GH-6066A Low Concentration Smoke Multi functional Sampling Tube (Heating Type)

Execution standards

GB/T16157-1996 "Determination of particulate matter in solid pollution source exhaust and sampling methods for gaseous pollutants"

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

purpose

Used for measuring particulate matter with a fixed pollution source concentration below 50mg/m ³, with a low detection limit of 1mg/m ³. The S-shaped pitot tube, platinum resistor, heating element, and sampling tube are designed in an integrated manner. The filter membrane holder of the sampling tube has a heating function to keep the filter membrane working at the set temperature and can adapt to high humidity, low temperature, and other working conditions; The filter membrane bracket components (filter membrane, bracket, front bend tube, sampling nozzle) can be weighed as a whole to minimize the possibility of filter membrane mass and particle loss.

Performance characteristics

The overall weighing of the filter membrane bracket component reduces the possibility of filter membrane mass and particle loss, resulting in small sampling errors

The high-efficiency filter membrane heating device made of new materials ensures the smooth sampling process and accurate sampling results for high humidity, low concentration, and low temperature conditions

◆ Use a filter membrane with a diameter of Φ 47mm to collect particulate matter

The heating temperature can be set and automatically adjusted, using a 24V DC power supply for heating

The sampling nozzle and bend tube are made of titanium as the processing material, which has stable performance, corrosion resistance, and low self loss

The filter membrane components have been manufactured in the laboratory and can be directly sampled on-site, making it convenient and fast

◆ Compact structure, suitable for measuring hole diameter of 80mm specified in standard GB/T16157

◆ Suitable for pollution sources with particle concentration below 50mg/m ³

Low detection limit, with a low detection limit of 1mg/m ³

◆ Customize the length of the sampling tube according to customer requirements
