HJ 836-2017 "Determination of Low Concentration Particulate Matter in Fixed Source Waste Gas by Weight Method"

The DN18 sampling head is made with special technology and materials, and the sampling medium is built-in. The overall weight is less than 19mg! The sampling head is dried, sampled, and weighed as a whole, and the sampling medium is not in contact or damaged. The collected smoke and dust amount is closest to the true value. From now on, your workload will be greatly reduced and your data will be more accurate! Technical specifications of the sampling gun: Low concentration sampling of 5-50 mg/m3 can also be used for<500 mg/m3, and the total weight of the sampling head is ≤ 19mg.

Principle: Pitot tube parallel isokinetic sampling.

Marking circle:

How do you know which one? Each sampling head uses laser coding, and the uniqueness of the coding facilitates data management for you.

Low concentration sampling head:

We provide you with six types of sampling heads with diameters of Φ 4mm, Φ 5mm, Φ 6mm, Φ 8mm, Φ 10mm, and Φ 12mm, which fully adapt to the various flue flow velocity conditions you face.

Filter membrane mesh:

Don't underestimate this filter mesh with a diameter of 47mm. It has thousands of micropores on it, which not only effectively prevent the escape of glass fibers, but also have excellent breathability!

Sampler:

If equipped with Laoshan Electronic WJ-60B parallel fully automatic smoke and dust sampler and five combination sampling gun, it can easily achieve simultaneous monitoring and sampling of moisture content, smoke temperature, wind speed, smoke and dust!
