Portable carbon dioxide meter AZ 7752

AZ 7752 meter is a digital, portable device designed to control the level of carbon dioxide (CO2) with simultaneous air temperature measurement.

It has a built-in NDIR sensor that allows for precise measurement of CO2 levels in real time. The measurement results are shown on the LCD display in ppm (parts per million). User can set the CO2 alarm threshold after exceeding which the sound signal will be activated and change the temperature reading units (°C or °F).

Device can work in the measurement mode of current values, minimum / maximum values ​​(MIN and MAX functions) and average values ​​for 8h and 15min time intervals (TWA and STEL functions).

HOLD button makes it possible to stop the indications with a quick response. Observation, archiving and printing of the measured parameters can be done via a PC after prior software installation (not included). The device has the function of automatic calibration of the CO2 sensor. The backlit LCD panel makes it easy to read the indications in low light conditions, e.g. at night or in poorly lit rooms.

AZ 7752 can be powered by 4 x 1.5V alkaline batteries or via a DC 9V 1A power adapter. Additionally, it has an automatic cut-off function after 20 minutes. idle and low battery indication.

APPLICATION
The 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.
