Infrared thermometer with type K thermocouple


Key features

  • Contact and non-contact IR thermometer for measuring up close or at a distance, without a ladder
  • Measures temperature from -40°C to 550° C (-40°F to 1022°F)
  • Works with all standard mini-connector type K thermocouples
  • Provides single-point laser sighting
  • Allows easy emissivity adjustment for measuring pipes and other shiny surfaces more accurately

Other useful features:

  • Features fabric hook-and-loop fastener pipe probe for superheat, sub-cooling, and other contact and ambient measurements
  • Provides MIN, MAX, and DIF functions to help you quickly identify problems
  • Weighs only 12 ounces/340 grams) and is extremely easy to use
