The MH3090C blank sampling tube is suitable for collecting full sequence blank samples when sampling low concentration particulate matter in fixed pollution source exhaust gas.

Execution standards

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

Main features

• Can meet the synchronous collection of blank samples for measuring holes with a diameter of ≥ 80mm;
• Can be quickly assembled and disassembled with existing low concentration sampling tubes, allowing for full program blank sample collection while conducting normal sampling;
• Guided structure, easy and fast operation.
