The AquaMetrix AM-2251 Input Controller turns any toroidal conductivity sensor into a super wide-range probe that can measure conductivities between 4 and 400,000 µS/mc. Choose from pH, ORP, toroidal conductivity or dissolved oxygen. Selecting, configuring, calibrating and troubleshooting the probe is so intuitive it's unlikely you will ever need the manual.
The AM-2251 provides control of external devices using its three independent relays. Each relay has adjustable high, low and in range setpoints, cycle timer, with adjustable on and off times. These features enable\ tighter control of batch processes and eliminates a chemical overshoot. The third relay can be activated by temperature as well.
Applications for the AM-2251 include:
