About the Eclipse Detector Head
The Eclipse Detector Head is a fixed mounted, continuous-monitoring detector head. All
user adjustable parameters may be adjusted non-intrusively by use of an optical switch
which is accessible through a window at the front face of the detector head.
The Eclipse displays the current gas reading on an LCD display which is visible through
the window in the cover (front face). It also provides a 4 - 20 mA signal which indicates
the target gas reading for use by a recording device, gas monitor controller, or
programmable controller.
