NEMO - Model 332 - Portable Power Quality Analyser
From Portable Analysers
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.
