Frequently Asked Questions

What exactly does the BreaEzvi 6-in-1 monitor measure?

The device monitors CO2 levels (0-5000ppm), temperature (-10°C to 50°C), humidity (20-95% RH), PM2.5, PM10, and TVOC (Total Volatile Organic Compounds). Each parameter is displayed clearly on the large LED screen.

How accurate are the measurements?

BreaEzvi uses laboratory-grade sensors with ±50ppm accuracy for CO2, ±0.3°C for temperature, ±3% for humidity, and ±10% for particulate matter. The device self-calibrates every 24 hours for optimal accuracy.

What do the different color indicators mean?

Green indicates excellent air quality, yellow shows moderate conditions, orange indicates poor quality requiring attention, and red signals dangerous levels requiring immediate action. Each color corresponds to specific measurement thresholds.

How is historical data tracked?

The device stores 24 hours of data internally. When connected to the optional BreaEzvi app (iOS/Android), it can store up to 30 days of historical data for trend analysis and reporting.

What's the power consumption and backup options?

The device uses 5V USB power (adapter included) and consumes only 2.5W. The optional backup battery (2000mAh) provides up to 8 hours of continuous operation during power outages.

How does the alarm system work?

Visual alerts appear on screen, and an audible alarm sounds when any parameter exceeds set thresholds. Alarm thresholds are customizable, and the sound can be muted during night hours (22:00-07:00).

What's the recommended maintenance schedule?

Clean the sensor openings monthly with the included brush. The PM2.5 sensor should be calibrated every 6 months using the auto-calibration function. Sensors typically last 3-5 years with normal use.

How does the wall mounting system work?

The included mounting kit uses damage-free adhesive strips or screws (both included). The mount allows for easy removal for cleaning while maintaining a secure hold. Installation typically takes less than 10 minutes.
