Feature BL983320

• Adjustable Dry Contact Dosing Relay  : The BL983313 features a dosing relay that is activated when the reading is above a user programmable set point.
• Programmable Overdose Protection : For enhanced safety the mini controller can be programmed to deactivate the dosing relay if the set point is not reached within a specified time interval. The overdosing timer is programmable from 5 to 30 minutes or disabled.
