Smart Link IV
|
Smart Link IV, it
is a portable CO/CH4 Gas Detector with built in
Wind Speed Anemometer, with visual indication
8x Hi Bright 4 x RED/ 4 x Green Led's for visual
indication of Gas and Wind Speed below 1m/s. LED's
are situated on all 4 sides of the unit so alarms
can be seen from any direction, the unit is totally
portable, it also has an Eye bolt hook to hook
in tunnels underground and on structures on surface.
