Not realy testing equipment but hot air rework station. Works great to remove potting! Put the temp between 100 and 150 degrees so the solder does not melt. You can pick off the potting pretty easy with a razor blade or pin.
It is a Chinese product based on a few chips sold with different brands and very very cheap.

I have never worked with hot air before. I tried to desolder a big transistor but that seems to damage the board. Desoldering smd components works fine at lower temperatures but still the components get a little brown. For now I am using desolder wick again but some smd inductirs have the solder side underneat than I need the hot air.
So my question is what temperature do you guys use? I found 150 to work well with potting because that temperature does not meld the solder. At 350 I got the burn marks.
I go to about 270-280 with no issue, you have to keep moving the wand so not to burn one area. I also have a chip suction device that i connect to the chip first and slightly keep upward pressure on it as I heat up the pins around it. then it just pops off.

jbmeyer13: Wolfy's Marquee isn't working? Did you spill a pint on it and short the MB?

wolfman: Always the same sarkasm Kurt that's why I never checked in until now. I knew you wouldn't give me a cheerful answer so let you hang for a while. Removed the last part you probably are a decent guy Eye to Eye.
