Calibration - Multi-Gas (O2, CO, H2S, LEL)

Features:

Multi-gas calibration is the process of testing and adjusting a multi-gas detector to ensure its sensors are accurate, which is crucial for worker safety.

Calibration involves a two-step process: performing a zero calibration in clean air to set the baseline, and a span calibration by exposing the device to a cylinder of known gas concentrations to align the readings.

This should be done regularly, and especially after events like the device being dropped or exposed to water, to correct for sensor drift and environmental factors.
