Just MHO - I would, personally, recommend newbies find themselves a nice active gauge than worry about controllers and the like.
Here's a Pirani type for $75, but they come up cheaper than this on a semi-regular basis (in Pirani, magnetron, or full-range types):

I bought one just like this in the UK, seemingly barely used, and still in cal (!) for £10!

Re: Thermocouple gauge
Ooh, that looks like a very nice gauge especially for the price. But what is that Ethernet port looking socket on the back?
In some sort of crude sense, which no vulgarity, no humor, no overstatement can quite extinguish, the physicists have known sin; and this is a knowledge which they cannot lose.

It is a standard RJ45 connector, so you can find yourself a regular network cable and cut it to access pin-outs. Do a search here and I have posted the pin-out config for this type of gauge.
It's one reason why these things make so much sense - you can find RJ45 connectors thrown away in the back of most IT centres, whereas the cables for many older type gauges are often the most expensive thing to find.

Re: Thermocouple gauge
so could you have it display data on something like a raspberry pi?

You get a voltage output which is the pressure reading. Any way you can convert a voltage signal to a reading is fine. I just use a voltmeter, and get used to what that translates to in pressure.
