Recently, entrusted by Shanghai Disneyland, SQI has carried out metrological calibration inspection on the carbon dioxide alarm in the park to ensure their accuracy.

In view of the fact that Disneyland has more visitors during the daytime, the measurement work can only be conducted during the night. The calibration work was finished until 2 am because of the large cover area of the park. Carbon dioxide alarm is mainly used for monitoring the indoor and outdoor gas leak. When the measured presence of toxic gases exceeds the alarm settings, the alarm will sound and light alarm. Thus, the personnel on duty can take safety measures to avoid burning explosion.
