Mini controllers - Autogrow Systems

EC On-demand Doser

The EC Mini-doser is cheap enough to use as a mains powered monitor, continuously displaying the measured electrical conductivity. By adding solenoid valves or dosing pumps it becomes a low cost dosing system.

Reading can be changed to EC or CF
Timed dosing for easy set-up
Range from 0 to 99CF (0 to 9.9mS)
Resolution 0.01mS/cm
Two year warranty
Graphite electrodes for minimal contamination
Easy to recalibrate by using 27.64CF standard solution
Displays dose count
If dose count per hour exceeds user limit alarm sounds and dosing stops
Built-in alarm (can be turned off)

pH On - demand Doser

The pH Mini-doser may be used as a mains powered monitor, or, by adding solenoid valves or pumps it becomes a fully functional dosing system. The controller will add either acid or alkali (to lower or raise the pH) .

Timed dosing for easy set-up
Resolution 0.1 pH
Range from 2 to 10pH
Replaceable BNC standard pH electrode
Two year warranty
Built-in alarm (can be turned off)
Displays dose count
If dose count per hour exceeds user limit alarm sounds and dosing stops
Easy to recalibrate using pH7 and pH4 buffer solutions
