XYG-III All Digital Photometer


   The XYG-III All Digital Photometer is based on all digital integral photometric measurement technology. It has no analogue unit, thus it is very simple to overcome the zero drift which is impossible to be avoided in current photo-meter. The digital V(l) sensor has large dynamic range so that there is no range-changing error in it, moreover, it possesses strong anti-interference ability and high accuracy.
    The XYG-III All Digital Photometer contains RS232 computer interface, the calibration is done by software. It is suitable for monitoring and remote applications.
    The XYG-III All Digital Photometer software can calibrate the instrumentation, sample the data through RS232 interface and print out the results. It is a real-time measuring system and run under Windows98/NT.
