The HALO Smart Sensor Health Index provides a real-time indication of the potential risk for the spread of airborne infectious disease in a building.

This Health Index is used to reduce the spread of infection and it utilizes short measurement cycles for fast remediation. The Health Index factors are:
• Carbon Dioxide (CO₂)

• Particulate Matter (1 μm, 2.5 μm, 10 μm)

• Humidity (RH)

• Total Volatile Organic Compounds (TVOC)

• Nitrogen Dioxide (NO₂)
