Greetings and good day. Thank you for sharing this video, I am working with some old Johnson Thermostats from 1924 up to the T-4002. I was wondering if you have an air compressor hooked up to your testing machine. Would I need to have my air compressor running while I went through the building and tested each thermostat? Also, where is the easiest and best place to get a kit or the tools to properly do the job? I have not had the best of luck when trying to find a one stop shop. Thanks

I want to know where to buy the testing tools that you are using. Please help me find them. I am failing to find the tools that you are using and the tools that I need to use for my Johnson Thermostats. It's a joke on how difficult it is to try to find and buy these tools.

The branch reading: After you opened it up a bit and put the gauge on and then adjusted it, after taking the gauge off do you close the needle valve?
