Here you will find infrared thermometers for measuring temperature without contact. Our infrared thermometers makes possible a temperature measurement without contact by way of determining an objects emitted infrared radiation. All infrared thermometers (non-contact) contain a targeting light to ensure the correct surface area is being measured. Infrared thermometers can only measure the temperature of exposed surfaces and not through glass. Some models possess a preset emissivity value, and others allow the user to choose the emissivity value depending on the surface material being measured, whether it's paper, wood, metallic surfaces, etc. If the user measures shiney metallic surfaces, such as cylinders, the device can only be used to determine tendencies in temperature as it's no possible to measure absolute temperature with a non-contact thermometer of polished or shiney surfaces.
