The Model PMLX Precision Photometer is designed to measure both illuminance (the amount of light falling on a surface) in lux (lumens per m2) and luminance (the amount of light emitted from a surface) in ‘nit’ (candela per m2).
The Precision Photometer quickly verifies that collimator light sources are in accordance with regulations. It also measures the brightness and uniformity of an X-ray viewbox for appropriate brightness and uniformity. When used for Mammography Quality Control, the photometer will provide measurement of viewer luminance and room illuminance required by MQSA guidelines.
The optional rigid fiber optic probe can be used to make measurements of SMPTE* patterns produced by digital display units, in order to determine appropriate density and contrast settings for image display monitors.
The battery operated photometer has a bright LED display and only two operating controls: “Measure” for taking readings and “Range” to adjust the meter display to the light being measured.
