▸ Shop all disposable calibration gas cylinders
What is disposable calibration gas?
Disposable calibration gas is a single-use, non-refillable cylinder of a precisely known gas concentration, used to bump test and span-calibrate portable and fixed gas detectors. Trigas USA cylinders are NIST traceable, blended in an ISO 17025 certified laboratory to a ±2% tolerance, and use a standard C-10 connection.

Frequently asked questions
What is disposable calibration gas used for?
To bump test and span-calibrate gas detectors so they read accurately. A bump test confirms the sensors and alarms respond; a span calibration adjusts the reading to a known concentration.
Are disposable calibration gas cylinders refillable?
No. They are single-use and non-refillable, designed to be recycled once empty.
How long do disposable calibration gas cylinders last?
Non-reactive blends last up to 48 months; reactive gases (such as H₂S, NO₂, Cl₂) have shorter shelf lives. The expiration date is printed on each cylinder.
Which calibration gas do I need for my gas detector?
Match the gas type and concentration to your detector's sensors. For a 4-gas confined space monitor, use a 4-gas mix (CO, H₂S, LEL, O₂). Contact Trigas USA for an OEM cross-reference if you are unsure.
How much does disposable calibration gas cost?
Single-gas non-reactive cylinders start at $45; 4-gas mixes range $130–$300; reactive gases up to ~$390, depending on size and blend.
Do you ship calibration gas across the United States?
Yes. All cylinders ship Division 2.2 compliant throughout the USA.
