Product Description
Portable Power Quality Meter GDPQ-300E

General introduction

GDPQ-300E Power Quality Analyzer is a portable device of testing and analyzing power system operation 
quality. It monitors and collects data in long running time, also provides harmonic analysis and power quality analysis. Meanwhile, it equips with data analysis software, by which the measure data can be uploadedto PC.   
l ARM and DSP, 16M byte memory.  
l Touch screen, more easy and convenient.
l Data measure and saving, can be uploaded to PC.
l Module structure, reasonable design and reliable operation.
l Easy and convenient software upgrading. 
l Detailed analysis of measure data by power quality data analysis software in PC.
