NHA-501型废气分析仪(五气)用于测量机动车汽油发动机排放废气中的HC、CO、CO_2、O_2和NOx气体浓度,自动计算显示空燃比λ。可对发动机的燃烧性能及排放污染情况进行综合检测。该仪器采用国外先进技术及全套进口机芯、传感器等组装而成。具有自动调零、高亮度数码显示、自动进行数据线性化处理和气路阻塞时自动报警等先进功能。配备模拟量输出接口及RS-232C数字串行通信接口。具有使用方便、测量准确及工作可靠等优点。
The NHA-501 exhaust gas analyzer (five gas) is used to measure the gas concentrations of HC, CO, CO_2, O_2 and NOx in the exhaust gas of a gasoline engine of a motor vehicle and automatically calculates the air-fuel ratio λ. Combustion engine performance and emission pollution can be a comprehensive test. The instrument uses advanced foreign technology and a full set of imported movement, sensors and other assembly made. With automatic zero, high-brightness digital display, automatic data linearization processing and automatic obstruction when the gas circuit alarm and other advanced features. Equipped with analog output interface and RS-232C digital serial communication interface. Has the advantages of easy to use, accurate measurement and reliable work.
