The Integra Ri3 Digital Metering System (dms) represents the first model of a new generation
of instruments designed to complement the current Crompton Instruments Integra series.

The Integra Ri3 dms is an accurate and cost effective solution for measurement and
display of all major electrical and power quality parameters. Its easy programming,
mounting and user-friendly navigation make the Integra Ri3 dms an ideal choice for
customers who require reliable energy management.

The Integra Ri3 dms is built to high quality standards utilizing the latest microprocessor
and manufacturing technology. Designed, developed and manufactured in the UK,
the Integra Ri3 dms builds on Crompton Instruments' long established reputation for
metering product quality.

The product features a DIN-rail enclosure, backlit LCD display and user programmable CT
ratios, all accessible via an intuitive user interface, Integra Ri3 dms measures 17 electrical
parameters including total harmonic distortion (THD) mesurement up to the 31st harmonic.
