SC311 Infrared Combustible Gas Sensors
Millennium II Series Sensors
The SC311 delivers the latest technology
advancements in infrared sensing of flammable
gases in a rugged package designed for the most
extreme industrial environments. Hydrocarbon
gas LEL detection is fast, reliable and highly
accurate with only periodic bump testing
recommended and a simple annual calibration
sequence. A full 5 year warranty is included with
a typical sensor life of 8–10 years.
Lowest power consumption available
Long range (+2,000 ft.) sensor separation
Industry leading 5 year sensor warranty
Field selectable gas curves available
Immune to poisoning - standard gases detected
include methane, propane, butane, and ethylene
ST3 Sensors shown with JB-MPD-A/S.
Very fast response and highly accurate
Designed to perform in the most extreme
industrial environments
ST3 XChem Toxic Gas Sensors
Millennium II Series Sensors
The ST3 XChem series of electrochemical
toxic gas sensors provide high specificity, fast
response, and long life. All ST3 sensors are part
of the universal Millennium II Gas Detection
platform and are compatible with the M21, M22,
and M2B transmitters. Our latest design employs
our “SimpleClick” sensor element design and
low power consumption.
Sensor end of life diagnostic
Plug and play design where the transmitter
automatically recognizes sensor configuration
Low power consumption increases uptime
Two year warranties available on most sensors
Field selectable gas ranges
Designed to perform in the most extreme
industrial environments
