The compact Uni-T UT300A+ infrared thermometer enables fast non-contact surface temperature measurement in a range of -20 to 400 °C. With a response time up to 500 ms, a D:S ratio of 10:1, a backlit display, and a laser pointer, it is ideal for home use, workshops, and technical inspections.

The Uni-T UT300A+ is a practical IR thermometer for situations where the measured surface is hard to reach, hot, or unsafe to touch. It delivers stable results thanks to a fixed emissivity of 0.95 and a spectral range of 5.5–14 µm. Operation is simple and clear, so you can check the temperature in seconds.

You can use it for everyday diagnostics at home and in the workshop—checking the temperature of heating systems, piping, motors, electrical components, or machine surfaces. Practical features increase comfort and safety during measurement:

  • Data Hold to freeze the measured value
  • °C/°F unit selection
  • Laser targeting (power < 1 mW) for precise identification of the measurement spot
  • Auto power-off after 8 s to save battery
  • Low-battery indicator
  • 1 m drop resistance

The thermometer is powered by two LR03 (AAA) 1.5 V batteries, and thanks to its low weight of 146 g and compact dimensions, it is comfortable to hold and carry. It is suitable for operation within 0–50 °C at humidity <90% RH (non-condensing).
