GD-3803: Comprehensive Air Quality and Combustion Analysis in One Device
Master indoor air quality and combustion safety with a single, powerful tool. The GD-3803 is a professional 4-in-1 multifunction gas meter designed to simultaneously measure and log five critical parameters: Oxygen (O₂), Carbon Monoxide (CO), Carbon Dioxide (CO₂), Temperature, and Relative Humidity. Featuring high-accuracy sensors, adjustable alarms, and PC software for data analysis, it is the ultimate instrument for HVAC diagnostics, industrial safety, indoor air quality (IAQ) assessments, and combustion efficiency testing.
