590-300一氧化二氮被動采樣器
The Nitrous Oxide Passive Sampler samples nitrous oxide from 50 to 450 ppm (12.75 to 890 ppm-hours dose range) without the use of a pump. The sampler is user-filled with supplied sorbent to maintain low background and high recovery levels. The Nitrous Oxide Passive Sampler clips to a worker's clothing in the breathing zone and is suitable for 8-hour sampling at the ACGIH TLV of 50 ppm.
