Ultra Low Light and Low Light Lux Meter

The CS-ULM200 Ultra Low Light Lux Meter and CS-LLM100 Low Light Lux Meter are professional photometric instruments designed for illuminance measurement across a wide range of lighting conditions. They are suitable for optical laboratories, LED lighting evaluation, display testing, scientific research, industrial inspection, and environmental light assessment.

Both models incorporate high-sensitivity photometric detectors with V(λ) correction, providing spectral responses closely matched to the standard human eye sensitivity curve. This helps reduce spectral mismatch errors and improve measurement consistency.

Combined with low-noise signal amplification and 32-bit high-precision ADC technology, the instruments provide reliable illuminance measurements for both ultra-low-light and low-light applications.
