PROCESS MONITORS

OMM 335PM is a 4-digit Process Monitor.

The device is microprocessor based and is designed for good accuracy and ease of operation. The circular section of the body of the box with a diameter of 22 mm allows for its fast and easy installation in control and monitoring panels by simply drilling a round hole, rather than creating a rectangular cutout. Can be loop powered.
