GL 1122 Gas analyzer

Also, this device can be called: GL1122, GL-1122.

GL 1122 analyzer - single-beam two-channel analyzer - designed to determine hydrocarbons in the exhaust gases during the research work on the final design of automotive spark-ignition engines. The operation of the device is a method of direct absorption of infrared radiation with the gas.

Scope of application: at SRI, in factories and other organizations associated with the development, manufacture, repair and adjustment of automotive spark-ignition engines.
