Our portable and fixed gas analyzers measure hydrogen sulphide (H2S) in natural gas. H2S is a naturally occurring, but very toxic gas and needs to be removed before transmission to the national gas grids. The fixed analyzers are supplied with sample handling panels that are compact and specifically designed to cope with aggressive environments where natural gas is extracted and processed. The Liquid Drain variants GPR-7500 (A)IS LD for example can handle raw natural gas with entrained liquids without fear of damaging the sensor. The portable version the GPR-7100 is ideal for spot checking or verifying fixed installations. AII also supply a range of H2S scrubbers to remove the toxic H2S before venting the sample to atmosphere.
