Dual Gas Sensors

Dual Gas Sensors (SOH-A2, COH-A2 and D2)

• SO₂ / H₂S the SOH-A2 measures the two critical Sulfur gases together within one sensor body and using a software algorithm, separates the two gases for clear discrimination.
  
• CO / H₂S the COH-A2 builds on 10 years of experience with our original D2 sensor.

… and coming soon

NO₂ / O₃ the NOO-A2 determines the two important oxidising gases for air quality monitoring.
