pH and Conductivity
Here is my fabulous new pHugly Type R pH robot. Call me if you have any questions.
Just look at those pretty little blue and white DC wires with my incredible refillable double-junction, glass bulb, epoxy-bodied, flushable electrodes. Stout, robust DC motors are housed in that aluminum extrusion and provide plenty of torque to stir your mud.
If you can't afford the robot maybe one of these cheaper manual systems will appeal to you. Or, maybe not.
This is the jig that holds ten pH or ten electrical conductivity electrodes. For the pH probes,an analog signal from the electrode is converted to a digital signal which is run through a custom algorithm in the computer software. pH is determined when the signal falls within user-defined parameters such as stability average (mV) or number of readings. The probe rack can be mounted on a gantry for unattended operation. I did this once.
See? There's ten of them. Go ahead. Count them.
