AquaMetrix 2250 Multiparameter Analytical Controller and 2250-TX Transmitter

AquaMetrix' 2250 series is the latest in a long line of flexible multi-parameter analytical controllers and transmitters from AquaMetrix and Water Analytics.

Select your measurement parameter (pH, ORP, conductivity, or flow) from the easy-to-use LCD menu on the inside front cover. The 2250 provides control of external devices using three independent control relays. The 2250TX is designed for applications where you only need a single 4-20 mA output and no relays.

The 2250 comes in a NEMA 4X polycarbonate enclosure, so it can be used in indoor or outdoor heavy-duty applications, like industrial process control, municipal water and wastewater treatment, neutralization, fume scrubbers, HVAC, cooling towers, or boilers.
