N-2型空气NO_2无动力采样器

A Model N-2 Non-electric Sampler of NO_2 in Air

在N－1型采样器的基础上，使用复合挡风膜降低风速的影响，开发了N－2型空气NO2无动力采样器，它比N－1型采样器的精密度和准确度均有所提高．

A model N-2 air diffusing sampler of NO2 was developed.The complex films were used for decreasing the effect of different velocity of wind. Its precision and accuracy are higher than those of model N-1 one.
