industrial spectroradiometer iSR900
The industrial spectroradiometer iSR900 is an autonomous and high-resolution measuring system for fast and precise measurements in the UV, visible spectral range and IR.
The spectroradiometer consists of an array spectrometer without moving parts and a silicon detector with 2048 pixels. The spectral resolution is 0.44 nm.
The iSR900 is combined with an SMA-905 quartz light guide and our radiometric measuring heads for irradiance and illuminance measurement.
The iSR900 is factory calibrated to PTB. A DAkkS test in our accredited laboratory is optionally available. The iSR900 thus allows accurate spectroradiometric measurements for the evaluation of irradiance and illuminance. The low-scatter design achieves high sensitivity in the UV range. Control and data evaluation take place in the iSR900 so that only a USB or RS485 / RS232 interface is required for the evaluation.
With trigger input and output the iSR900 is ideal for automated measurements.
