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.
The Spectra Candela II-A Photometer is designed for simple one-handed convenience. Compact and easy to use light meter provides an easy, economical means of making highly accurate measurement of indoor and outdoor light levels. Measures footcandles, lux and instantly calculates Contrast Ratio, Averaging and can store up to 2 readings. Measurement results displayed on Electroluminescent backlit Custom LCD. Simply pressing one push button enables the light level to be measured and displayed on a easy to read digital LCD, which reads out directly from 0.1 to 70,000 footcandles and 1 to 100,000 lux ; a range which encompasses illumination levels from dim indoor lighting to extremely bright sunlight.
For highest accuracy, the Spectra Candela II-A Illuminance Photometer has a high sensitivity silicon cell and computer - selected glass photopic filter (to match the CIE eye response). The Calibration of Spectra Candela II-A Illuminance Photometer is traceable to National Institute Of Standard Technology (NIST). The Spectra Candela II-A Illuminance Photometer is available with a mounted swivel head and or a detachable sensor head with up to fifteen feet of cable extention. For Ultra low light level measurements, the Spectra Candela II-A Photometer is also available with an extremely sensitive sensor, which has a range from 0.01 footcandles to 7000 footcandles.
