Low concentration smoke sampling tube

The MH3090/MH3090T low concentration smoke sampling tube is suitable for the determination of particulate matter with a concentration below 50mg/m3 in fixed pollution source exhaust gas. The sampling tube is replaced by a sampling head containing a filter membrane and a sampling head fixing device. The rear end of the filter membrane sampling head has a heating function to keep the filter membrane working at the set temperature, which can adapt to high humidity, low dust and other working conditions. The integrated sampling head can weigh the filter membrane, front bend tube, and filter membrane bracket as a whole, greatly reducing the possibility of filter membrane mass and particle loss.
