Emission Monitoring Designed to Support Regulatory Compliance

Environmental regulations mandate continuous emissions monitoring for industrial facilities. Environmental gas sensors provide documented measurements to support regulatory reporting requirements while helping you improve pollution control equipment performance and reduce emissions.

 

  • Stack gas analyzers track NOx, SOx and particulate emissions to support air permit compliance monitoring. 
  • Manufacturing plants monitor VOC emissions from coating and drying operations. 
  • Power generation facilities measure CO2 and mercury emissions under Clean Air Act requirements.  
  • Wastewater treatment plants track discharge parameters to meet NPDES permit limits.

Environmental Sensor Frequently Asked Questions

Temperature sensor selection starts with measurement range and response time requirements. RTD sensors and temperature probes support wide ranges from cryogenic to high-heat environments. 

 

Environmental conditions drive housing selection. Sensors may need to withstand shock, vibration, humidity and corrosion in industrial settings. Output options include platinum or silicon-based RTDs, thermistors or thermocouples, depending on control system requirements. 

Gas sensors detect NOx, SOx, CO2, VOCs and other regulated compounds to support compliance with air quality permits. More than 300 sensor configurations monitor 28 different gases including combustible gases, carbon monoxide and hydrogen sulfide for workplace safety.

 

Near-real-time detection capabilities integrate with building automation and industrial control systems to streamline compliance efforts. Continuous  monitoring helps facilities demonstrate compliance with OSHA, EPA and Clean Air Act requirements.
