When the purpose of wearing a gas detector or monitor is for it to alert you to possible danger to save your life

Ensuring that it works correctly is imperative.

Gas sensors can drift as much as <2% to <5% per month. This is an undeniable fact for electrochemical sensor technology. The only way to verify that a gas detector is fully functioning and responding to toxic or flammable gas exposure is through routine calibration and functional bump tests.

Calibration of your personal gas detectors ensures your units are fully functioning and comply with legislation and regulations. Gas detection manufacturers recommend calibration at least once every 6 months to ensure the integrity of the gas sensors.
