These advanced controllers and recorders use Eutech pH 2000 controllers and a 30-day recorder for documentation. Choose from either free standing benchtop models or wall-mount models. Multiple control options are available for precise process control. Controller’s feature two programmable relay outputs for set points, delay, and hysteresis or control functions. A separate programmable relay is included for alarm functions. Each controller features two galvanically isolated and scaleable 4-20 mA outputs for control or recording purposes. Switchable latching/pulse wash relay is programmable for both interval and duration.

Programming of the unit is performed through the user-friendly dual-line backlit LCD. Programming is secured by two level password protection and parameters are kept in non-volatile memory so there is no need to re-program when unplugged or moved. Full specifications listed under SKU 56715-00.

Benchtop Models include a single-input Eutech pH 2000 controller and your choice of models with or without a built-in recorder.

Wall-Mount Models feature a waterproof NEMA 12 enclosure that houses all measurement, control, and recording functions behind a windowed door for easy visual checks. Single input model controls and records from a single controller. Dual input model allows either feed-forward or feed-backward control and records the value from one controller.
