The Scientific Columbus Instruments JEM-2 Multimeter is a programmable Joule Electronic Meter from the Scientific Columbus JEM family, built for precise energy measurement and verification in lab and calibration workflows. Described as identical in design to the JEM-1, the JEM-2 provides multifunction energy measurements in a compact, solid-state multimeter-style instrument. Units are typically specified for 120 V AC at 60 Hz with a power draw of about 4 W. Discontinued by the manufacturer, the JEM-2 remains a historical standard in the Scientific Columbus lineup for energy measurement applications.
