Multi-Component Gas Analyzers AVTOTEST - Accurate Emission Measurement Devices

Gas analysers multicomponent AUTOTEST (hereinafter - devices) are designed for simultaneous measurement of the volume fraction of carbon monoxide and dioxide, hydrocarbons, oxygen, nitrogen oxides in the exhaust gases, oil temperature, as well as the crankshaft speed of the engine of the car in operation, when released from production and after repair. The operating principle of the devices is based on selective absorption of infrared radiation by molecules of hydrocarbons, hydrocarbon dioxide and carbon monoxide in the analytical areas of the spectrum. Oxygen concentration is determined by electrochemical method. The engine shaft speed is measured by a high-voltage inductive sensor. The analytical signals of the measuring channels of the instruments are converted by a microprocessor according to a special algorithm and displayed in units of the measured values on the display. At the same time the measurement results can be printed out on the built-in printing device with indication of the instrument number.....
