The instrument features high measurement accuracy, high sensitivity and stable performance. It can respond quickly to changes in gas concentration and display real-time values. Some models support over-limit alarm, data recording and remote transmission functions, adapting to various harsh working conditions.

It is widely used in oilfields, petrochemical, chemical, metallurgical and other industries, especially suitable for scenarios where hydrogen sulfide leakage is likely to occur, such as oil fishing wells, oil production platforms and refining workshops. It is an indispensable testing equipment for safe production.
