Static: I'm using a PLC like device to drive SSRelays like here, simple and clean to switch heaters.
Kwirky: Queried American Marine about the output of their probe e-mail reply AMI "After proper calibration the probe will generate 59 mV per each unit of positive pH and the opposite will be negative mV. Example pH 7.0= 0 mV; a ph of 8.0=59mV a pH of 6.5= -30mV Good Luck...Lou Dell/AMI" Last edited by mark; 06-01-2007 at 03:17 AM. Reason: attached e-mail reply
