NEMO 332
Portable power quality analyser - 4 voltage inputs and 4-32 current inputs - nominal current rate can be selected in range 10-10 000A.
NEMO 332 is a portable multifunctional power meter and power analyser with datalogger functions. It is suitable for low, medium and high voltage networks (measured via voltage transformer). Its large internal memory can store months of typical measurements and also records disturbance data, log, electricity meter reading and other critically important information. It shares many features with its panel counter part SMPQ.
Its enclosure, interfaces and supply power options are optimized for simple installation of this portable datalogger in space constrained environments. NEMO family has a wide variant of communication options including wireless and mobile networks for simple contactless installation and supervision.

ENVIS application suite provides all features for basic instrument management (configuration, supervision, fw update). It also downloads and archives data from all the supported instruments. import/export, data analysis and advanced reporting of the records is also provided. ENVIS is available free of charge to be used with all our instruments.
ENVIS.Online system service can be used to implement complex power quality monitoring and/or energy efficienci control and monitoring systems. By using email, SMS or SNMP all registered users and administrators can be warned upon exeptional situations, malfunction of supply or monitored instruments or it can be used to post periodical analysis/reports.
Additional plugin modules can also add special features or customizations to booth ENVIS and ENVIS.Online in a modular manner.
