Sensors
The sensors illustrated below have been designed to
measure the apparent intensity of visible light (lux), ultra-
violet light (UVA and UVB) as the relative colors of red, 2872.00
green and blue light (RGB). The sensors are supplied
with a 5-pole DIN connector and require a +5 VDC pow-
er supply. The sensors can be connected to computer
interface system or to an ordinary voltmeter via battery
box no. 2515.60.
UVA sensor, directional
Useful for the investigation of the emission from the sun,
from halogen lamps, from solarium lamps etc., and the
investigation of how UVA-intensity changes with distan-
ce. The measurement of light with the wavelength 370
nm +/- 5 nm only is ensured by a narrow band filter.
Provided with 5-pole DIN connector. (Requires a +5 VDC 2872.01

power supply.). Dimensions: diameter 24 x 99 mm.
2872.00 UVA sensor, directional
UVA sensor, table model
For the same uses as no. 2872.00, but designed as a
table model.

Supplied with a teflon diffuser to detect light from all
directions. Dimensions: Height 50 mm. Diameter: 60 mm.
2872.01 UVA sensor, table model
UVB sensor, table model
This sensor has been designed to follow the CIE respon-
se curve for reddening of the skin (erythemal response
curve) in the UVB spectral region.
The sensor is therefore suitable for measuring the UVB-
dose and subsequent evaluation of the risk of skin can- Lux sensor, table model
