Nano 3 sensors are designed to respond to Carbon Monoxide, they will also respond to some degree to other gases. The table above is not exclusive and other gases not included in the table may still cause a sensor to react. The cross-sensitivity data shown above does not form part of the specification and is supplied for guidance only. Values quoted are typical for the Nano 3, individual cells may show a small degree of variation

The technology and chemistry involved in the design and manufacture of electrochemical carbon monoxide sensors can fail to meet specification without warning. While Pace Sensors Limited make every effort to ensure the reliability of the sensors, we recommend that all sensors and products incorporating sensors are checked for response to gas before use.
Note: All measurements taken at 25°C at a humidity of between 30% and 50% rH and at atmospheric pressure unless otherwise stated. All measurements made on cells less than 6 months after manufacture
