The Mini Doser continuously measures the pH in the mixing tank and adds either pH Down (acid) or pH Up (alkali) as required to maintain the pH set point.
The controller counts the number of doses and in the event of the dose count per hour exceeding a set value, an alarm can be sounded. In addition alarms can be set to sound should the pH wander outside user set limits. If the dose count per hour exceeds a user setting – the controller will stop dosing.
This is a great little machine that is aimed at the budget conscious and those who do not need a computer interface. It is ideal for hobby gardeners and schools; even large commercial growers use them – particularly for water pre-treatment (pH) or if they have a trial area with a number of reservoir tanks.
The Autogrow Mini Doser pH Complete Kit comes with a sensor and one or two economy solenoid valves pre-wired on a small mounting panel. Choose one solenoid only if you know your background water only needs to be dosed one way – either up or down.
