ZR-3620A small flow gas sampler Introduction
ZR-3620A small flow gas sampler is an instrument for collecting gaseous samples from atmospheric and pollution source pipelines. Its working principle is to use sample pump to extract samples, and to achieve quantitative collection by steady flow measures and synchronous timing. The sampler can collect harmful gas samples such as TVOC in the air for short-term or long-term collection for environmental monitoring stations, health and epidemic prevention, labor protection, epidemic control centers, engineering quality indoor testing, scientific research units, colleges and universities, industrial and mining enterprises.
