The Spectra Candela C-305 Photometer is an accurate, pro light meter designed to yield precise measurements of ambient indoor and outdoor lighting scenarios.
This advanced hand-held meter measures foot-candles and lux. The readings are shown via a sophisticated backlit LCD system making it easier to read in low light.
Dual stage front end op-amplifier, custom sealed hybrid integrated circuitry, multiple range linear circuit controlled by microcomputer and custom back-lit liquid crystal display for highest accuracy and reliability; ultra-stable silicon detector
Accomplished by using a specially designed white molded plastic diffuser receptor; the diffuser provides cosine correction to a high degree of refinements; thus the detector correctly evaluates the light intensity regardless of direction
