Hand Held CO Gas Meter With High Quality, Long Lifetime and Battery Operation

This vehicle co gas alarm can detect the co gas concentration in the car environment, 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.
