HT-175 Infrared Thermal Imager

IR CameraI’ve wanted one of these hand held imagers since I heard of the FLIR – but could never justify the cost – NOW I have one of my very own.  I’m quite excited.

Here’s the link – be aware, I think the current sale offer dries up tomorrow??:

Even then the price - indeed it is Banggood (I'm sure they won't appreciate that). 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:

Heat loss through windows

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 32x32, 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.

    1. No, it’s 8,000 nm to 11,500 nm range. 1 micron (um) is 1000 nm. This is the long wavelength or ‘thermal’ infrared band.
