The CEM GD-3803 is a 4-in-1 multi-functional gas measurement device, 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.
-
Datalogging: Capability to store and record readings for later analysis and tracking changes in gas levels over time.
-
Safety Alerts: Equipped with audible and visual alarms that activate when gas levels exceed defined safe limits.
-
Clear LCD Display: Large screen displaying all readings simultaneously with backlighting for operation in dark conditions.
-
USB Interface: Easy transfer of recorded data to a computer for documentation and reporting.
-
Practical Design: Durable structure, easy to carry and use in the field for extended periods.
