The IP66 rated Miro-F series of transformer monitors and loggers are designed for distribution transformer monitoring and offer comprehensive monitoring, including three phase voltages, currents, temperatures, THD and Flicker, with various secure communications protocols, e.g. TCP-IP, Dyn DNS, FTP, DNP3 and MQTT.

It has integrated remote cellular communications (3G/4G and optional Ethernet) and is ideal for large scale deployment.

Large scale network monitoring solutions utilising the Miro-F instruments can be implemented to provide network engineers with accurate data for planning, operations, maintenance and network modelling purposes. All data can collected and analysed by AsMoSys, a CHK PQ proprietary database solution.
