Analytical Instrumentation & Environmental Monitoring


Gas detectors

May 2002 Analytical Instrumentation & Environmental Monitoring

International Sensor Technology (IST) which manufactures instrumentation to detect more than 150 different toxic and/or combustible gases, has awarded its representation to PREI Instrumentation.

These industrial instruments are used near ammonia refrigeration plants, liquid fuel and gas pipelines, water and sewage purification works, spray painting booths and paint factories, tanker loading facilities, smelters and furnaces and even in silos to detect any build-up of combustible or explosive gases.

The range of this equipment includes portable units, single and multipoint stationary systems, standalone sensor/transmitters and computerised gas monitoring systems. The range of sensors includes solid-state, catalytic bead, infrared, electrochemical and photoionisation detectors. In addition to sales, PREI Instrumentation offers spares, repairs, commissioning and installation. Vince Pinnock, with more than a decade of experience on this particular product, has been appointed product manager.
