B-Guard Millennium LEL

Part Number: 67-8022-100

B-Guard Millennium LEL

Often hydrocarbons can be complex to detect with various cross sensitivity issues. The B-Guard Millennium LEL has simplified this issue by utilising a reliable single source dual wavelength Infra-Red beam.

GTA Millenium Series Infrared hydrocarbon detector is a single source dual wavelength instrument. The sensing and reference elements are self-compensating for optical integrity and other signal inhibitors. The industry standard 4-20mA analog output provides remote alarm, fault and calibration signals.

Applications

The GTA Millenium Series hydrocarbon detectors are designed to be used in the same applications where catalytic bead sensors have been applied.
