An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation or cavity radiation. On its most basic design an infrared thermometer consists of a lens to focus the infrared (IR) energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation.it is also called laser thermometer. Infrared light works like visible light — it can be focused, reflected or absorbed. Hand held IR thermometers typically use a lens to focus light from one object onto a detector, called a thermopile. medical equipment online.
Applications of Infrared Thermometers
The major applications of infrared thermometers are given below:
- Heating and air conditioning — Detection of insulation breakdown, heat loss and gain and furnace and duct leakage
- Industrial/Electrical — Determining motor/engine cooling systems performance, boiler operations, steam systems and detection of hot spots in electrical systems and panels
- Food safety — Checking equipment performance, sanitation and process temperature conditions, and scanning refrigerated display cases, trucks, storage areas and cooling systems
- Agriculture — Monitoring plant temperatures for stress and animal bedding to detect spoiling. surgicals in kottayam
Types of Infrared Thermometers
Spot infrared thermometers
Spot infrared thermometers that measure the temperature of a small area on a surface. It consists of non-contact surface temperature readings so you can quickly and easily take measurements in places that are out of reach.
Infrared scanning system
These devices scan a wider portion as the spot thermometer points at a rotating mirror. They are widely used in manufacturing processes involving conveyors or web processes, such as continuous piles of material along a conveyor belt or large sheets of metal or glass exiting an oven. It is the part of the electromagnetic spectrum that we perceive as heat.
Infrared thermal imaging cameras
A thermal imaging camera is a type of thermographic camera used in firefighting. These cameras are essentially infrared radiation thermometers used for measuring temperature at many points over a relatively large area to create a two-dimensional image called a thermogram. This technology is more software- and hardware-intensive compared to other types of infrared thermometers.Hospital Equipment online
Infrared (IR) thermometers are not harmful to kids as long as you don’t let your them play with it, they are not toys. IR thermometers do no emit radiation, only measuring it like a digital camera. Like all portable electronic equipment, they use batteries en these can be harmful when swallowed.
