B Hagner AB was founded in 1962 by Bo Hagner who, at the time, was head of the lighting laboratory at the Royal Institute of Technology in Stockholm. During the last 15 years or so there has been a growing interest for the control of lighting inside road tunnels, i.e. to balance the light inside the tunnels to the light to which an approaching car driver's eyes are adapted. For this purpose, B Hagner AB developed a Tunnel Photometer measuring the luminance at tunnel entrances, according to CIE recommendations, as well as a PLC program for regulating the tunnel lighting. One of the latest products is the ERP-105 luminance meter which can measure levels as low as 0.00001 cd/m². This was developed to meet the requirements for control measurements of the photo luminescent materials used in ships' escape routes. As a manufacturing and development company tries to respond to various photometric measuring needs in the market. Beside tunnel photometers and light sensors, which are for stationary outdoor use, the main aim of the company is to provide the market with reasonable priced, hand held, reliable and accurate photometric instruments, for use in the field as well as in the laboratory. The continuous work of improving existing instruments, together with the development of new instruments has given B Hagner AB its present strong market position.
Hagner provides the following products:
•Illuminance meters
•Luminance meters
•Combination Instruments
•Special instruments
•UV- & IR instruments
•Tunnel photometers, PLC & accessories
•Light sensors
•Special detectors
