Exhaust Detector / Auto Parts

Exhaust Detector is a device designed to measure the hydrocarbon content of the vehicle exhaust. With special coating painted on the surface of the flexible material, its color will change with the hydrocarbon content in the exhaust; namely, it will turn from green to ‘warning’ yellow while the exhaust is bad enough to harm the environment. And its concise profile will also help to lead an environmentally friendly fashion and promote the concept of low-carbon.
