Gas measuring instruments / detectors are devices for measuring the concentration of gas in the air. Also known as gas indicators, these devices can measure both flammable gas and toxic gas. Gas measuring instruments / detectors are available in 2 types: one type measures concentration continuously and the other type measures either short-term concentration or long-term accumulated concentration. The type that measures concentration continuously uses various instrument analyzers, and the type that measures accumulated concentration is equipped with gas detector tubes. The right type of gas measuring instrument / detector needs to be chosen according to the gas to be measured (flammable/toxic), concentration, purpose and so on. Measuring instruments are available in various types as well, such as a portable type that can be carried around and a mountable type that is installed continuously. Choose a suitable type according to the measuring method and period.
