It seems to work well. I just am not fluent in my Chinese. I can't read anything.

I work in HVAC and this camera makes my job almost too easy. No more needing to physically hook up probes, reach things on ladders, or wait for thermocouples to acclimate. Its super handy to have a picture of temperatures and problems to be able to show customers. After having it for two weeks, I've already used it to check steam traps, find a pipe behind a wall, and verify a fan coil has water flow. The resolution is very high and this works with my iPhone 17 flawlessly. The only drawback is that it defaults to Celsius every time. It can be changed to Fahrenheit in the camera roll but that is not super efficient. On the flip side, I am starting to learn Celsius.
