Temtop Air Quality Monitor PM2.5 AQI Meter Temp Humidity Detector Home / Office

PRODUCT SPECS

Condition description & Additional Information (If Applicable)

Brand new, still in original box (box may be slightly damaged) Opened for testing purpose. Item may have some slight dust from storage. Any questions, please ask.

Vibrant LCD Display with Color-Coded Air Quality Bar: This model features a high-contrast color LCD screen (not an e-ink display) that shows PM2.5, AQI, temperature, and humidity at a glance. The intuitive color bar changes from green to red to help you instantly understand your indoor air quality status (Good/Fair/Poor).
Two Working Modes for Your Needs: ECO Mode extends battery up to 60 days for long-term monitoring with less frequent sampling; A Mode (Smart Mode) provides up to 20 days battery life with more frequent sampling for better real-time awareness—simply single press the setting button to switch between modes.
Flexible Temperature Display: Long press the setting button for 2 seconds to toggle between Fahrenheit (℉) and Celsius (℃) based on your preference.
Real-Time Response You Can Trust: Equipped with a professional-grade laser sensor, the S1-up detects PM2.5 particles instantly—watch readings change as you open a window or light a candle. Worried the display isn't updating? ECO mode samples less frequently to extend battery life; simply switch to A Mode for continuous monitoring, or keep it plugged in for uninterrupted real-time tracking.
Breathe Easy, Live Healthy: You can't see PM2.5, but it can impact your family's well-being. The S1-up gives you the visibility you need to take action. Use it to check if your air purifier is actually working, know exactly when to air out the kitchen after cooking, or ensure your baby's nursery has optimal air quality for sleep. It’s not just a monitor; it's your family's first line of defense against invisible pollutants.
English Manual & Technical Support: The English manual is included in the package. If you have any questions about mode settings or device operation, please contact us via Amazon's messaging system—we typically respond within 24 hours.
