Heat conduction gas sensor NAP-21A

For consumer
Consumer alarm
Heat conduction type
carbon dioxide

NAP-21A is sensitive to carbon dioxide and inert gas, and can be used even in an oxygen-free environment.Since it is easily affected by changes in temperature and humidity, it is ideal for monitoring the concentration in a closed environment such as an incubator or incubator.

【Feature】

Compatible with various gas types
Can be detected even in an oxygen-less environment
