The MH3090 multifunctional sampling tube (21st generation) is a newly developed multifunctional sampling tube by our company that can measure working conditions separately, and can also be equipped with integrated sampling nozzles, filter cartridge sampling nozzles, or oil fume sampling nozzles. When sampling smoke and dust, the filter membrane or filter cartridge can be heated, suitable for high humidity and low dust conditions.

Execution standards

• HJ/T 48-1999 Technical Conditions for Smoke and Dust Samplers
• HJ 836-2017 "Determination of Low Concentration Particulate Matter in Fixed Source Waste Gas by Weight Method"
• HJ 1077-2019 "Determination of fixed source exhaust gas, oil fume and oil mist - Infrared spectrophotometric method"
• GB 18483-2001 "Emission Standards for Cooking Fumes in the Catering Industry"
• GB/T 16157-1996 "Determination of particulate matter and sampling methods for gaseous pollutants in exhaust from stationary sources"

Main features

• Three in one filter membrane, filter cartridge, and oil fume sampling function, light equipment for outdoor sampling;
• Simultaneous measurement of working conditions, dynamic pressure, static pressure, and automatic zeroing during sampling;
• Built in high-precision gyroscope, deflection out of tolerance reminder, intelligent sampling for more accurate results;
• The portable design of the working condition box allows for easy insertion and use, reliable connection, and can be paired with different sampling tubes;
• The handheld device and sampling tube support wired or wireless connections. During the sampling process, the handheld device can be taken out for observation without the need to keep watch over the host.
