1 – Are the Analyzers and Smokemeters MCTCNET2-type approved?

All of the Brain Bee analyzers and smokemeters will be MCTCNET 2 – type approved as soon as the Ministry will be able to do it (probably not before October 2010). New tools will be released with MCTCNET 2 type-approval, while the tools sold earlier will have to be fitted with a hardware key and a new software. Costs will be in any case quite low.


2 – Can the gas line be interfaced with Bluetooth?

Yes, in several ways, in any case always with the introduction of the Bluetooth BT100 modules. A tool configuration with PS170 supplier module is also available making the whole setup completely independent and wireless.


3 – Does it require special maintenance?

The manufacturing quality and the selection of materials give Brain Bee tools excellent operating reliability.


Its small, compact size and 12 V d.c power supply mean it can be used as a portable tool in situations where this is necessary, held by its comfortable, ergonomic handle.



like other tools of the line, the OPA-300 opacimeter can be integrated in the different BRAIN BEE emissions control configurations, providing the end user with his own control station to meet his every requirement.

It can also be integrated in existing stations (on a Brain Bee trolley) demonstrating that restyling will not affect the performance of stations of those already working with Brain Bee tools.



In accordance with Decreto DM/628 and successive circulars, OPA-300 enables you to carry out the official test in the vehicle inspection procedure.
