Cx Plus Monitor

The Cx Plus Monitor™ is a power quality monitor adapted specifically for the needs of a commissioning agent. 

 

The monitor gathers all of the voltage and current data required for all of the commissioning tests as well as provides a means for gathering wireless T/H and DC voltage data for one hundred (100) locations! The Cx Monitor™  is equipped to simultaneously monitor in real time, voltage on ten (10) separate channels and current on five (5) separate channels. This is ideal for documenting the testing of generators, UPS’s and transfer switches.
