Never before has thermal imaging been so affordable

Bridging the gap between IR thermometers and Thermal Imaging Cameras, the FLIR T165 uses it's patented Lepton® thermal detector and displays a thermal image of 80 x 60 pixels while providing a highly accurate temperature measurement using the dual laser pointers.

As with standard IR thermometers, the TG165 provides a single temperature measurement, however users will greatly benefit from the heat patterns that the thermal image will display. This greatly increases the speed and efficiency of any job where obtaining temperature measurements is involved while giving you confidence that nothing will be overlooked.

The FLIR T165 Imaging IR Thermometer is simple to use, offering intuitive menu icons and a simple "switch on and go" operation, with no prior training is required. Using the FLIR TG165 dual laser pointer with a spot ratio of 24 to 1 (24:1), you can obtain accurate temperature measurements from a safe distance and images can be stored on a micro SD card as a Bitmap file by simply squeezing the trigger. A 8Gb Micro SD card is supplied with the TG165 allowing storage of up to 7500 images).

The TG165 has an impressive temperature range from -25°C to 380°C and the thermal detector will pick up and display thermal patterns down to 0.15°C (150mk). Within your menu options you can adjust the emissivity value between four preset values according to your surface material properties or you can set the value manually yourself to obtain the truest possible temperature reading.

Weighing just over 300g the FLIR TG165 is light and compact, manufactured in a rugged design and drop tested from 2 meters. The TG165 can also be mounted to a tripod if required.

The FLIR TG165 is an affordable option for obtaining fast and accurate temperature measurements alongside a thermal image. Suitable for a range of applications including fault finding and obtaining measurements on electrical installations and components, pipes, valves, radiators, motors and bearings and even building insulation problems.
