Technical Features
- Color temperature and illuminance are determined as a means to plot and evaluate lighting systems.
- Compact sensor, particularly suitable for mobile applications
- Continuous measuring and updating of measured values
- Digital color temperature sensor with „TrueColorSensorchip“ and integrated signal processor
The TrueColorSensorchip (3 sensors on 1 chip) detects – separately – each of the three colors – red, green, blue (RGB). The respective sensitivities of these 3 color sensors are adapted to the standard spectral curves as per CIE and DIN. (see Figure)
On the basis of these RGB values the computer calculates the color point within the RGB range in terms of coordinates X and Y and determines the correlated color temperature (CCT) in Kelvin. - The display shows simultaneously both this color data and the illuminance in lux (lx) or kilolux (klx).
- Freely selectable measurable variables
Two measuring channels are programmed (at our factory):
Color temperature (CCT, K), Illuminance (Ev, lx)
Other measurable variable can also be selected:
Illuminance (Ev, klx), X-value, Y-value
This device can be configured on a PC using USB adapter cable ZA1919AKUV.
Accessory Information
- Ulbricht integrating sphere, for measuring total radiation from any light source
- Especially suitable for measuring operations on site for light sources that have already been installed. This minimizes interference from extraneous light in the environment.
- Dimensions:
Measuring aperture 13.5 mm
Sphere diameter 40 mm
Housing diameter 44.5 mm, length 44 mm
