Introduction
- The digital luminescence meter is a precision instrument used to measure luminescence (Lux, Foot-candle) in the field.
- It does meet and comply with CIE Photopic spectral response.
- Fully cosine corrected for the angular incidence of light.
- Compact, tough and easy to handle owing to its construction.
- Stable light sensitive component, Long-life silicon photo-diode and spectral response filter
Salient Features
- Data Hold facility to freeze the displayed data
- Auto ranging
- Annunciator display and automatic zero facility
- With USB Interface for PC connectivity
- The 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
- Measures in both Lux and FC scales
- Meter corrected for spectral relative efficiency
- Auto Power off facility
- Max and Min recording Facility
- Relative measuring Facility
- Displays Both in Lux and Foot-candle
