    Monitors and displays the pH and ORP levels using LEDs and digital readouts on the front panel. If the temperature sensor is installed, the M820 will monitor temperature and display on the front panel when in Temp mode. Additionally, it will monitor up to two chemical tanks equipped with level switches and displays status using LEDs on the front panel.
  • Page 6 An injection-molded flow cell with integrated flow switch houses the pH and ORP sensors, and partners with the M820 controller to monitor the pH and ORP levels in the water. b. The flow switch verifies that water is flowing during a feed cycle, and sends the controller instructions to deactivate the feed if water is not flowing.
