Product Description: Visible light emitted by fluorescent lamp, metal halide lamp, high voltage sodium lamp or incandescent lamp can be measured. One lux is the light received on the surface of a candle with a vertical intensity of 1 meters and an area of 1 square meters. One FC is the light received on the surface of a 1 inch square foot at a distance of 1 feet from a candle with a light intensity. Product Function: Data hold Auto/Manual range MAX/MIN function Relative function Units of measure: Lux/Fc Selecting light source Self-defined light source coefficient Product Specification Range LUX/FC：1000、10000、100000 Accuracy: ±(3% 5Lux) (at 2854°K incandescent lamps) ±(6% 5Lux) others Cosine angle deviation characteristics 30° ±2%; 60° ±6%; 80° ±25% Calibration: Calibrated to a standard incandescent lamp at color temperature 2854ºK Resolution: 1LUX/1FC Sensor: Silicon photo-diode and spectral response filter Operating conditions: Temperature:0～40°C Humidity:<80%RH Altitude :<2000m Storage conditions: Temperature:-10～50°C Humidity:< 80%RH Sampling rate: Approx. 2 times per second Spectral range: 320～730nm Auto power off: 10 minutes Power: 3 x 1.5VAAA(LR03) batteries (Batteries not included) Package Include 1* Digital Lux Meter 1* User Manual Like this:Like Loading...
