8808 Lux Meter Light Meter

Feture: Light-measuring levels ranging form 0.01lux~0.1klux/0.01fc~0.01kfc, repeatedly. High accuracy and rapid response. Data-hold function for holding measuring values. Unit and sign display for easy reading. Automatic zeroing. Meter corrected for spectral relative efficiency. Correction factor need not be manually calculated for non-standard light sources. Short rise and fall times. Peak-hold function for tracing the peak signal of light pulse with least duration 10μ S and keep it. Capable of selecting measuring mode in lux or fc scale alternatively. Auto power off 30 minutes. Maximum and minimum measurements. Relative reading & Reset function. Easy to read large backlit display Specification: Display: 3-3/4 digit LCD with high speed 41 segment bargraph.
