Illuminance Meter
Konica Minolta CL-70F
The CL-70F Illuminance Meter is a versatile, entry-level solution for comprehensive light source analysis. This portable, handheld device measures a wide range of lighting parameters including Color Rendering Index (CRI), spectral irradiance, and correlated color temperature across a wavelength range of 380-780 nm. Designed for in-field use, it features a rotating sensor head and touch screen for easy operation in various lighting conditions. The CL-70F is ideal for evaluating both traditional and modern light sources, including LEDs and EL lighting, in applications ranging from interior design to psychological research environments. Its ability to measure photographic flash with a sync cable adds to its utility. Conforming to DIN 5032 Part 7 Class C standards, this cost-effective meter comes with CL-SU1w utility software for enhanced data capture and analysis, making it an invaluable tool for lighting professionals and researchers alike.
