Total Grow Control pH-EC Controller

Four Parameters
Select the parameter you wish to measure from the menu. Choose from either Conductivity, pH, ORP, or flow from the menu. The user interface was designed under the principle that the user should not need to read the manual.

Analog Outputs
The 020-APHEC-1 is a loop powered device. It provides on isolated, scalable 4-20 mA output.
The 4-20 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.

Zero Cards
The 020-APHEC-1 comes complete. There are no extra costs associated with buying boards for different sensors, or buying components to achieve NEMA 4X rating.

The 020-APHEC-1 is packaged in a rugged NEMA 4X polycarbonate enclosure making it ideally suited for indoor and outdoor heavy- duty applications. A mounting kit is included for surface and panel mounting. The enclosure outline makes panel-mount cutouts simple.

One Big Display
The 020-APHEC-1 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.
