Biological Air Sampler TRBS-601is highly accurate and has a fast sampling rate. It has a sample selection amount setting that can be adjustable from 0.01 to 2.0 steers, with a measuring range of 10 to 6000 L. It comes with an LCD that shows the sampling quantity3.53CFM/min, time, and other parameters. It has a collection efficiency of95%. It is programmable and simple to operate. To reduce puffball superposition and animal culturing error, the sampling hole has many small holes.
