Re: pH Controller and probe (cheap)

> Does anyone know of a pH controller that sells for less than $199.99? What
about pH probes that go for less than $50?
    The Broadly-James "Silver" probe is available for less than $40 from Pet
Warehouse, http://www.petwhse.com/.  I think it's the one that George Booth
recommended at his Aquatic Concepts site,
http://www.frii.com/~booth/AquaticConcepts/.  It was worked OK for me.
    If you have the time and want to try your hand at building your own
simple pH measurement and control circuit, you can try my site:
