portable vehicle CO gas detecting alarm with long lifetime

paper box

This vehicle co gas alarm can detect the co gas concentration in the car enviroment, and make sound and light alarms when the ambient concentration is over the warning values, then prevent users from co gas damages. ( detailed alarm values, please see the Alarm concentration) 

This device couldn’t be used to detect the natural gas (methane ), propane, butane or other combustible materials.  Designed by professional engineers, its unique and attractive appearance is harmonious with the whole vehicle cars. 

Suggestion for the using place:

Can be hang on the car rearview mirror or fixed to other places which is out of driver’s slight.
