Non-contact Handheld IR Thermometer Image Non-contact Handheld IR Thermometer

This non-contact infrared thermometer makes measuring surface temperature simple and safe. No need to touch hot, hazardous, or moving objects. The built-in sensor measures the amount of infrared radiation flowing from an object - the more heat, the more radiation.

Simple to use, all you have to do to check the temperature is point the sensor at an object between a couple of inches and a couple of feet away. The farther away the object is, the larger the area being measured. Simply point and press the button to get an instant temperature reading or hold button down to receive continuous readings.

  • Built-in laser pointer to improve aim
  • Large digital display with backlighting
  • Switchable °C/°F temperature units
  • Pocket size meters complete with 9V battery
  • Handheld model has Type-K thermocouple input for contact measurements
  • Field of view: 6.5 : 1
