AZ 7722 is a meter designed to monitor indoor air quality.
Adapted for continuous operation using the control function, through the relay output, external devices (e.g. fans, solenoid valves, etc.) or for routine instantaneous measurements.
It allows the simultaneous measurement of carbon dioxide, temperature and humidity. It has a built-in NDIR sensor that allows for precise measurement of CO2 levels in real time and a high-class Rotronic sensor for measuring humidity. Results are presented on a three-field LCD display.
User can set the CO2 alarm threshold after exceeding which the optical and acoustic signaling will be activated, change the temperature reading units (ºC / ºF) and select the values displayed on the LCD panel. Device can work in the mode of measuring current values, minimum / maximum values (MIN and MAX functions) and average values for 8h and 15min time intervals (TWA and STEL functions).
RS232 port enables the connection with a PC in order to save the current indications after prior software installation. Meter has the function of automatic calibration of the CO2 sensor and a two-point calibration of the humidity sensor.
AZ 7722 is powered by a DC 12V 0.5A adapter.
APPLICATION
Meter can be used as the CO2 checker for the air quality index in all workspace, office, hospital, school, station or home. It can be calibrated easily in the fresh air and its back light function could let user operate in the dark area. AZ 7752 is your best choice as the indoor air quality (IAQ) testers.
