INTRODUCTION
1.1 GENERAL DESCRIPTION
The GMI PS200 series combines quality, ruggedness and
advanced technology in a user friendly, portable gas detector.
It is compact, lightweight, water resistant, extremely robust
and is suitably certied to recognised International Standards.
The PS200 is designed for conned space monitoring, for
example, in sewers, underground piping, or within tanks and
other personal monitoring applications. With audible, visual
and vibrating alarms, it provides early warning of dangerous
gas levels.
The instrument is available as either a pumped or diffusion
model and is powered by an internal Li-ion (lithium ion)
rechargeable battery with an operating time of up to 80 hours
for non-pumped operation (20 hours for pumped operation).
Operating time is sensor dependent. Maximum recharge
time is 4 hours.
Operated via two push buttons, this instrument provides the
user with a simple to use, yet state-of-the-art, gas detector.
(Fig. 1-1).
The PS200 series features high visibility LED’s, a display that
changes colour from green to red when an alarm is present,
a sounder with a 90dB minimum output and a vibrating
alarm. Users can be condent that, should gas levels exceed
congured threshold limits or a sensor / ow / battery fault
exists, a clear and unmistakeable indication is evident.
