Does anyone know of a good compact pH preamplifier with an external DC supply? All of the ones I found have a lithium battery as the
source, but I can't use something with just 5yrs life. Also, I'm looking for something with a small form factor (around 3"x3").
The output can be mA, mV or V.
Thanks in advance to anyone who can help!!!
