Hi,

Why not get the data sheeet on a MAX406? It has all that information. You will be able to set gain in the same manner as any op amp. If you want something better, check out a OPA134. you get an order of magnitude better input impedance.

What kind of probe are you using? The standard calomel electrode puts put 59.2 mv/pH unit. Your full-scale outout should be +/-414.4 mv.
