The Konica Minolta CRI Illuminance Meter CL-70F offers a user-friendly solution for measuring and evaluating various illumination sources, including LEDs, OLEDs, and fluorescent lamps. This entry-level lux meter excels at measuring illuminance, color temperature, color rendering index (CRI), chromaticity, tristimulus values, spectral irradiance, flash, and more, making it an essential tool for professionals across various industries.

CRI Illuminance Meter CL-70F

The Konica Minolta CRI illuminance Meter CL-70F, compliant with JIS A-Class and DIN Class C standards, is an entry-level lux meter for accurate and comprehensive light measurement. This versatile lux meter allows users to measure illuminance, CRI (Color Rendering Index), tristimulus values, chromaticity, correlated color temperature, spectral irradiance, peak wavelength, dominant wavelength, excitation purity, difference values, and more.

Ideal for evaluating various indoor or outdoor lighting like LED, Organic LED (OLED), and fluorescent lights, the CRI illuminance Meter CL-70F is also a valuable tool in specialized lighting applications in broadcasting stations, studios, stages, and events. It can also handle environmental light measurements, including sunlight and light source checks at construction sites.

The CRI illuminance Meter CL-70F also allows for the measurement of flash light, either by synchronizing with a cable connection or in cordless mode, ranging from 20 to 20,500 lx•s; 2,500 to 100,000 K.

The CRI illuminance Meter CL-70F’s key features are designed with user comfort in mind. Its rotatable receptor head ensures easy reading from the meter display, regardless of your lighting measurement scene. It also comes with a large color screen display with touch panel functionality, making operation a breeze. Users can even customize the displayed content to suit their needs.
