Ultralife 'Accu-Max I' Controllers

    The Ultralife 'Accu-Max' single channel monitor/controllers are designed for continuous operation without interruption. They feature a large .5 inch LED display, piggy-back relay module, recessed adjustment screws and an adjustable 'deadband'. We feel the last feature is the best feature of all. The adjustable 'deadband' (control span) allows for user adjustment to the desired control range. The 'Accu-Max I' controllers are supplied with highly accurate custom pH or ORP epoxy body electrodes with 10 ft cable and BNC connector. We also sell Ph Meters (Model M301), the difference being they are designed for monitoring only, the do not have the relay control operation. The meters also come supplied with highly accurate custom pH epoxy body electrodes with 10 ft cable and BNC connector.
