Calibration Gas Cylinders
Calibration Gas Cylinders hold traceable gas mixtures used to calibrate industrial gas detectors on a regular schedule. They differ from ordinary gas cylinders by an analysis certificate confirming the mixture and its accuracy. Essential to maintain the accuracy of every gas detector in service and to confirm sensor validity.

About this category
Calibration gas cylinders are the foundation that every gas-detection system relies on to maintain reading accuracy. The principle: a gas detector produces readings that drift over time with sensor aging and thermal exposure; periodic calibration with a known-concentration gas sets the reading back to true. Typical contents: zero gas (clean air free of the target gas, to set the zero point), span gas (a gas at a known mid-range concentration to set sensitivity), and multi-gas mixes (several gases in one cylinder to calibrate multi-gas detectors at once). Mixtures and concentrations vary by the target detector model and manufacturer requirements. Cylinder sizes are available in a broad range to suit limited use, laboratories, and large service centers. Shelf life: cylinders carry a defined expiry date on the label, after which the mix changes by reaction with the cylinder wall. Store upright, at moderate temperature, out of direct sunlight, per the manufacturer's instructions. Applications: service of all industrial gas detectors, laboratories, manufacturer service centers, HSE teams, and large oil and gas facilities. An important technical note: using expired or unverified calibration gas corrupts the calibration and undermines detector reliability. Gas mixes, concentrations, cylinder sizes, and connection requirements vary between manufacturers — review the product documentation and target-detector requirements before purchase.
