Stack dust and flue gas PRODUCTS IN THE WORLD

Laoying3012H-D Portable High Flow Rate and Low Concentrations Stack Dust Automatic Tester

Product overview

It applies pitot tube isokinetic sampling method to collect particulate matter in stationary source emission, applies filtering and weighting method to determine the quality and applies constant potential electrolysis method to determine the concentrations of harmful gases. It can be used to determine the stack dust (gas) emissions concentration, equivalent concentration, total amount and dust removal, desulfurization efficiency of variety of boilers and furnaces. It can also be used to measure stack dynamic pressure, static pressure, the pressure and temperature in front of flow meter, temperature of flue gas, humidity ratio, concentrations of O2, SO2, CO, NO, NO2, H2S, CO2, Isokinetic sucking velocity and so on.
It is widely used for environmental protection, testing company, Industrial And Mining Enterprises, hygiene, working place, safety inspection, military, scientific research, education and other departments.
