The CEM GD-3803 is a multi-function 4-in-1 gas meter, designed for high-accuracy air quality monitoring. The device measures and records four essential elements simultaneously: Oxygen (O2), Carbon Monoxide (CO), Carbon Dioxide (CO2), in addition to temperature and humidity, making it a comprehensive tool for ensuring safety in professional and industrial environments.
Key Features:
-
Five-Element Measurement: Continuous monitoring of O2, CO, CO2, temperature, and relative humidity in one device.
-
Data Logging: Ability to store and record readings for later analysis and tracking changes in gas levels over time.
-
Safety Alarms: Equipped with audible and visual alarms that activate when gas levels exceed specified safe limits.
-
Clear LCD Display: Large screen showing all readings simultaneously with a backlight for working in low-light conditions.
-
USB Interface: Easy transfer of recorded data to a computer for documentation and report generation.
-
Practical Design: Durable, portable structure for long-term field use.
