Feature

NP1011 is aspiration type CO2 monitor. It can monitor the place which can not be installed CO2 monitor directly. Since a measurement display is implemented with CO2 concentration control function, of course and the main part has splash-proof structure (IP33C), it is ideal for a vinyl house and use of a mushroom cultivation facility etc.
