Household Portable Air Meter S1, S1+, C1 | PM2.5, CO2, Temperature & Humidity

The Household Portable Air Meter Series (S1, S1+, C1) is an advanced generation of air quality monitors combined with hydro-thermometers, offering compact design, precision, and long-lasting performance. S1: Measures PM2.5, AQI, temperature, and humidity with long battery life (up to 100+ days in power-saving mode). S1+: Adds Bluetooth networking to sync historical data and environmental trends for deeper air quality insights. C1: Specially designed for CO₂ monitoring, alongside temperature and humidity detection, ensuring safer indoor environments. Equipped with a Temtop 5th-generation laser PM sensor and Sensirion temperature & humidity sensor, the series guarantees highly accurate readings. The 3.3-inch LCD screen with intuitive Good–Fair–Poor indicators makes real-time monitoring simple and clear.
