Digital lys måler som leser av i både LUX og Fc.
Standards:
C.I.E. (International Commission on Illumination)
Application areas:
Industrial applications, factories, offices, hotels,
schools, hospitals, shops
Features:
Light can be quantified in many ways, i.e., Lux,
Lumens, Foot-candles, candle power, candelas,
and so on. The two most common scales are Lux,
used in Europe, and Foot-candles used in the U.S.
In Short:
High accuracy and rapid response.
Peak-hold function for tracing peak signals of light pulse with least duration 10µs and keep it.
Capable of selecting measuring mode in lux or fc scale alternatively
Measurement rate: 1.5 times per second
Maximum and minimum measurements
Relative reading and reset function
Easy to read large backlit display
Standard delivery:
Carrying case with ready to use digital meter, instruction manual and battery
