THE OUTLINE OF FOREIGN BIO-ENVIRONMENTAL INSTRUMENTS AND THEIR DEVELOPING TENDENCY

To keep pace with the development of bio-environment engineering, we need all kinds of precise bio-environment monitoring instruments.This paper presents the current situation of bio-environmental instruments manufactured to 1980, including instruments measuring bio-environmetal factors and the characteristic and the specific property of organisms, typing the main technologyindex, giving the name of manufacturers and collecting data and recording system In addition, this paper also widely introduces the main properties of new type integrated sensors used in recent years and discusses the developing tendency of bioenvironmental instruments in the future.
