Introduction of the Instrument
With the development of modern biology technology, the biologic safety problem has drawn great importance to vast scientific and technical workers in biology field. The laminar clean bench is one of essential and widely applied basic facility in the biology technology researching, but its biologic safety and validity face severe challenge for the instant state of its main part HEPA (high-efficiency purifier).

Presently, as to the laminar clean bench widely used in inland, the user has difficulty in judging at the safety and validity of the HEPA. So, there are overdue services and invalid usages generally or to some extents exist in national college, junior college schools, and scientific research laboratories of research and application fields such as biology pharmacy. So, the safety and validity problem of the biologic technology are rather severe! ZHICHENG ZHJH-C series of new type laminar clean bench tackles the user's problem of monitoring the HEPA status.

It can display the HEPA status of the laminar clean bench on LCD liquid crystal display screen full in Chinese, monitor the whole process, and design two functions of invalid acoustic-optic pre-warning and warning. Additionally, automatic functions like real-time check, LCD wind speed display in fixed quantity and set the open and close time of the sterilizing lamp of ultraviolet rays randomly. The application of these series of technologies provides an invigorative solution for the problems, which has puzzled the biology field for years of overdue service and invalid usage of HEPA. The first 101 pieces ZHJH-1209C new type laminar clean bench won the bid in the bid invitation of animal cold chain project in the Agriculture Department, Xin Jiang corps on Nov.18th, 2004.
