We are happy for customers to test out our products in person. To do this, they must make an appointment to visit our exclusive UK & ROI distributor, Thomas Jacks, base in Stratford-upon-Avoid. However, please note that if you arrive at the Thomas Jacks offices without an appointment, you may not be able to access the building and you could be turned away.

Alternatively, you can check with your nearest retailer to see if they have demo stock available. To find your nearest retailer, visit our dealer locator page.

No, glass does not let infrared radiation within 8-13ɥm pass through it, therefore no thermal imaging device is capable of seeing through glass.

A thermal imaging device is only able to detect a body’s surface radiation. It is possible to detect a crack in a wall, or to locate defective thermal insulation, but seeing through walls is not possible.

Pointing a thermal imaging device at a powerful source of energy (for example: a unit emitting laser radiation, or the sun) with the lens caps open can have a negative impact on the accuracy of the device.

Although many modern thermal imaging devices are able to operate effectively in extreme conditions and temperatures, we do not recommend using a device in temperatures exceeding +50°С, as temperatures this high may damage the unit.

Calibrating a thermal imaging device allows it to level the background temperature of the microbolometer, eliminating image flaws such as vertical stripes and ghost images (wherein the faint image of an object will remain visible on screen even when it is not being observed). Intervals between the need to calibrate depend on operating time — the longer a thermal imaging device operates in continuous mode, the less frequently a calibration is needed.

A thermal imaging device is completely safe. It does not emit anything; it only receives and analyses incoming infrared emissions from objects.

A thermal imaging device’s refresh frame rate, measured in Hertz (Hz), tells the user how many times a second the thermal image is refreshed on the unit’s display. A higher refresh rate makes observation of fast moving objects more comfortable. The lowest frame rate is 9Hz. It is important to know that thermal imaging devices with a refresh rate of 30Hz and 50Hz may have export limitations depending on the laws in your region.

Observed objects’ thermal signatures will increase faster at positive temperatures, allowing for higher temperature contrast and an overall greater image quality when compared to that of a thermal imaging device used in colder temperatures. In lower temperatures these objects usually cool down to roughly equal temperatures, leading to lower temperature contrast and thus resulting in the degradation of image quality.
