Product Details

The 4485TR combines the convenience of noncontact infrared temperature measurement with the flexibility of contact thermocouple monitoring. Users can instantly measure surface temperatures by aiming and pulling the trigger, or connect the included Type K thermocouple probe for direct-contact applications requiring extended temperature ranges.

Adjustable emissivity settings improve accuracy when measuring different surface types, including metals, plastics, painted surfaces, ceramics, food products, and industrial equipment. This flexibility helps produce more reliable readings than fixed-emissivity infrared thermometers.

The circle-dot laser system visually identifies the approximate measurement area, helping users accurately target surfaces and improve measurement confidence. The 12:1 optical ratio enables safe measurements from a distance while maintaining accuracy.

Advanced functions include minimum and maximum tracking, differential temperature calculations, time-weighted averaging, and programmable temperature alarms. The dual-display design allows users to view current temperature alongside alarm settings, emissivity values, probe temperatures, or calculated measurements.

The Type K thermocouple input expands measurement capability to temperatures as high as 1400°C (2552°F), making the instrument suitable for furnaces, ovens, process equipment, manufacturing operations, laboratory testing, and maintenance inspections.

Each thermometer includes an individually numbered Traceable® Certificate documenting traceability to recognized national measurement standards. Guaranteed to have at least one year of calibration remaining on the certificate.
