The Hanna Instruments HI 9931-1 is a Wall Mounted EC Controller with Proportional Fertilizer Dosing for Hydroponics Applications. The Hanna Instruments HI 9931-1 also provides for an alarm relay which is activated when the measurements exceed the set point by a user selectable margin from 0.5 to 2.5 mS/ cm.

The alarm can be configured in either normally closed or open position and turned off during maintenance.
