2.5 SAMPLING
In normal operation the Impact is worn on the belt, with its
harness, or held by hand. Once turned on the Impact monitors
the atmosphere continuously, which reaches the sensors by
diffusing through the vents of the grille cover or by being pulled
through by the internal pump (if fitted). For non-pump
instruments normal air movements are sufficient to carry the
sample to the sensors, and the sensors react immediately to
changes in concentrations of the gases being measured in the
atmosphere immediately surrounding the detector. Depending
on your application and the options fitted to the instrument the
environment can be sampled remotely in a variety of ways, as
summarised below:
