RS485 output. Data logging to a computer.

4-20mA output. Record data to external recorder.

BACKGROUND

FINALLY A pH CONTROLLER WITH AN ALARM INCLUDED – not just an “output” that needs electronics work to make it function, but ready out of the box.

For something as important as wastewater compliance, having an alarm to let you know when the pH is out-of-range is critical! This device monitors the pH so you know immediately if the pH is too high or too low.

pH CONTROLLER DESCRIPTION

The pH alarm points (high and low) are separate from the pH control points. (used to activate an acid and a caustic pump) When the alarm sounds, it’s easy to silence the buzzer with the front button. The buzzer will sound again in 30 minutes if the condition is not corrected. (if the default behavior is selected)

Buttons on the side of the enclosure will activate the pumps manually. This is useful for priming pumps, calibrating the pumps, testing, or emptying drums.

The yellow stack light illuminates when either pump is active. This helps to monitor the status of the system.

Rugged industrial pH probe included.

Installation consists of these steps:

Mount the enclosure.
Set desired alarm and control points.
Plug your pumps into the dangling pigtail outlets.
Calibrate.

SETTING THE ALARM POINTS

As an example, if you want the acceptable pH range set to 6.0–8.0. In this case, the acid pump would start making additions when pH rises to 8.0. You can set the hysteresis so the pump will stop when the pH is corrected to 7.5 for example.

The high pH alarm point could be set to any value, such as 9.0. (that way the buzzer doesn’t sound every time there is a routine addition) You can set any Hysteresis value you want. (so the pH alarm could stop sounding when the pH recovers 8.9 for example) video on setting alarms

BNC OPTION

For corrosive environments, a BNC connection is not recommended because it can corrode, and thus interfere with accurate measurement. Nevertheless we offer it if desired.
