Chlorine Dioxide Calibration Gas & Instruments

SpecGas offers ClO₂ calibration gas at low PPM levels (1–100 ppm), mid PPM ranges (above 100 ppm), and custom concentrations upon request. Common calibration points align with OSHA's PEL of 0.1 ppm TWA and STEL of 0.3 ppm. Custom blends can be formulated to meet specific instrument calibration or regulatory monitoring requirements.

ClO₂ calibration gas from SpecGas is available in disposable aluminum and disposable steel cylinders. These are single-use, portable cylinders ideal for field calibration and bump testing. Because ClO₂ is a reactive and corrosive gas, SpecGas applies its proprietary internal cylinder treatment process to ensure mixture stability and extended shelf life.

Yes. All ClO₂ calibration gas blends produced by SpecGas Inc. are NIST-traceable gas standards. This means each cylinder's certified concentration is traceable to National Institute of Standards and Technology reference materials, ensuring the accuracy and reliability required for regulatory compliance, OSHA monitoring, and quality assurance programs.

OSHA sets a Permissible Exposure Limit (PEL) for Chlorine Dioxide of 0.1 ppm as an 8-hour TWA and a Short-Term Exposure Limit (STEL) of 0.3 ppm. NIOSH identifies the Immediately Dangerous to Life or Health (IDLH) concentration as 5 ppm. Regular calibration of ClO₂ monitors using certified calibration gas is essential to maintain compliant, reliable workplace exposure monitoring.

Industries with a critical need for ClO₂ detection and calibration include municipal water treatment plants, pulp and paper mills, food and beverage processing facilities, pharmaceutical manufacturing plants, healthcare and hospital sterilization units, cooling tower and HVAC operations, and cargo container fumigation operations. Each environment uses ClO₂ as a disinfectant or biocide and requires compliant monitoring.

Yes. SpecGas Inc. specializes in difficult-to-produce and unusual specialty gas mixtures that larger suppliers often cannot fulfill. Custom ClO₂ blends at specific concentrations or in unique balance gas compositions can be formulated upon request.
