JYQ-IV type airborne dust and bacteria sampler

The JYQ-IV airborne dust and bacteria sampler is an efficient porous inhalation dust and bacteria sampler.

It is designed based on the theory of constant velocity sampling, with direct sampling. The wind speed at the collection head is basically the same as that in the clean room, which can more accurately reflect the microbial concentration in the clean room.

During sampling, the air carrying dust bacteria passes through the micropores at high speed and is uniformly impacted on the surface of the agar in the culture dish;

These living microorganisms obtain uniform and sufficient nutrients on the agar surface, and during the cultivation process, they undergo rapid dynamic rehydration and high-speed growth, resulting in faster results.

1Usage environment

（1）Temperature:10--50℃

（2）relative humidity10--90﹪RH

（3）Atmospheric pressure:80-110kPa

(4) Maximum dust concentration: 100000000 particles/ m3@0.5 μ m or 0.2mg/m3

IIMain features and parameters

(1) The sampling head has countless micropores, which evenly distribute microorganisms on the agar surface, reduce dust and bacteria overlap, and lower microbial counting errors.

（2）Sampling traffic:100L/min。

（3）Sampling head flow rate:0.38m/s is basically the same as the wind speed in the clean room (constant velocity sampling).

（4）The sampling amount can be obtained from0.001-9.999m3 can be set arbitrarily.

（5）Use standard universal culture dishesΦ90*15

（6）power supplyDC16.8V， After being fully charged, it can work continuously for 7 hours.

（7）Overall dimensions:Φ120*325 。
