GB/T 14678-93 Low-temperature gas concentration meter

The FX-GCM-1D type is a low-temperature gas concentration meter is a concentration instrument that integrates sampling, concentration, desorption, sample injection, and cleaning. With a 7.0-inch intelligent color touch screen user interface, it can easily set or edit, store, and invoke methods, quickly start analysis, and make operation more convenient.

Application field:

Used for the determination of hydrogen sulfide, methyl mercaptan, methyl sulfide, and dimethyl disulfide in air quality. The relevant standards are GB/T 14678-93
 

Features
