Principles and Product Knowledge of Infrared Pyrometers
An infrared thermometer consists of an optical system, photodetector, signal amplifier, signal processing unit and display output module. The optical system collects infrared radiation energy from the target within its field of view. The infrared energy is focused onto the photodetector and converted into a corresponding electrical signal, which is then calculated and converted into the temperature value of the measured target.

Benefits of Using Infrared Thermometers
ConvenienceInfrared thermometers deliver fast temperature measurement. In the time a thermocouple takes to read one leaky connection point, an infrared thermometer can measure temperatures at nearly all connection points. Besides, infrared thermometers are rugged and lightweight (all under 10 ounces), easy to keep in a holster when idle, so you can carry them during factory patrols and routine inspections.
AccuracyAnother advanced feature of infrared thermometers is high accuracy, typically within ±1 °C. This performance is especially critical for preventive maintenance, such as monitoring harsh production conditions and abnormal events that may cause equipment damage or downtime. Since most equipment and plants run 365 days a year, downtime means revenue loss. To avoid such losses, you can scan all on-site electrical equipment-circuit breakers, transformers, fuses, switches, busbars and distribution boards-to locate hotspots. With an infrared thermometer, you can quickly detect tiny changes in operating temperature and solve problems at an early stage, reducing expenses and repair scope caused by equipment failures.
SafetySafety is the most important benefit of using infrared thermometers. Unlike contact thermometers, infrared thermometers can safely read temperatures of hard-to-reach or inaccessible targets within the instrument's rated range. Non-contact temperature measurement can also be carried out in unsafe or hard-to-access areas, such as near steam valves or heating furnaces, without the risk of accidental finger burns during contact measurement. Precisely measuring supply/return air temperatures 25 feet above head level is as easy as measuring at hand level. Raytek and TIME infrared thermometers are equipped with laser targeting for easy target identification, making your work much easier.
