This high speed response and sensitivity Semiconductor
Sensor Probe also enables initial external leakage surveys to
be performed in the vicinity of property or pipelines enabling
distribution leaks to be quickly found.
The instrument monitors all gases continuously, providing
all round protection for users.
The First Responder CG is equipped with both audible and
visual alarms and Geiger indications on the EXT flammable
range.
The First Responder CG includes the following ranges:
• 0 to 4,500 ppm to 20 %LEL flammable EXT Range
(External Semiconductor Sensor)
• 0 to 100% LEL
• 0 to 100% Volume Gas
• 0 to 1000 ppm Carbon Monoxide
• 0 to 100 ppm Hydrogen Sulphide
• 0 to 25% Oxygen
The First Responder CG has a variety of user configurable
options. This handbook details the default configuration,
with possible options detailed in italic text.
The First Responder CG instrument and Semiconductor
