Car park gas detector calibration adjusts and verifies the accuracy and performance of a gas detector or gas monitor. Detectors detect and monitor hazardous gasses in various environments, such as industrial workplaces, laboratories, and confined spaces. Calibration ensures that the gas detector provides reliable and accurate measurements of gas concentrations.

During calibration, the concentration of a targeted gas is introduced to the gas detector, and its response is then compared to the expected or reference value. The calibration process involves adjusting the sensor's sensitivity or signal output to match the known gas concentration, effectively aligning the detector's readings with the actual gas levels.
