Sampling Probes
In stack emission monitoring, sampling of stack gas is a very important and a commonly employed technique. In order to ensure a reliable analysis, it is essential that the sample gas is extracted free of ambient gas leaking into the system and at the same time the dew point of the sample must remain stable. A sampling probe fulfills this dual objective by acting as an interface between the stack and the analysis system.
A sampling probe comprises of a sampling nozzle, a sample transport pipe and in some cases a filter holder in addition to a Pitot tube and a stack temperature sensor.
Probe design is dictated by specific application. Probes are designed with different materials and may be heated or unheated.
We design and manufacture a variety of probe accessories to suit various applications and sampling conditions.
