BSF-4 four air circuitair sampler

BSF-4 four air circuitair sampler

I. Overview

BSF-4Four channel atmospheric samplerIt is an instrument that samples one or two harmful gases in the air simultaneously. Suitable for environmental monitoring, health and epidemic prevention, occupational disease prevention, collection of harmful gases in industrial and mining areas, measurement of indoor environments, and collection of various harmful gases in the air by universities, teaching, research and other units. It is possible to collect samples of two different harmful gases simultaneously, as well as balanced samples and two samples at different times. It has the advantages of LCD display, menu operation, computer timing, small size, light weight, easy operation, accurate timing, high negative pressure for air extraction, needle valve mechanical adjustment for regulating valve, fine adjustment scale, and good stability. Since its launch on the market, it has been highly favored by users.
