The ORM400 Optical Radiation Meter is ideally suited to display the measurements from the DH400 range of detectors as well as third party current generating detectors. The ORM400 has a USB 2.0 interface and is supplied with powerful calibration features and data display functions. It includes a library of standard spectral light sources to which customers may add. This accommodates greatest accuracy and flexibility when measuring light sources with a filter based instrument.
