Our opacimeters for diesel engines are small and compact. With their 12-v power supply, these portable units with comfortable, ergonomic handle are ideal for use on the go. The OPA-300 is designed for extreme flexibility and ease of use. It can be connected to a PC via a normal serial interface (RS-232 or RS-485). Since it has its own OMNIBUS-800 software, it can guide even inexperienced users safely through the emissions testing process.

Guaranteed Modularity
Like many other devices in this series, the OPA-300 opacimeter can also be incorporated in various BRAIN BEE emission control configurations, enabling users to set the testing station up based entirely on their individual requirements. It can also be integrated in existing stations (on a BRAIN BEE trolley), and therefore fits in harmoniously and stylistically in workshops that use BRAIN BEE equipment.
