mike,

#TIL the reason #thermal cameras were either terrible or terribly expensive was because the US restricts exporting them. 😠

@mike I also suspect one company holds all the patents =)

mike,

While searching for portable oscilloscopes, I stumbled across this bizarre combo "120x90 20hz thermal camera" with "4000 count multimeter" for ~$130 (FR01C). 😮

To contrast, a couple years ago I bought a Flir One dongle for ~$250. It had an awful 80x60 8hz camera. I sold it a month later. 🤢

I was curious how prices have improved.

A 160x120 25hz dongle can be had for ~$150 (TR160i), and a 256x192 25hz dongle is ~$200 (TR256i). Flir prices start at 5x that. START! 😅

So ya, they have improved.

@mike honestly most commercial IR cameras are so bad and so overly expensive I'd just recommend to anyone who needs to use one to just rent a nice one anytime they need it, most rental companies it's about $100/day. An IR camera with a usably high resolution generally starts at around $15-20k in my experience

[edit] actually they dropped abit, looks like you can get pretty decent in the $5-7k range now but the good cameras are still $13-$20k, still though they're $75 to rent.

mike,

@raptor85 Renting seems wasteful when you can buy a 256x192 25hz dongle for $200, shipped.

@mike depends on what you're using it for, 256x192 is decent, but if I'm doing some inspections on our equipment (or hell, just doing a yearly inspection on my home) I'd much rather have a 640x480 (technically 1280 x 960 but that's because it takes 4 pictures really fast) res with distance capture, auto blend, etc so I can just snap all the shots I need, download them, and process them later those old low res cameras took FOREVER and you had to be super close to whatever you were inspecting.

@mike It's really one of those "how much do I value my time" things, $100 to one-and-done a task is worth it to me over days to weeks with cheaper equipment.

Some #thermal camera product codes to search for. #DIY #Repair

  • TR160i (160x120), TR256i (256x192) - 25hz USB Dongle style thermal cameras.
  • TR120E (120x80), TR160E, TR256E - 25Hz standalone thermal-only cameras.
  • TR256B - 25Hz standalone thermal-fusion camera.
  • HT-A1 (220x160), HT-A2 (340x240), ET692D (320x240) - 9Hz standalone thermal-only cameras.
  • or just buy UNI-T

I can't vouch for any of these, nor would I buy anything under 200 pixels, but the point is you have choice today.
