CONTINUOUS PM10 & PM 2.5 MONITORING ANALYZER - ELECTRONICS - IN INDIA
Vasthi Instruments V.air – 9009, Real – Time Portable Beta Attenuation Mass Monitor, continuously measures the mass concentration of ambient particulate matter collected onto glass filter tape with time resolution of one-minute. The V.air – 9009 employs an in-line sampling geometry in which the attenuation of beta rays across filter media is measured and particulate matter is sampled simultaneously. This allows ambient sampling to occur for virtually 60 minutes each hour. It also allows for beta ray measurements to be made for virtually the entire hour thereby improving sensitivity and time resolution.
