Thermal Imager


Training optional, but you must feel confident in the use of the device and must have read the equipment instructions.

  • Location: the large grey standing cabinet next to the electronics workbenches.

  • Trouble Ticket - Report any issues here. Please check the information below first.

  • The thermal imager is a special sort of camera used for viewing the heat given off by an object. This could be used to identify a short circuit by looking for hotspots, or parts of a circuit that are not working properly (cold areas). Another use is for identifying parts of machinery that need lubrication since those with too much friction will appear warm.

  • To use the imager, press the red power button for 2 seconds and wait for the imager to become ready. Hold the red button for 2 seconds and click "OK" on the touch screen to turn it off.

  • The imager must be focussed for each subject so turn the rubber ring around the lens to do this. Click the trigger to take a photo but make sure you press the tick on the touchscreen to save it. Click again to return to the live view.

  • Video can be recorded by holding the trigger for at least 2 seconds and then releasing. Just click the trigger to stop recording. Images can be viewed by removing the micro SD card (look in the top rubber cover) and inserting into a computer.

  • The resolution is 320x240 and it can measure temperatures from -20 to +150 and from 0 to +650 degrees C. There is a menu option to select which of these ranges to use.

  • If using the imager for long periods of time, use the supplied mains adapter with USB-C cable to power it. Note that plugging the imager into a laptop will not allow simultaneous charging and use of the imager; the mains adapter must be used instead.


• Point at the sun or other intense energy sources.

• Force the box closed - the manual must be laid flat in the correct place before closing.

• Use it to measure temperature of visually reflective things (e.g. shiny metal) as they also reflect heat and do not emit much of their own (low "emissivity").

• Touch the lens.


• ALWAYS use the green wriststrap; the thermal imager is a valuable item that we do not want to be dropped!

• Read the manual if you wish to change any of the imager's settings.

• Charge the thermal imager on the electronics workbench if it has run out of power.

• Read up on emissivity if you require accurate temperature readings.
