： Scope of application :
( 如 SO 2 、 NO X 等 ) 采取溶液吸收法两路采集。 This instrument uses the solution absorption method to collect a variety of toxic and harmful gases ( such as SO 2 and NO X ) in the ambient atmosphere . It is suitable for monitoring and sampling at various levels of environmental monitoring stations, safety supervision, occupational health monitoring institutions, industrial and mining enterprises, scientific research institutes, education and other departments.
： Main features :
1. The sampling pump is an imported membrane pump, which runs smoothly, has low noise, and has a long life.
LCD 液晶显示，时间控制精确；可设置定时采样，延时采样和循环采样三种方式； 2 , the instrument uses a multi-function timing control module, LCD liquid crystal display, accurate time control; can set timing sampling, delayed sampling and cyclic sampling three ways;
3 , using lithium battery without memory effect, no need to discharge before charging;
99 h59min 内任意设置； 4 , the sampling time can be arbitrarily set within 99 h59min ;
。 5 , independent dual pump sampling .
