Toxic Gas Detection in Parking Garages
Gas detectors in parking garages play a crucial role in ensuring the safety of both vehicles and individuals. These detectors are essential in monitoring and identifying harmful gases such as carbon monoxide (CO) and nitrogen dioxide (NO2), which can accumulate due to vehicle exhaust.
Safety First
Gas detectors are available to activate demand-controlled ventilation in parking garages, tunnels, or other occupied spaces. Typical requirements are to measure the concentration of carbon monoxide (CO) produced by gasoline powered vehicles or nitrogen dioxide (NO₂) produced by diesel- and gas-powered vehicles.
CO and NO₂ are usually measured using electrochemical sensors.
This technology has a number of benefits in parking garage applications.
Unmatched Reliability
Electrochemical sensors have a limited life span, typically requiring replacement every 2-3 years.
VOC (volatile organic compounds) detectors are air quality sensors for garage environments, which detects emissions and other pollutants that can be formed in a garage. For example, carbon monoxide (CO) and unburned hydrocarbons (HC).
VOCs can be detected using semiconductor sensors. Semiconductor, metal oxide sensors have a number of benefits.
Semiconductor sensors can be cross-sensitive to other reducing gases and pollutants, so consideration should be given to this when selecting an installation location.
