Reefer Cargo Temperature Recording

• The data of the status of a reefer container can be continuously and automatically monitored remotely through a lead provided with the power cable of the reefer container.

• Despite the information obtained through a data logger, manual checks on the temperature maintained are carried out daily and recorded in a register.

• Any malfunction is attended by the engineer in charge and a report is made and transmitted to the container receivers agency. Follow-up reports are made till the container is functioning normally or till the container is discharged.
