JEMStar High Accuracy Revenue Meter (REPLACED BY JEMStar ll IEC High Accuracy Revenue Meter)
Brand: RIS - Scientific ColumbusJEMStar II Retrofit
We've designed our JEMStar II to fit into an existing legacy meter enclosure, including the JEMStar, and connect to the existing wiring for a plug and play replacement option.
This takes the hassle out of finding a way to fit your new meter into an existing cutout and the extra time to update your drawings and rewire the meter.
Utilizing our retrofit offers you the many advanced features that were not available on previous models and can save you more than $1,000 when compared to the cost of installing new meters.
In addition to the JEMStar, our retrofit is available for the following meters:
- SCI JEM2, JEM10 and JEMStar
- GE DS63, DSW63, DS64, DSW64
- Quantum Q121, Q220
- TransData MarkV
- L&G Quad4
- Westinghouse D2B, D4B
