HJ836-2017 "Determination of Low Concentration Particulate Matter in Fixed Source Waste Gas by Weight Method"

2、 Product Overview

Suitable for low concentration sampling of flue dust, it needs to be used with an automatic smoke and dust testing instrument. Low concentration sampling of 1-50mg/m3 can also be used for<500mg/m3. The sampling bend tube is made of titanium alloy or 304 stainless steel material, which has stable performance and corrosion resistance. The sampling head includes: sampling nozzle quick connector, bent pipe, filter membrane, support net, and compressed aluminum foil. The sampling nozzle and sampling bent pipe are innovatively designed as separate parts, which can achieve quick installation of the same sampling bent pipe and sampling nozzles of different sizes.

3、 Performance characteristics

◆The sampling nozzle and sampling bend tube adopt a separate design to improve the interchangeability of the sampling bend tube. The two are assembled quickly and conveniently, with small size, light weight, and easy portability, making them particularly suitable for sampling on flue gas platforms.

◆Quick combination of sampling nozzles, using patented locking technology

◆The filter membrane is placed inside the sampling head and weighed as a whole, resulting in no loss of sample, small sampling error, and compact structure.

◆Suitable for measuring low concentrations of particulate matter from fixed pollution sources, with a minimum detection limit of 1mg/m3.

◆Using a filter membrane with a diameter of 47mm to collect particulate matter, in line with international standards.

◆Suitable for measuring hole diameter of 80mm as specified in standard GB/T16157.

◆The sampling nozzle and bend tube are made of titanium alloy or 304 stainless steel as processing materials, which have stable performance, corrosion resistance, light weight, and low self loss.
