PORTACAL® Nitrogen Dioxide (NO₂) Calibration Gas is designed for the calibration, bump testing, and verification of compatible nitrogen dioxide gas detectors, NO₂ sensors, and monitoring instruments.

Nitrogen dioxide (NO₂) is a toxic, highly reactive gas commonly produced during combustion processes. It may be encountered in vehicle and diesel exhaust, power generation, industrial combustion, welding operations, chemical manufacturing, enclosed parking facilities, and other environments where combustion emissions may accumulate.

PORTACAL® Nitrogen Dioxide Calibration Gas provides a known concentration of nitrogen dioxide to help verify that compatible NO₂ sensors, portable gas detectors, fixed gas detection systems, and industrial gas monitoring instruments are functioning and responding properly.

Calibration Gas

• Gas: Nitrogen Dioxide (NO₂)

• Gas Type: Reactive Gas

• Cylinder Material: Aluminum Alloy

• Valve Inlet: 5/8"-18 UNF (C-10)

• Regulator: 71-Series

• Application: Nitrogen dioxide sensor calibration and bump testing

• Compatible Equipment: Appropriate nitrogen dioxide gas detection and monitoring instruments

Common Applications

This nitrogen dioxide calibration gas is suitable for compatible equipment used in NO₂ detector calibration, nitrogen dioxide sensor calibration, gas detector bump testing, diesel exhaust monitoring, combustion and emissions monitoring, power generation, enclosed parking facilities, welding operations, chemical manufacturing, industrial hygiene, environmental monitoring, occupational exposure monitoring, and workplace safety applications.

Always verify the required gas concentration, cylinder connection, flow rate, and regulator compatibility for your specific gas detection instrument before use.

Cylinder Material Notice

Steel cylinders are for non-reactive calibration gases only. Aluminum cylinders are for reactive calibration gases only, regardless of cylinder size. Please verify the gas type and cylinder material when selecting your calibration gas.

Tip: Check the Specifications tab for a visual chart of available cylinder sizes, materials, pressures, dimensions, valve inlets, and regulator compatibility.
