GASCO 105ES-359 Calibration Gas, Methane 50% LEL in Air, 105 L Cylinder

GASCO calibration gas is used to verify and adjust the accuracy of portable gas detectors across industrial safety applications. This methane mixture (50% LEL at 2.5% in air) ensures detectors respond correctly to combustible gas hazards, supporting compliance with safety protocols in refineries, chemical plants, and confined-space entry.

The GASCO 105ES-359 calibration gas contains methane at 50% LEL (2.5% by volume) in an air background, with +/-2% accuracy. It is supplied in a 105 L cylinder and is compatible with all OEM gas detectors. The background gas is air, and the brand is GASCO.

3G Electric supplies GASCO calibration gas worldwide, handling full logistics and customs clearance for international orders. As a global industrial solutions provider, we source and deliver this methane calibration gas (105 L cylinder, MPN 105ES-359) to safety teams and facilities anywhere, ensuring compliance with local import requirements.

To use GASCO calibration gas, connect the cylinder regulator to the detector's calibration port, then apply the gas mixture at the specified flow rate. Allow the detector to stabilize and compare readings to the certified 2.5% methane concentration. Adjust the detector if needed, following OEM instructions. Always store cylinders upright in a ventilated area.
