This is my first post on this forum. I am a high school teacher who has won a grant for about $5K (but also have a parent who is thinking about adding an addition ~$2K) to purchase a thermal camera. I was looking at the Ti200 from Fluke but have not explored other options. Can you help? Any advice on purchasing, durability, ease of maintenance, longevity, expense of up keep, ease of use, …would be greatly appreciated.
