Industrial Nitrogen Dioxide Monitor – Reliable NO₂ Detector for Air Safety

Nitrogen Dioxide Area Monitor (PN: 236) is a colorimetric indicator for the detection of traces of nitrogen dioxide gas in air. Suitable location positions for the area monitor are on stack, duct, vent, or flue where representative samples can be obtained.

What is Nitrogen Dioxide (NO₂)?

• Belongs to a group of highly reactive gases called nitrogen oxides (NOx)
• Related compounds include:
  • Nitric oxide (NO)
  • Nitrous acid
  • Dinitrogen tetroxide (N₂O₄)
  • Nitric acid
• NO₂ is commonly used as the key indicator gas when monitoring the broader NOx group

Health Hazards of Nitrogen Dioxide

• Breathing air with high concentrations of NO₂ can:
• Cause respiratory irritation
• Lead to lung inflammation
• Exacerbate conditions like asthma or bronchitis
• Continuous exposure is especially dangerous in industrial environments and diesel engine areas

Primary Applications

• Used as a Nitrogen Dioxide detector in:
• Workplace area monitoring
• Industrial flue gas and diesel exhaust testing
• Chemical and power generation plants
• Helps detect nitrogen oxides, particularly in hazardous emission zones

Why Choose This NO₂ Detector?

• High sensitivity and selectivity to nitrogen dioxide gas
• Ideal for placement in stack, duct, vent, or flue monitoring systems
• Supports regulatory compliance with air quality standards
• Effective as both a nitrogen dioxide monitor and part of broader nitrogen gas detection systems
