Chlorine (Cl2) is a powerful, highly toxic, and corrosive oxidising gas widely utilised in municipal water and wastewater treatment, chemical manufacturing, pulp and paper production, and industrial disinfection. Because even low concentrations can cause severe respiratory distress and chemical burns, maintaining precise and immediate gas monitor response is an absolute requirement for worker safety. Single-gas Chlorine gas cylinders provide gas at thresholds and sensor sensitivity against hazardous exposure limits.

Due to Chlorine’s highly reactive and adsorptive properties, standard steel or untreated containers cannot maintain the integrity of the gas mixture. All of our Cl2 calibration cylinders feature specially passivated Aluminium construction and treatment, preventing gas adsorption and degradation to ensure long-term concentration stability, shelf-life reliability, and sensor verification. Whether you are utilising compact 34L and 58L portable Aluminium cylinders for mobile water treatment checks or deploying 116L capacities for ongoing maintenance of dedicated single-gas monitors like the GasBadge Pro, our Chlorine solutions deliver the uncompromised stability required in corrosive industrial environments.
