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.
