Calibration Gas Cylinders

Sku: P-CALGAS

Calibration gases play a vital role in gas detector maintenance by providing a traceable concentration of hazardous gas, ensuring that sensors respond accurately and alarms function properly. Over time, gas monitor sensors experience calibration drift, causing them to lose sensitivity or become overly sensitive. Regular bump testing and calibration with the correct calibration gas helps maintain accuracy, reliability, and compliance with safety regulations. 

Calibration gas is stored in pressurized metal cylinders and used with a pressure regulator and tubing to expose the sensor to a known gas concentration. The detector should match the concentration listed on the cylinder, confirming its functionality and accuracy. 

Why Do Gas Detectors Need Calibration? 

• Prevents inaccurate readings due to calibration drift 
• Ensures compliance with safety regulations 
• Verifies alarm response for hazardous gas detection 
• Maintains worker safety in industrial environments 

Understanding Calibration Gas Cylinders: Shelf Life & Storage 

Calibration gases have a limited shelf life (6–36 months), as gas concentrations can change over time. Proper storage is essential to maintain gas stability and ensure accurate calibration. 

Best Practices for Calibration Gas Storage & Usage 

Store in a cool, dry, and ventilated area, away from heat sources Keep cylinders upright to prevent valve damage Check for leaks, damage, or corrosion before use Use before expiration date for accurate calibration Dispose of expired cylinders according to local regulations
