Sirius Multigas Detector provides users outstanding multifunctional capabilities
by integrating a high-performance PID (Photoionization Detector) sensor into
a 4-gas detector. Users are able to simultaneously monitor for volatile organic
compounds (VOCs) with low vapor pressures while measuring for combustible, toxic
and oxygen-deficient atmospheres within one reliable, easy-to-use, durable unit.

For years, fire departments, law enforcement
agents, HazMat teams, and now more than ever First Responders, have been concerned
about detecting and identifying hazardous compounds in emergency situations.
Several techniques and technologies are used such as PIDs, capable of effectively
detecting and monitoring several hundred, if not thousands, of hazardous substances
for maximum benefits and safety to users. Ideal for use in a wide variety of
applications, including Homeland Security, First Responder, Fire Service, Hazmat
Response, Petrochemical, Chemical, Aviation, Marine, Utilities and General Industry.
Units range from $2,450 to $5,085. Ordering
PID and four gases in one instrument allows for detection
of hundreds of chemicals. The Sirius Multigas Detector provides
users outstanding multifunctional capabilities by integrating
a high-performance PID (Photoionization Detector) sensor
into a 4-gas detector. Users are able to simultaneously monitor
for volatile organic compounds (VOCs) with low vapor pressures
while measuring for combustible, toxic and oxygen-deficient
atmospheres within one reliable, easy-to-use, durable unit. Following
are some of the common substances that a PID can detect and
monitor: Benzene, Toluene, Vinyl chloride, Hexane, Ammonia,
Isobutylene, Jet A fuel, Styrene, Allyl alcohol, Mercaptans,
Trichloroethylene, Perchloroethylene, Propylene oxide, Phosphine.
PID Performance MSA’s own proprietary PID sensor design
(patent-pending) provides users with excellent PID performance
including humidity resistance, stable zero readings, and fast
response and clear times to enable users to get their jobs
done dependably. User-Friendly Software Easy-to-use software
allows users to focus on their tasks at hand! Reading measurements
for combustible gas, CO, H2S, O2 and VOCs with their character
names are clearly and simultaneously exhibited on the display.
A noticeably visible battery life indicator is also continuously
displayed to inform users of the remaining run time on the
unit. When measuring for general VOCs with isobutylene as the
reference gas, users can easily read the chemical name “ isobutyl” in
a designated dashboard on the display.
a known gas is present, it is easy to obtain a direct reading
measurement for that known gas by using an automatically calculated
corresponding response factor to isobutylene, which is preprogrammed
into the Sirius unit. Eight alpha characters clearly spell
out the VOC gas of choice selected by the user in the dashboard
display area. The Sirius unit automatically calculates response
factors by easily scrolling through a “ favorite-five” list
or by selecting a gas from a 100 gas pre-programmed list. Customized
chemical names and corresponding response factors can also
be easily added to the list. A user-selectable option to enable
ppb VOC readings below 10 ppm is also available, giving users
added flexibility for their VOC monitoring needs.
Proprietary PID Sensor reduces maintenance time and cost!
PID lamp access is made easy with the Sirius unit. When users
need to change or clean a PID lamp, it is so simple with
a twist of the lamp holder located conveniently on the front
of the instrument. Color-coded lamp eV ratings for easy lamp
discrimination also adds to the ease of changing lamps. Two
lamps are available; a red color labeled 9.8 eV lamp for
more discrimination and a green color labeled 10.6 eV lamp
used for most VOCs. A tamperproof version of the PID lamp
cover is also available. Any future maintenance of the ionization
chamber is also simple and can be done easily at the customer’s
location. An easy-to-access ionization chamber is simply
removed, disposed of and replaced.
This design combines two instruments
into one! The Sirius unit can be used with or without the PID sensor
mode. When only a 4-gas detector is needed, users can select to
turn off VOC readings, allowing users to have a built in capability
for confined space monitoring. If a PID sensor is in the future
for a customer, but not presently needed, a PID sensor can be simply
added to the unit at a later time.
Sirius Multigas Detector provides loud,
attention-grabbing alarms to clearly warn users of a
hazardous situation. A piercing alarm horn, resonating through
a specially designed horn chamber, is designed into the Sirius
unit to give users an audible warning in the event of an alarm
condition. Multidirectional bright LED lights give users visible
warning of alarm conditions that can be easily seen from any
direction the Sirius unit is facing. A “Safe
LED” light gives users confidence the unit is actively detecting gas by
flashing every 15 seconds.
Lithium-ion and alkaline battery packs keep instruments running
24 hours a day, 7 days a week! A unique, user-friendly design
for the alkaline battery pack provides users with a simple-toaccess,
slotted thumb screw to easily swap out batteries in the field.
An attached lid to the alkaline pack prevents users from losing
any parts while at a work site. A lithium ion battery pack
with optional vehicle charger is easily interchangeable with
the alkaline battery pack. Charging the lithium ion battery
pack can be done in the unit or Barseparate from the detector.
This interchangeable design and flexible re-charging scheme
allows for quick battery turn to keep users continually charged
and ready to take action.Easy
calibration and compatibility with MSA’s Total Instrument
Manager increase user safety by easily ensuring proper sensor
performance! One-button calibration makes calibration simple
for any user. Intelligent software frees users from complicated
calibration adjustments. The Sirius Multigas Detector is also
compatible with MSA’s Total Instrument Manager for automated
calibration and record keeping.
storage kit allows users to be confident they have what it
takes to ensure their Sirius unit is working properly and
will be ready to go! When emergency response conditions may
arise, the long term storage kit provides all the tools necessary
to keep the Sirius Multigas Detector running if the unit
has not been frequently used. The long term kit includes
a premium storage case, Sirus Multigas Detector with combustible,
H2S, CO, O2 and PID sensors, calibration cylinders, spare
sensors with hermetically-sealed O2 sensor to last two years,
spare PID lamp, lamp cleaning kit, extra PID ionization chamber,
both alkaline and rechargeable lithium ion battery packs,
and vehicle charger. A pictorial of how to quick start the
unit is also attached to the lid of the case to help users
easily understand how to ensure the safe starting operation
of the unit if they have not recently used the Sirius Multigas
The Sirius Multigas Detector unit with PID Sensor gives users all they are looking
for in a reliable, easy-to-use, durable package to detect volatile organic compounds,
while measuring for combustible, toxic and oxygen deficient atmospheres. This
