Dual-Channel Picoammeter - ORM400

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

Extensive dynamic range measurements with exceptional linearity can be realized as this picoammeter offers short-circuit detector operation and an impressive six decades of gain.

Available with an auxiliary voltage input, the ORM400 dual-channel picoammeter can be operated from the front panel or completely automated over the USB interface. Under-load and over-load flags are included to improve optimal remote operation.
