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 0.1CF (0.01mS) below 10CF, then 0.5CF (0.05mS) from 10 CF to 40 CF and finally 1CF(0.1mS) above 40CF.
(this provides accuracy at the lower end where it is required)
Two year warranty
Graphite electrodes for minimal contamination
Easy to recalibrate by using 27.64CF standard solution
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 advantage of using a mains powered monitor is that it is possible to generate a small amount of heat inside the box which reduces the possibility of condensation forming - the main cause of failure in pH monitoring equipment. The controller will add either acid or alkali (to lower or raise the pH) .

Timed dosing for easy set-up
Resolution 0.01 pH
Range from 0 to 14pH
Replaceable BNC standard pH electrode
Two year warranty
Built-in alarm (can be turned off)
Easy to recalibrate using pH7 and pH4 buffer solutions
