Click2Contact

YESair is a sophisticated, multi-sensor air quality monitoring and information recording instrument. It simultaneously measures and records temperature, relative humidity and CO₂ levels in the air. It also measures and records the levels of four more gases with additional specific plug-and-play sensors.

The instrument has a wide assortment of sensors. All seven sensors are installed internally and an air sample from the target environment is delivered to them through active sampling by the internal sample pump.

The LCD indicates all installed sensor types and measured values for each gas, as well as battery status and other information. The instrument will operate continuously from the supplied wall adapter/battery charger. The user can also set one alarm level for each gas to activate the internal audible alarm.
