LXP-1数字式照度计

The most important features of LXP-1 are:

• Light-measuring levels ranging form 0,1Lx…0,1kLx (0,01FC…0,01kFC).
• High accuracy and quick time response.
• „DATA HOLD” function, for holding measured values.
• Automatic zeroing.
• Correction factor does not to be manually calculated for non-standard light sources.
• High sampling rate and quick reaction for changes of illuminance.
• „PEAK-HOLD” function for tracing the peak signal of light pulse with least duration 10μs and keep it.
• Auto power off (15 minutes) or disable AUTO power off.
• Maximum and minimum measurements.
• Relative reading.
• Easy to read large backlit display.
• USB output connect with PC.
• Four measuring ranges.
• Memory of 99 measurement result.
• Data logger for more than 16000 results.

Illuminance measurement

1FC=10,76Lx; 1kLx=1000Lx; 1kFC=1000FC

Spectral sensitivity characteristic
The applied photo diode with filters makes that spectral sensitivity characteristic is well suited to the requirements of the C.I.E. curve (INTERNATIONAL COMMISSION ON ILLUMINATION). Photo curve V (λ) as the following chart described.
