The HZSP-II Gas Chromatograph (Touch Screen) is a laboratory-grade gas chromatograph developed by Hertz, featuring a 7-inch color touch screen and a professional chromatography UI interface. The display intuitively presents the inlet, column oven, and detector internal temperature values, individual detector readings, and running time. A one-key cooling function simplifies operation, making the instrument straightforward and easy to use.
The instrument is widely applied in scientific research and education, petroleum, chemical, biochemical, food safety, medical and health, environmental monitoring, judicial investigation, and other fields. It delivers high testing precision and excellent repeatability for dependable results.
