Try pH meter - Wikipedia, the free encyclopedia

So a simple meter is a pH (e.g. glass bulb) sensor with an amplifier to increase and offset the sensor measurement feeding into a voltmeter.

actually, read a bit further down the wiki page; there's a link to building the simplest pH meter.

If you want to know how an analog signal can be converted to digital signal you can look at: Analog-to-digital converter - Wikipedia, the free encyclopedia . There are lots of info about it right there and in the web, just ask Google
