A-08740-BO Universal Opacity Monitor

Description

The basic Series A-08720-B0 Opacity Monitor includes an electronics unit with two breeching components: an LED light source unit and a receiver. Buttons marked Enter, Inc, Dec, and Reset are located on the front face below the display. These buttons permit interaction with the electronics. The standard vacuum fluorescent display shows all operation and alarm messages. For units equipped with auxiliary functions (described below), the additional necessary messages are also displayed. The opacity monitor stack units are easy to install because the wide-beam LED light source and narrow-view receiver do not require precise alignment. The opacity monitor is easy to calibrate and requires no routine maintenance other than occasionally cleaning the sight glass.
