Hi all...
Does anybody know of a source for a vacuum gauge sensor (Pirani or thermocouple) and a circuit to make an analog gauge to use them with? I don't really want to spend a thousand bucks to get a decent gauge.
Thanks in advance!

Re: Vacuum Gauges
I've gotten some good deals on eBay for thermocouple gauges, but it does require patience and paying close attention to the details so you don't get taken. As far as a circuit goes, Sam's Laser FAQ has a circuit for building your own TC meter. If my memory is correct, there is even a file you can print out for the scale.
