It might be best to shop Ebay-- right now?there is? two controllers for sale, both are thermocouple and ion combination these are not tested and may not work but chances are they are repairable, all of the gauge tubes (both types) work the same but the pin locations are different so you may need to swap the wires around a bit. the thermocouple?guage tube only needs 3 wires to work even thou the socket has 8, and ion gauges you can see thru. I have 3 thermocouple controllers I bought for 5 to 10 dollars a piece hopeing one would work--they all do,, but all needed re-wiring because of there age,
---I will use the system for cathode ray tube recovery, and the diffusion pump I need is about 4 inches in diameter (200 liters/second?). Respect to chamber, the bigger CRT is 36" which could be considered as a chamber of 6 cubic feet.
Respect to gauge, I need to measure up to 10-7 mm Hg. I think Ion type would be addecuate. I will appreciate your answer.
