Optical transmission and reflection measuring systems consist of light source, measuring cell (transmission equipment), filter wheel, measuring head, evaluation unit and connecting cables. A higher-level archiving system or a maintenance PC can be connected via a network connection.

Depending on the measuring task, Pier-Electronic can offer the appropriate optical measuring method. While transmission photometers use the transmission of light as a measured variable, reflection measuring systems evaluate the reflection of the emitted light beam.

The photometers have been developed and manufactured by Pier for more than 50 years. They are extremely easy to use, reliable and durable optical measuring devices.
In-depth user advice and finding optimal solutions combined with good service are self-evident.
More than 4,000 installed measuring systems worldwide prove their quality and emphasize their wide range of possible applications.
