ORM400 - Picoammeter

The ORM400 dual-channel picoammeter from Bentham is used as a data acquisition interface in DC systems using current generating detectors.

Wide dynamic range measurements with excellent linearity can be attained as this picoammeter offers short-circuit detector operation and a remarkable six decades of gain.

The ORM400 dual-channel picoammeter, available with an auxiliary voltage input, can be operated from the front panel or totally automated over the USB interface. Under-load and over-load flags are added to enhance ideal remote operation.
