Calibration Gas & Regulators

Maintain the accuracy and reliability of your gas detection equipment with premium Calibration Gas & Regulators from Activated Carbon Depot. Proper calibration and routine bump testing are essential for ensuring gas monitors respond accurately to hazardous gases, helping protect personnel, maintain regulatory compliance, and maximize instrument performance.

Our collection includes high-quality calibration gas cylinders, demand flow regulators, fixed-flow regulators, and related accessories compatible with many of today's leading gas detection instruments, including RKI Instruments and other professional gas monitoring systems.

Why Calibration Matters

Gas detectors are precision safety instruments that require routine calibration to verify sensor performance and ensure accurate gas concentration readings. Over time, environmental conditions, sensor aging, and normal instrument use can affect sensor accuracy.

Using certified calibration gas and the proper regulator helps:

• Verify sensor accuracy
• Perform routine bump testing
• Maintain manufacturer-recommended calibration schedules
• Improve worker safety
• Support OSHA and industry compliance requirements
• Extend sensor performance
• Reduce false alarms and inaccurate readings

Routine calibration gives users confidence that their gas detection equipment will respond properly when hazardous gases are present.

Compatible Gas Detection Applications

Calibration gas is commonly used with instruments that monitor:

• Oxygen (O₂)
• Carbon Monoxide (CO)
• Hydrogen Sulfide (H₂S)
• Combustible gases (LEL)
• Methane (CH₄)
• Carbon Dioxide (CO₂)
• Volatile Organic Compounds (VOCs)
• Ammonia (NH₃)
• Chlorine (Cl₂)
• Sulfur Dioxide (SO₂)
• Hydrogen (H₂)
• Nitrogen Dioxide (NO₂)
• Ozone (O₃)
• And many additional specialty gases

Different instruments require specific calibration gas concentrations and regulator types, making it important to select products compatible with your equipment.

Industries We Serve

Calibration gas and regulators are used across a wide range of industries, including:

• Environmental consulting
• Oil and gas
• Water and wastewater treatment
• Chemical processing
• Industrial manufacturing
• Utilities
• Mining
• Construction
• Fire departments
• Emergency response
• Food and beverage processing
• Pharmaceutical manufacturing
• Laboratories
• Municipal facilities

Whether you're performing daily bump tests or scheduled instrument calibrations, using quality calibration products helps ensure dependable gas monitor performance.

Choosing the Right Regulator

Selecting the correct regulator is just as important as choosing the proper calibration gas. Demand flow regulators automatically deliver gas when the instrument draws a sample, while fixed-flow regulators provide a constant flow rate for instruments that require continuous gas delivery.

Our team can help you identify the correct regulator based on:

• Gas monitor manufacturer
• Calibration gas cylinder type
• Required flow rate
• Instrument calibration procedure
• Application requirements
