ORM400 Picoammeter

  • ORM400 benchtop optical radiation meter

Offering short-circuit detector operation and an impressive six decades of gain, wide dynamic range measurements with excellent linearity can be realised.

Including an auxiliary voltage input, the ORM400 can be operated from the front panel or fully automated over the USB interface. Over-load and under-load flags are included to enhance optimal remote operation.
