Analog Panel Monitors

Acrylic Window

Glass Window

Observe rapidly changing electrical values in equipment such as motors and generators with an analog display that shows the magnitude and rate of change more easily than a digital display.

Monitors with electromagnetic interference (EMI) resistance are shielded to prevent interference and maintain accuracy when mounted on a magnetic panel.

Panel Monitors

For 1/8 DIN Panel Cutout

For 3/64 DIN Panel Cutout

See how much electricity motors, generators, and other electrical equipment use. The high-visibility digital screen displays electrical measurements with more accuracy than an analog panel monitor.

Monitors with a scaling range can be adjusted to compensate for measurements that are outside the monitor's set measuring range.
