AMETEK Process Instruments has added additional hazardous area certifications for its 993X series of wall mountable analysers.

These analysers are now ATEX and IECEx Zones 1 and 2, and ETL Class I Division 2 compliant for use in hazardous locations with ambient temperatures up to +60 deg C.

The 993X analysers use ultraviolet spectroscopy to measure hydrogen sulfide, carbonyl sulfide, and methyl mercaptan in natural gas and biomethane gas streams, as well as in sulfur removal and recovery operations.
