Specification:

 

OCS2

Miniature High Flow rate  any Oxygen sensor. OCS2 is powered by 8V to 35V / 7mA Unregulated DC Power Supply. OCS2 outputs: UART & 0-5V DC O2 concentration proportional output. Thermal characteristics allow automotive, high altitude and other high Flow rate Oxygen concentration measurement applications. No Flow Alarm output can serve to detect condition of No Flow.
