What are the benefits of an infrared thermometer?
|
- The time-saving and labor-saving convenience of instantaneous non-contact temperature measurement. Infrared thermometers are ideal for temperature measurement of potentially hazardous applications. The speed and accuracy of infrared technology.
|
|
What is infrared? |
- Every object emits invisible infrared (IR) energy.
The amounts of energy will vary, depending on the object’s temperature. The IR thermometer detects this energy and instantly calculates its temperature.
|
|
How fast? |
- DeltaTRAK infrared thermometers measure any surface temperature in less than one second.
|
|
How far? |
- DeltaTRAK infrared thermometers will measure temperature from any distance. However, readings may be affected by Field Of View (FOV).

|
What is field of view? |
- Also called distance to spot, the size of the measurement spot changes with distance; the closer you are, the smaller the spot; the further you are, the bigger the spot. In field of view, the distance is assumed at 1 meter for most infrared thermometers.
|
|
What is thermal shock? |
- When the temperature of the thermometer itself changes suddenly — for example, going from a warm room to a walk-in freezer — it can cause temporary inaccuracies. Generally, a 20°F (11°C) change requires about 20 minutes to stabilize. This is a characteristic of all IR thermometers.
|
|
What is emissivity? |
- Emissivity is primarily determined by how reflective a surface is. A shiny, metallic surface will reflect the infrared energy of objects around it, greatly distorting the reading of that surface. To resolve this problem, affix black tape or apply a cooking oil spray to the surface before reading.
|
|
What is the red laser? |
- The laser is only a pointer to indicate where the thermometer is aiming and has nothing to do with the actual temperature measuring function of the thermometer.
|
|
How can I verify accuracy? |
- Prepare an ice bath: fill a cup with crushed ice, add water, stir and let sit for a minute. Point the laser at the surface of the water and take a temperature measurement with the thermometer. The temperature should read 32°F (0°C).
