A calibration system for calibrating a gas detector includes a control unit and a temperature regulation assembly electrically connected with the control, a temperature sensor electrically connected with the control unit, a set of valves comprising a first valve, a second valve, and a third valve, and a feedback conduit. The control unit is configured to determine whether a temperature of the gas detector is within a predefined temperature range and calibrate the gas detector in an instance in which the temperature is within the predefined temperature range.

Method and system for calibrating a gas detector

The gas detector calibration system comprises a control unit, a temperature regulation assembly, a pump, and a temperature sensor. The temperature regulation assembly has an inlet and an outlet, and the pump has a pump inlet and a pump outlet. The outlet of the temperature regulation assembly is coupled to the pump inlet of the pump. The temperature regulation assembly receives ambient air through the inlet, regulates a temperature of the ambient air, and supplies the ambient air to the pump through the outlet. The pump supplies the ambient air to a gas detector for regulating a temperature of the gas detector. The temperature sensor detects the temperature and sends a signal indicative of the temperature to the control unit. The control unit determines whether the temperature is within a predefined temperature range, when within the predefined temperature range, the gas detector is calibrated using a calibration gas.
