The measurement screen specializes in basic functions and displays the values essential for light measurements, such as illuminance, color temperature, Δuv, color rendering properties (CRI, TM-30), and chromaticity coordinates (x, y), allowing you to quickly check the values on site. With the SEKONIC LD App installed on your smart device, remote measurements are easily achieved via Bluetooth connection. The app allows you to remotely trigger measurements, view numerical values and intuitive graphs of the results, and import stored data from the C-4000 to your smart device.
Caractéristiques
Compact, portable and ergonomic design
Responding to the demands of lighting designers and location technicians/ installers, the C-4000 provides a compact and portable spectrometer, that offers an impressive array of features in an ergonomic design. Two conveniently positioned physical buttons accomplish power on /off and accurate measuring operation. All other settings and mode selections are easily made via the color touch screen. A built-in USB type C connector port, provides designers/technicians quick and easy firmware updates via a connectivity cable to the PC utility providing the latest features, modifications and enhances keeping the C-4000 always at the cutting edge of lighting control.
Simplified and clear displayed screen information
Utilizing a color touchscreen display, the C-4000 provides various numerical measurement values such as Lux, Tcp (Color temperature), ∆uv, CRI (Ra), TM-30(Rf, Rg), and CIE 1931 (x, y) in an easy-to-read display panel in the meter. Quick and ease numerical values can be checked and confirmed on-site in addition to graphs, when the optional smartphone/tablet App is connected via Bluetooth to your smartphone or tablet. Stored measured values in the C-4000 can be displayed in various display graphs including CRI index, TM-30-18, CIE 1931, and other color interruptive illumination languages with the convenience of your smartphone/ tablet. Remote measurements can be made without the risk of the operators, physical shadow corrupting the measurement or for out of reach measuring locations via your smartphone or tablet.
Streamline your workflow with the lighting designer’s dream app: SEKONIC LD Smartphone App
In addition to the C-4000’s ability to take measurements itself, by installing the “SEKONIC LD” standard (included) or advanced (purchased) App on your smartphone/tablet and connecting it to your C-4000 via Bluetooth, you can remotely control the C-4000 Spectrometer. View graphs of stored measurement data, configuration settings and functions remotely and much more on the C-4000 meter via the App. Data, screen shots and images can be shared with offsite designers, engineers, technicians and clients.
