AZ 7732 Carbon Dioxide Temperature Humidity Meter

AZ 7732 Carbon Dioxide Temperature Humidity Meter | Works with Batteries Only

• Multi-Parameter Tracking:
The AZ 7732 device is an advanced desktop analysis device that can simultaneously measure essential air quality parameters such as carbon dioxide (CO₂), relative humidity, air temperature, and dew point.

• Long-term Operation with Batteries:
Unlike similar models, this device operates only with 3 AAA batteries and does not require an adapter. With its structure that provides extraordinary power savings, it offers continuous operation for approximately 1 year in Eco mode and approximately 6 months in Regular mode.

• Two Different Operation Modes:
– Eco Mode: Data is updated every 1 minute. Battery life is 1 year and above.
– Regular Mode: Data is updated every 10 seconds. Battery life is approximately 6 months.

• Displaying Environmental Quality with Colors and Facial Expressions:
The air quality of the environment is visually presented to the user on the LCD screen with green, yellow, and red colors and facial expressions:
– Green (Good): CO₂ < 800 ppm
– Yellow (Moderate): 800–1000 ppm
– Red (Poor): > 1000 ppm

• Audible and Visual Alarm:
When the CO₂ value exceeds 1000 ppm, the device emits a loud beep at 2-second intervals. The sound can be muted with the Mute button, but the alarm icon on the screen continues to flash.

• Carbon Dioxide Measurement Technology:
The device uses high-sensitivity NDIR (non-dispersive infrared) sensor technology.

• Average and Peak Value Display:
With the AVG button;
– The average CO₂ value of the last 8 hours
– The average CO₂ value of the last 24 hours
– The highest CO₂ value (peak) of the last 24 hours can be displayed.

• Security Password and Anti-Theft:
With the password protection feature, the settings section can be secured against unauthorized persons.

• Flexible Installation Options:
– Easy placement with desktop stand
– Can be wall-mounted with hanging hole and mounting bracket.

• Box Contents:
The device itself, 3 AAA batteries, hanging bracket, screws, and English user manual
