About MacR 6

The MacR6 is made for gas meter data logging in distribution networks. It works well in remote locations with limited mobile network coverage. The tampering detection feature ensures accurate billing and system security.

It has a compact design with a lightweight polycarbonate housing and a segment LCD display that shows diagnostics, counter, increments and peak data. The long-lasting lithium battery helps reduce service and maintenance costs.

You can integrate it easily with SCADA and metering platforms via LPWAN. You can also configure it on-site using a mobile device with the ConfIT! Software.
IECEx Certification
EN 60529 Compliance
M2 / E2 Classification

The MacR6 is a robust data logger built for advanced metering applications in residential, commercial and industrial networks. It supports LTE-M (Cat.M1), NB-IoT and fallback 2G communication to ensure reliable data transfer even in poor network conditions.

The device has reverse flow detection, second-by-second sampling and up to 10 years of storage capacity. It comes with an LTE modem, NFC and Modbus interfaces for easy SCADA or data system integration.

It is certified for use in hazardous areas (Zone 0 and Zone 2) and has IP65/IP66 protection, tamper detection and a diagnostic display for easy field monitoring. The replaceable lithium D-size battery powers the unit for up to 15 years, helping lower operating costs. The MacR6 meets smart metering requirements, integrates with modern billing systems and provides secure and efficient remote data acquisition.
