Application

Application of 77232 AZ CO2 Meter:

The 77232 AZ Wall Mount CO2 Humidity Detector could measure the indoor air quality (IAQ) index, including

the CO2 concentration, CO2 level, air temperature, dew point, wet bulb temperature and humidity. The Carbon

Dioxide value can be output to PC for on-line analysis via USB interface. And it can be calibrated easily in the

fresh air.

Poor indoor air quaintly is considered unhealthy because it causes tiredness, loss of ability to concentrate, and

even illness (ex: sick building syndrome). IAQ monitoring and survey, especially on CO2 level and air ventilation

become widely applied in public areas such as office, classroom, factory, hospital, work space, residential,

commercial building and hotels. It is also s ested in regulations of industrial hygiene in some countries.

The 77232 AZ CO2 RH Thermometer Devicehas the relay function, which could transfer the signal to control the

other equipments. The 77232 AZ CO2 Temperature RH Meter has the stable NDIR CO2 sensor, and it is the ideal

instrument for IAQ diagnosis. Its big LCD could be the best CO2 Monitor for long term monitoring. User could

use the relay function to control or transfer the data to the following related instruments. And the built-in alarm output is especially helpful in ventilation control and HVAC system performance verification.
