Minitemp IRT659K Portable Infrared Thermometer is a portable temperature measurement instrument designed for non-contact surface temperature inspection and maintenance applications. This handheld infrared thermometer provides rapid temperature readings using infrared sensing technology and includes a K-type thermocouple input for contact temperature measurements when required.

The IRT659K is designed for technicians who require fast and accurate temperature monitoring of aircraft components, electrical systems, engines, mechanical assemblies, and other equipment. The integrated laser targeting system allows precise identification of the measurement area, while adjustable emissivity settings improve measurement accuracy across different surface materials.

The instrument provides a wide measurement capability, with infrared temperature measurement from -58°F to 1202°F (-50°C to 650°C) and extended measurement capability through the K-type thermocouple input. Its portable design, digital display, and stored measurement capability make it suitable for troubleshooting, inspection, and preventive maintenance tasks.

In aviation maintenance environments, infrared thermometers are commonly used for detecting abnormal temperature conditions, checking electrical connections, monitoring mechanical components, and supporting fault isolation procedures. Proper measurement technique, correct distance, and appropriate emissivity settings are essential for reliable results.
