1、 TC-890C National Standard Intelligent Microcomputer BOD Tester Product Introduction:

Biochemical oxygen demand: the dissolved oxygen consumed by organic and inorganic substances in water under specified conditions through biological oxidation. The TC-890C national standard intelligent microcomputer BOD analyzer uses an electronic digital pressure sensor instead of mercury pressure difference method to measure biochemical oxygen demand. Combined with a digital display screen, it can display the change curve of BOD5 value, making the data more intuitive; And the use of mercury free method reduces the harm to experimental personnel; And the stirring system adopts ultra-thin high-performance non mechanical electromagnetic stirring, with stable stirring and long service life; It can be widely used in various industries such as laboratory testing, sewage treatment, colleges and universities, environmental monitoring, sewage treatment, as well as colleges and research institutions.
