General Description - CPS LEAK-SEEKER GS40 Manual De Operación

GENERAL DESCRIPTION

The GS40 is a completely self contained combustible gas leak
detector designed to pinpoint gas leaks in the most demanding
applications. An efficient and sensitive gas sensor is combined
with solid state circuitry which provides an audible alarm that
increases in pitch as the concentration of the gas increases. A
visual indication is also provided as well as provisions for an
earphone for use in noisy environments.
The sensor has been extensively tested and averages a useful
life of five years in normal operation. The sensor is capable of
responding to a wide range of combustible gases and other
toxic contaminants. Response levels as low as 25 ppm are
possible.
A modern design, combined with an efficient heated Tin Oxide
sensor, allows long operating life from a battery pack of only 4
AA cells. This allows for a very portable, lightweight instrument
featuring an 18 inch—46 cm—flexible metal probe capable of
reaching the most difficult locations.
The operation of the GS40 is fully automatic; no manual
adjustment is needed to obtain the full benefits of its unique
sensitivity and stability. Simply turn the ON-OFF switch to either
its HI or LO sensitivity positions, wait a short period of time
while the instrument automatically warms up the sensor, and
balances itself to the surrounding atmosphere, and the GS40
will start its audible alarm at a slow ticking rate to signal that it is
ready to search for leaks. During the warm up time, a bright red
LED signals the state of the battery pack: fully illuminated if the
batteries are OK or dimly lit if the batteries need changing.
The sensor in the GS40 has a normal life of over 5 years. However,
if accidental damage to the sensor occurs by getting wet or
clogged, it can be easily replaced as indicated in the maintenance
section.
The GS40 is not intrinsically safe in Class 1, Division 1
atmospheres and should be turned on and off in areas where
no combustible gases are present.
