GASTEC Pressure Regulator
The CG1 Series Pressure Regulators are specifically developed to maintain stable gas flow during calibration. Designed for use with disposable calibration gas cylinders, these regulators ensure reliability, accuracy, and safety in test environments. Models are available for different flow control needs, fixed or variable, supporting applications in industrial hygiene, safety, and gas detection calibration.
Designed to connect directly to standard disposable calibration gas cylinders.
Choose a fixed flow model for consistency or a variable model for flexible control.
Maintains a steady pressure output, ensuring precise, repeatable calibration results.
Built to hold up under repeated field or lab use without adding extra bulk.
Engineered for consistent performance across demanding test environments.
Suited for industrial hygiene, safety programs, and gas detection calibration.
Secure the regulator to the calibration gas cylinder valve, making sure the connection is tight and leak-free.
For fixed-flow regulators, confirm the required flow rate. For variable models, adjust the knob to the desired flow within range.
Connect the regulator outlet to your detector or sampling equipment, start gas flow, and proceed with calibration.

Internal balancing diaphragm dampens pressure spikes, providing smooth gas delivery to sensors.
Engineered to couple smoothly with standard disposable span gas bottles across GCC industries.
Robust brass alloy construction ensures repeatable performance in rigorous plant inspections.
