Pollution Testing Machine
A pollution machine, specifically a Pollution Checking (PUC) machine, is an electronic device used to measure harmful emissions from vehicles to ensure compliance with environmental standards. It works by analyzing gases like CO, CO2, and HC from the exhaust of petrol, diesel, LPG, or CNG vehicles using advanced technology and high-quality filters to provide accurate readings on pollutant levels. These machines are essential for environmental monitoring and control, used by emission testing centers, workshops, and pollution control stations for vehicles to promote cleaner air.
