Mini RayTemp infrared thermometer for routine day-to-day temperature checking

• compact, lightweight & easy to use
• temperature range -50 to 330 Celsius
• laser dot alignment
• target ratio 12:1
• backlit LCD display

The Mini RayTemp infrared thermometer is a compact, lightweight and low cost infrared thermometer. Simply aim and pull the trigger to display the temperature of the item being measured.

The Mini RayTemp measures temperature over the range of -50 to 330Celsius with an assured accuracy of +/-2Celsius over the range of 0 to 330Celsius, outside of this range (-50 to 0Celsius accuracy is +/-4Celsius or +/-4% whichever is greater.

This infrared thermometer has a clear, easy to read, LCD display with low battery, and backlight indication and an auto power off facility that turns the instrument off after 10 seconds, maximising battery life. The Mini RayTemp is ideal for numerous temperature measurement applications where contact with the item to be measured is an issue.

The Mini RayTemp also incorporates laser assisted alignment as standard, to assist in pin-pointing the area of measurement. The unit incorporates a 12:1 optic ratio (target distance/diameter ratio) and a fixed emissivity of 0.95 making it suitable for a wide range of food and industrial applications.

Infra Red or Laser Thermometer Guide
An infrared thermometer's advantage against a conventional probe thermometer is speed and the fact that it is non-contact; but keep in mind an infrared thermometer only measures the surface temperature. Infrared thermometers are easy to use, simply point the instrument at the object you wish to measure and read the temperature on the LCD.

what is infrared?
Infrared energy is emitted from the surface of all objects. This energy is part of the electro magnetic spectrum. Infrared radiation can have a wavelength of a fraction of a micron up to several hundred microns. Infrared thermometers measure infrared with a wavelength of between 4 and 14 microns.

infrared thermometer limitations
As it is the surface of an object that emits infrared, an infrared thermometer will not measure its internal (core) temperature. You cannot accurately measure through any covering (glass, polythene, clingfilm etc). Any surface you are measuring must be clean and dust free. Air temperature cannot be measured by an infrared thermometer. You can read more about limitations and find our infrared thermometer FAQ here

emissivity
Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermal black surface (a black body). A black body is a material that is a perfect emitter of heat energy and has an emissivity value of 1. A material with an emissivity value of 0 would be considered a perfect thermal mirror. For example, if an object had the potential to emit 100 units of energy but only emits 90 units in the real world, then that object would have an emissivity value of 0.90. In the real world there are no perfect "black bodies" and very few perfect infrared mirrors so most objects have an emissivity between 0 and 1.
