Specification:

 

OCS1

Miniature any Oxygen & Flow Rate sensor. OCS1 is powered by 8V to 35V / 7mA Unregulated DC Power Supply. OCS1 outputs: UART & 0-5V DC O2 concentration & Flow Rate proportional outputs. Thermal characteristics allow any Oxygen concentration measurement. No Flow Alarm output can serve to detect condition of No Flow.
