JEMStar Meters by Ametek

The JEMStar II is often used to measure hundreds of thousands of dollars of electricity revenue at utility generation and transmission substations, and with the industry’s best 0.05% accuracy ensures that all of it is accounted for. The JEMStar II sets an industry first with a large color graphic display for showing real time power values, meter status, site conditions and more.

The JEMStar II has 8 communication ports available, including dual independent Ethernet ports with security to meet NERC Critical Infrastructure Protection (CIP) requirements. The JEMStar II has advanced power quality monitoring to provide quick and easy analysis of system anomalies.

“The innovative, straightforward JEMWARE configuration software makes our meter the easiest one to use” says AMETEK Power Instruments’ Business Manager Steve Bleier. “Most meter technicians can configure our JEMStar II with no assistance required.”
On its industry-leading high accuracy for watt hours, “We were quite impressed with the typical accuracy of 0.02% and users can’t underestimate the importance of this when the JEMStar II is used as a utility’s cash register.”

The JEMStar meter is backed by AMETEK’s 5-year warranty and 10-year accuracy guarantee. In addition to revenue meters, AMETEK offers a comprehensive line of power recording, measurement, and control instruments and sensor systems for gas turbine engines and industrial/utility boilers and burners.
