The HZSP-II is a laboratory-grade gas chromatograph engineered specifically for the analysis of petroleum products and transformer oil. It features a 7-inch color touch screen with a professional chromatography UI interface, providing intuitive, real-time display of inlet, column oven, and detector internal temperatures, individual detector values, and running time. A one-key cooling function simplifies operation, making the instrument both straightforward and convenient to use.
The instrument is widely applied across scientific research and education, petroleum, chemical, biochemistry, food safety, medicine and health, environmental monitoring, and judicial investigation. With high testing precision and excellent repeatability, it delivers dependable performance for demanding laboratory environments.
