Spectra Professional meters are advanced and true digital exposure meters. Compact and easy to use, they are the most comprehensive, technologically advanced and reliable exposure meters for cinematographers, lighting designers, videographers and professional still photographers. The Spectra Professional Line of meters have been the industry standard and the choice of professionals for the past 50 years. Spectra has received several International Awards including Six Technical Academy Awards from the Academy Of Motion Pictures Arts and Sciences, Primetime Engineering Emmy Award from the Academy of Television Arts and Sciences, and an Outstanding Achievement in Engineering Development from the American Society Of Lighting Designers for the design, development and manufacture of technically superior products important to these industries.
This compact and user-friendly light meter provides an easy, economical means of making highly accurate measurement of indoor and outdoor light levels. It measures footcandles, lux and instantly calculates Contrast Ratio, Averaging and can store up to 2 readings. Measurement results are displayed on an Electroluminescent backlit Custom LCD. It has a digital f/stop range from f/0.35 to f/128 in i/10th stop increments and an Analog Bargraph range from f/0.7 to f/45 in 1/3rd stop increments.
The optional Spectra One Degree Photospot is a unique accessory that converts your Spectra Professional meter into a high-sensitivity one degree Spotmeter for narrow-angle reflected-light measurements. Readings are displayed in reflected f/stop or in footlamberts in luminance mode.
NOTE: This meter is available in four colors: Black, Blue, Green and Yellow.
NOTE: This kit includes the accessory One Degree Photo Spot

|Exposure Calibration||IMPORTANT!:You should not attempt to recalibrate the meter yourself. Recalibration of the meter requires both an equipped calibration laboratory and an intimate knowledge of the internal workings of the instrument. A recalibration and maintenance service is available from Spectra Cine, Inc. or an authorized service center for a nominal charge. There are no user-serviceable components inside the meter. Opening the meter will void your warranty. The meter is equipped with an indicator which will signal if the cover has been removed by other than factory authorized personnel.|
