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.
Principle(s) of Operation
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.
