Even then the price – indeed it is Banggood (I’m sure they won’t appreciate that).
HT-175 Infrared Thermal Imaging Camera Thermal Imager — https://goo.gl/3MCC1M
Likely there are a billion uses for these hand-help gadgets (this one comes with a spare battery pack) but my first priority as we are refurbishing the house, is to check where the highest heat losses are.
First of all, then, the box photo:
Of course, I’m just playing at this point but the camera is able to manage accuracy within 2C and above you are seeing heat loss through my windows and an open door (below).
Good gadget… feels solid… I like it. When turning on and off, hold the button for a couple of seconds.
Not a lot of heat coming of those LED wall lights, as you’d expect – CONSIDERABLY less than some of my few remaining fluorescent lights.
The camera output can be in Technicolor or grey-scale as you prefer, resolution is 32×32, range –20-300c and accuracy 2c. It runs on 3 AAA alkaline batteries (not supplied). Wavelength coverage is 8-11.5um (that last one meant nothing to me).
Not to be confused with an expensive FLUKE camera, this device has fixed focus, an image capture frequency of 6Hz and a drop resistance of 2m. For the price, pretty good.
