The newly developed NAP-508 electrochemical CO sensor is a consumer electrochemical CO gas sensor with a longer life than the conventional NAP-505 sensor. The shape and dimensions are exactly the same as the conventional NAP-505 sensor, but the cap is dark blue to distinguish it from the conventional product. Based on the results of accelerated life expectancy prediction tests, the sensor is expected to last approximately 12 years under actual usage conditions. It has excellent performance, and can be installed in general home appliances and fire alarms that have not been installed until now. Due to the high heat resistance of the plastic material used, it can also be installed in exhaust gas monitors of latent heat recovery type combustion appliances.
