Gas Standards for Explosive Concentration Monitors
Gas standard mixtures are an accurate method for calibration of explosive concentration monitors. They are stable and provide a repeatable reference concentration that can be used for regular calibrations.
Each gas standard contains accurately-weighed component.
Mixtures are available for explosive concentration monitors with the following components:
The compositions listed are 50% LEL
Amount Fraction Range
NPL's gas standards are certified for a period up to five years depending on the stability of the mixture. NPL offers a cost-effective re-certification service after the initial certification period has expired, ensuring temporal consistency of gas traceability.
