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.

Provides users outstanding multifunctional capabilities by integrating a high-performance PID (photoionization detector) sensor into a four-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.
