Flue Gas Parameter Monitoring


Sampling Probe

 Introduction The sampling probe obtains the sample gas from the flue or chimney, which is heated at high temperature to ensure that there is no liquid water in the sample gas. After the dust and impurities are filtered by the ceramic filter, the pure sample gas is output for measurement.

 Technical Characteristics The internal structure is made of stainless steel, which has strong corrosion resistance under high temperature. High temperature spray plastic shell, suitable for all kinds of outdoor work. Simple installation and convenient transportation. Support the whole calibration system.

Temperature Pressure Current Probe
