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. Specifications GL 1122: Accuracy class - 5/0,5. The range of measured concentrations - 0,01·104 million-1 to 0,5·104 million-1. Nominal unit price of the least significant digit code - 0,01·104 million-1 volume fraction. Accuracy - ±(5+0,5 (Sk/S-1))%, where: Ck - the upper limit of the measuring range (104 million-1 volume); C - the measured concentration (104 million-1 volume). Changes in parameters of gas analyzers - not more than 0,5·±(5+0,5 (Sk/S-1)). Response time - less than 5 seconds. Wavelengths GL 1122: - Working - 3,4 microns; - Supporting - 3,9 microns. The presence of optical calibration (sensitivity control analyzer while purging gas path ambient air without the use of a control gas mixture). Having built a digital indicator device to output the results of analysis. Having an external analog recording instruments (scale - from 0 mV to 100 mV). Availability of digital printer device. Operating position - horizontal. Continuous operation - 8 hours. Dimensions - no more than 470×340×165 mm. Weight - 10 kg. Operating conditions GL 1122: The ambient air temperature - 10° C to 35° C. Relative humidity at 25° C - 80%. Atmospheric pressure - from 86,6 kPa to 106,7 kPa (650 mm hg to 800 mm hg). Voltage - 216,7 V to 242 V. Frequency - 50±1 Hz. Power consumption - no more than 60 V·A.
