Monitoring CO₂, fine particulate matter, and other relevant parameters with an air quality meter helps identify changes that may be difficult to detect through human senses alone.

CO2 is colorless and odorless but can accumulate in enclosed spaces. Use a CO2 gas detector to monitor air quality fluctuations and proactively ensure safety.

Elitech iCold is a cloud-based platform designed to support remote monitoring and management across temperature-sensitive cold chain operations.

The E04 error on a refrigerant pressure gauge may be related to abnormal pressure conditions. Electrostatic interference and moisture ingress are two possible causes mentioned in the relevant guidance. When the error appears, continuing to use the instrument may result in unreliable readings. Therefore, it is recommended to stop the measurement and troubleshoot the issue step by step.

A systematic troubleshooting guide for checking a refrigerant pressure gauge that does not respond during the vacuuming process, focusing on connections, reset procedures, and zero-point calibration.
