  • Laser sighting for precise targeting
  • Adjustable emissivity from 0.1 to 1.0
  • Fast 500ms response time
  • Auto-off function after 7 seconds
  • Lightweight and ergonomic design
  • Runs on 2 AAA batteries (included)


In testing, the Kizen LP300 Infrared Thermometer Gun proved to be a highly accurate and consistent thermometer for measuring the temperature of various surfaces. The laser sight made it easy to pinpoint specific spots to take readings. The thermometer gun yielded temperature measurements within 1-2°F when compared to IR thermometers from Fluke and Etekcity.

The adjustable emissivity settings allow the Kizen LP300 Infrared Thermometer Gun to compensate for different material surfaces like metals or painted surfaces. While not a clinical-grade instrument, it provided more than enough accuracy for automotive, cooking, and HVAC applications. The large LCD display makes it very easy to read temperatures in different lighting conditions.

Technical Parameter Analysis


Resolution refers to the clarity of the images produced by a thermal imager, usually expressed in terms of pixels. A higher resolution results in clearer images with more detailed representation. When selecting a thermal imager, it is important to consider whether its resolution meets the actual requirements, especially in situations where fine measurements are needed.


Sensitivity refers to the ability of a thermal imager to detect temperature differences. It is typically expressed as the minimum temperature change detectable, measured in degrees Celsius or Fahrenheit. A higher sensitivity enables the thermal imager to detect smaller temperature variations, thus performing better in identifying tiny heat sources or temperature differences.

Temperature Range

Temperature range refers to the range of temperatures that a thermal imager can measure. Different thermal imagers have different temperature ranges, typically spanning from negative temperatures to higher temperatures. When selecting a thermal imager, it is necessary to determine the required temperature range based on the actual application scenarios to ensure it meets the needs.

Ease of Use

The Kizen LP300 infrared thermometer is designed to be simple and intuitive to operate. To take a measurement, you simply point the thermometer at the target surface, press and hold the trigger button, then release to view the temperature reading.

The laser pointer aids in aiming and guarantees you are measuring the exact area you want. The thermometer turns on instantly and gives readings in less than a second, allowing you to quickly scan for hot or cold spots.

With the auto-off function, you don’t have to worry about manually turning it off to conserve battery life. Overall, it provides a very user-friendly experience for both novices and professionals.
