How frequently should the gauge used to set the regulated source of pressure be calibrated?

The gauge used to set the regulated source of pressure should be calibrated annually to ensure accurate measurements and functionality. Calibration is a critical process in maintaining the precision and reliability of measuring instruments, which is essential in applications involving fire extinguishers and other safety equipment.

Annual calibration aligns with industry standards and best practices, which emphasize the importance of periodic verification of equipment to ensure it operates within specified tolerances. This frequency helps in identifying any drift or inaccuracies that may develop over time due to wear and environmental factors. By calibrating the gauge once a year, technicians can ensure that the pressures used in maintenance and operation remain consistent and safe, ultimately contributing to the effectiveness of fire extinguishers when they are needed. Regular calibration is vital for compliance with safety regulations and standards in the fire protection industry.
