CO2 Monitor with 4.3inch Color Display, Accurate NDIR Sensor, USB Rechargeable Air Quality Meter

Portable CO2, temperature, and humidity monitor with a 4.3inch color LCD for continuous indoor monitoring. Metal and ABS housing, NDIR CO2 sensing, and a builtin fan provide fast, reliable readings in a compact, rechargeable unit. Key benefits Accurate CO2 measurement: NDIR infrared sensing provides direct CO2 concentration readings from 0 to 5000 ppm. Fast realtime data: 1.5 second sampling time and 24hour continuous monitoring for prompt detection of changes. Representative air sampling: Onboard fan actively draws ambient air into the sensor for more stable and timely measurements. Easy to read: Large 4.3inch color LCD with 320 x 240 pixel resolution and adjustable brightness reduces glare and keeps data visible in different lighting conditions. Portable and long runtime: 2000 mAh lithium battery included, USB charging, and low battery warning for reliable portable use. Durable construction: Metal plus ABS materials deliver a sturdy yet lightweight enclosure suitable for daily use.
