GVIEWIN MT25 Air Detector — CO2 TVOC HCHO Monitor

GVIEWIN MT25 Indoor Air Detector — CO2, Temperature, Humidity, TVOC, HCHO Monitor

See exactly what you're breathing at home. Multi-sensor indoor air quality monitor that tracks CO2, TVOC, HCHO (formaldehyde), temperature, and humidity in real time. A clear color display tells you when to open a window, run the air purifier, or just relax.

Imagine working from home and finally understanding why you get sleepy by 3 p.m. — the GVIEWIN MT25 sits on your desk, the CO2 number creeps up to 1400 ppm, and you crack the window. Twenty minutes later, the display reads 700 and your brain feels lighter. You see the formaldehyde climb when you sand a project, watch humidity drop when the furnace runs. Your home, finally measurable.
