GASTEC High-Precision Flow Meter CG1-13
The GASTEC CG1-13 is a high-precision flow meter designed to accurately measure air flow rate during compressed breathing air testing. It works alongside the GASTEC Compressed Breathing Air Measurement Kit CG-1, which simultaneously checks for CO, CO2, water vapor, and oil mist in breathing air supplied from a cylinder or compressor. The CG1-13 comes with a rubber hose connection and covers two flow ranges for flexible, accurate sampling.
Covers both 200 mL/min and 5 L/min ranges for flexible sampling needs.
Built specifically to support accurate CG-1 breathing air quality checks.
Connects easily via rubber hose for quick setup in the field.
Delivers accurate flow measurement to support reliable test results.
Lightweight design makes it easy to include in your testing kit.
Backed by GASTEC's proven manufacturing standards for lab and field equipment.
Attach the flow meter to your CG-1 breathing air measurement kit using the rubber hose connection.
Choose the appropriate flow range, 200 mL/min or 5 L/min, based on your testing requirement.
Begin airflow from the cylinder or compressor and read the flow rate directly off the meter to confirm sampling conditions.

Clear visual scale provides instant, precise flow verification without requiring electrical power.
Durable rubber hose absorbs line vibration and ensures completely gas-tight connection to CG-1 manifold.
Engineered specifically to accompany the CG-1 kit for measuring CO, CO2, moisture, and oil mist.
Covers both 200 mL/min and 5 L/min ranges for flexible sampling needs.
