The Pritchard Tele/Micro Photometer, still the proven leader in precision photometric/colorimetric light measuring instruments after more than three decades, is known for it's superior performance, high sensitivity and maximum versatility in the lab or in the field. It features the patented Pritchard Optical System with built in attenuators, polarizers, colorimetry filters and field apertures interchangeable from 2 arc minutes to 3 degrees. Many special apertures are also available. The PR-1980A also combines five dynamic features no other light measuring system does- our patented** AutoComp and AutoRange and AutoZero features, detector overload protection circuit and internal calibration verification. This unique combination virtually eliminates human error and manual computations while maintaining a precise, error-free direct readout.
