Plum data logger MacREJ 5 polycarbonate housing

The MacREJ 5 data logger is a device monitoring the operation status of gas stations and their components. MacREJ 5 records input and output pressure, temperature, and gas volume, monitoring the operation of regulators and safety devices. MacREJ 5 is an intrinsically safe device that can be installed in the zero explosion hazard zone. The device with a built-in modem, when powered by an external power source, allows online access to data. When operating on batteries, it transmits data according to a schedule and in case of an alarm state.
