Regulatory Content and Methods for Regular Detection of Flammable Gas Detectors
Annual inspections of industrial and commercial alarm sensors are conducted regularly, primarily to check for the accuracy of the alarm readings, repeatability, drift, and response time to ensure they meet standards. Additionally, the suitability of the alarm's installation location and any interference from other equipment are also assessed.

Gas Detector Alarm Calibration Specification Requirements
Regulation 5.5 of the "Procedures for Verification of Combustible Gas Detectors" (JJG693-2011) stipulates: The verification cycle for combustible gas detection and alarm instruments: generally, the verification cycle of the instrument should not exceed one year. If there is any doubt about the measurement data of the instrument, or if the instrument has been replaced with major components or repaired, it should be promptly sent for verification.
Section 3.5 of "Regulations for the Use of Combustible Gas Detection and Alarm Devices" (SY6503-2000) stipulates: In-use combustible gas detection and alarm devices shall be calibrated periodically as required.
Occupational Health and Safety Regulations for the Installation of Toxic Gas Devices in Workplaces (GBZ/T223-2009) Article 7.2.1 stipulates: Calibration of detection and alarm devices shall be carried out regularly according to the manufacturer's specified time and procedures.
Section 3.4 of the "Regulations for the Use of Combustible Gas Detectors" (SY6503-2000) stipulates: Combustible gas detectors for installation and use shall have measurement instruments manufactured by an institution recognized for their **explosion-proof performance**.
