HD35 series data loggers in action
Customized data management is crucial for the integrated monitoring of cold stores and laboratories. It must offer both flexibility and security.
The HD35 wireless data logger system offers cold store operators the optimal solution for their requirements. The recorded data from several cold stores and laboratories are collected centrally in a local database and can be accessed and viewed simultaneously from several workstations. In addition, the customer benefits from the visual and acoustic alarms, as well as from the possibility of adding additional data loggers to the overall system as required. This makes the use of GHM GROUP technology a cost-efficient and future-proof implementation.
