NDIR gas analysis - optical measurement technology 

Applications:

• Medicine (patient monitoring, anaesthesia)
• Ambient technologies (green house gases)
• Agriculture (glass house gases)
• Security (mining)  
• Applicable at temperatures up to 190°C and sterilizable

Pyrodetectors have

• High sensitivity and short thermal time constant
• Low microphonic effect and high temperature stability

Single thermopile detector - simple sensor element to detect one gas

Dual thermopile detector - reference channel to detect smoke and dust.

Dual and Quad thermopile and pyrodetectors - available for ambient temperatures up to180°C

Quad thermopile detector - measurement of up to three gases at once plus reference channel
