Bluelab External Lockout & Alarm Box

This Bluelab External Lockout and Alarm Box is an optional extra for your dosing system. Use to connect the Bluelab® Pro Controllerâ„¢ to external switches, for example a float switch or a greenhouse alarm system. When these switches are activated, the Bluelab® Pro Controllerâ„¢ is placed in lock out mode, so no further dosing will occur until reset.
