Transient Recorder and Power Meter With Advanced Power Quality and Communication

Electro Industries/GaugeTech The Leader in Power Monitoring and Control

IntroductionFrom today’s utility giants or Fortune 100 companies, to local

electrical municipals, an effective energy management and power

monitoring program is critical to success. The Nexus® 1500 meter

is the most advanced monitoring product on the market today,

providing you with the total picture of energy usage and power

quality from any metered point in a power distribution network,

allowing you to make power related decisions quickly

and effectively.
