Frequently asked questions
What is the difference between a bump test and a calibration?
A bump test applies gas briefly to confirm the sensors respond and the alarms activate. A calibration applies a known concentration and adjusts the instrument reading to match. A bump test proves it reacts; a calibration proves it is accurate.
How often should a gas detector be bump tested?
Manufacturers and industry guidance generally call for a bump test before each day of use, with full calibration at the manufacturer-specified interval.
Does calibration gas expire?
Yes. Cylinders carry an expiry date and the concentration drifts as they age. Calibrating against expired gas produces an instrument that reads confidently but incorrectly.
How long do gas sensors last?
Electrochemical sensors have a finite life measured in years and degrade even in storage. The instrument will usually flag a failed sensor at calibration.
Are calibration kits interchangeable between brands?
Rarely. Regulators, caps and tubing are matched to the specific instrument and cylinder thread, and a poor fit leaks gas and invalidates the calibration.
Where do the specifications on this page come from?
They are taken from the manufacturer's published listing. WC Safety does not laboratory-test products, and nothing is claimed here that the manufacturer does not state.
