The new Mini Doser continuously measures the pH in the mixing tank and adds either pH lower (acid) or pH raise (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.

The solenoid valves are resistant to acids and alkalis at a concentration of 2% which is adequate for most small systems. Special chemically resistant valves or peristaltic pumps are also available for larger systems.

The new Mini Doser pH complete kit comes with a sensor and one or two economy solenoids 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.
