The Salwico GD SS HART range of gas detectors is used to monitor areas where am-
mable, oxygen deciency and toxic gases may pose a hazard environment. The Salwico
GD SS HART uses a number of sensor technologies including catalytic bead and elec-
trochemical cell. The stainless steel enclosure makes it suitable for harsh environments.
Salwico GD SS HART has a long list of user friendly features:
• One hand operation for sensor replacement
• Clear multi-function backlit display
• 4-20 mA signal output
• 3 Switch relays
• HART

The Salwico GD TRUE IR gas detector is a point detector for gas concentration moni-
toring potentially hazardous environment. The Salwico GD TRUE IR is based on infrared
absorption. Solid state design improves reliability, long-term stability and accuracy in
continuous measurement of gas concentrations in ambient air. Compared with catalytic
sensors the Salwico GD TRUE IR has the following advantages:• Proven high reliability
and long term stability esults in low test frequency and no calibration
cost • Automatic self test • Failure will not give gas alarm • Presence of oxygen is not
required during equipment life time • Immunity to poisoning from H2S, silicone and
other agents • No saturation effects from high gas concentrations • The gas ow rate
has no inuence on accuracy • Several different mounting possibilities
Special junction boxes or duct mounting brackets are available upon request.
