Made for multi-parameter process measurement, this loop-powered transmitter is field-configurable to measure pH, ORP, conductivity, or flow. It spans 0 to 14 pH, -999 to +999 mV ORP, and 0.055 to 500,000 µS/cm conductivity. Running on 16 to 32 V DC with a 4 to 20 mA output, it works great for water treatment, chemical dosing, and water quality monitoring.

The AM-2250TX series is built on the legacy of the SharkTX transmitter. Like its predecessor it is designed to be the most flexible, easy to use, and easy to see multi-parameter transmitter on the market.
Select the parameter you wish to measure from the easy-to-use menu. Choose Conductivity, pH, ORP or Flow. The user interface was designed under the principle that the user should not need to read the manual.
The AM-2250TX is a loop powered device. It provides one isolated, scalable 4 to 20 mA output.
The 4 to 20 mA output can be configured for PID control. Most users will only use proportional control but the integral and derivative terms are there for advanced control.
The AM-2250TX comes complete. There are no extra costs associated with buying boards for different sensors, or buying components to achieve NEMA 4X.
The AM-2250TX is packaged in a rugged NEMA 4X polycarbonate enclosure making it ideally suited for indoor and outdoor heavy-duty applications. The enclosure outline makes panel-mount cutouts simple. Pipe and DIN-rail mounting kits are available.
The AM-2250TX features a large LCD display that can be seen from a distance. The keypad allows easy entry of menu items and numeric values.
No other controller offers the same combination of flexibility and ease for calibration. The process value is visible during calibration so the user knows when it has settled down.
Calibration of pH can be with 2 or 3 points. Calibration of conductivity can take as many as 16 points so acids and bases can be measured through their conductivity. All Calibration data is stored.
