed up scanning by flagging out of range targets.
  • Designed for use within the Milwaukee M12 cordless system and is not a replacement part for a specific vehicle, machine, or SKU.

Q: What does 12:1 distance to spot ratio mean?
A: At 12 Ft away the tool measures approximately a 1 Ft diameter spot, so moving closer improves precision on smaller targets.

Q: Is this tool contact or non contact?
A: It is non contact and is intended to measure surface temperatures using infrared sensing.

Q: Does 2278-20 include a battery and charger?
A: No. It is sold as tool only and requires a Milwaukee M12 battery and compatible M12 charger.

Q: What surfaces is the 0.95 fixed emissivity best for?
A: A 0.95 emissivity is commonly suited to many non reflective painted, plastic, and coated surfaces, but shiny metals can read differently due to low emissivity.
