AMS 9000 Goniophotometer – Ideal for variable message signs

Instrument Systems is the right partner if specific goniophotometer solutions are required. An array of customized instruments have been successfully developed and manufactured for variable message signs, signal screens, and very large displays. These are mostly deployed for traffic management during construction work on highways.

AMS 9000 goniophotometer

The special design permits adjustment of very heavy test samples weighing 100 kg or more. What’s more, up to 16 control functions can be operated using the lamp multiplexer. The DSP 10 / DSP 200 Photometer, the CM 10 Tristimulus Colorimeter or a CAS 140CT / CAS 140D Spectroradiometer can be used to take the measurements.

Our long track record of experience in manufacturing customized instruments is at your disposal. We work in partnership with our customers to draw up a detailed specification and provide ongoing support during the implementation and completion of this type of project.
