Product Introduction: The TQC-3 Universal Individual Air Sampler is specifically developed for the "GBZ/T 192 Workplace Air Dust Determination" and "GBZ/T 160 Workplace Air Toxic Substance Determination" standards. It is used for short-term, long-term, or individual sampling, and is used for membrane sampling, liquid absorption, or adsorption tube sampling with flow rates below 3L/min. However, it is not suitable for long-term sampling with low flow rates below 200ml/min. Main purpose: Individual or long-term dust sampling (1-3L/min).
