Fluke FLK-TIS60+ 30HZ Infrared Thermometer

Infrared thermometer with adjustable emissivity

The Fluke FLK-TIS60+ is a non-contact infrared thermometer built for HVAC technicians and maintenance professionals who need to verify surface temperatures quickly. It offers a measurement range from -4 °F to 752 °F and features a single-dot laser sighting for targeting. Four presets and an adjustable emissivity range from 0.10 to 1.00 allow the user to match the instrument to different surface materials. The transparent housing distinguishes this model visually.

Distance-to-spot ratio defines practical range

A 532:1 distance-to-spot ratio means the measurement spot grows one unit wide for every 532 units of distance, so accurate readings on small components require the operator to stand relatively close. The field of view spans 34.1 degrees horizontally by 25.6 degrees horizontally, framing the area captured by the sensor. Alerts are delivered through a digital display and a visible light indicator rather than audible alarms. There is no secondary measuring method such as a contact probe included.

Emissivity adjustment decides material accuracy

The adjustable emissivity setting from 0.10 to 1.00 is the single specification that determines whether this thermometer will read correctly on a given surface. Low-emissivity metals such as polished ducts or copper pipe reflect ambient radiation and will produce significant errors if the emissivity is left at the default high setting. Users who cannot identify or set the correct emissivity value for their target material should select a different instrument.
