Isokinetic stack gas sampler

Isokinetic samplers are used to sample dust and when the target pollutant is gaseous as well as partly fixed to the dust in the stack. Examples are the measurement of total dust, metals like Cd, As, Ni or Pb, dioxins, PAH.

Isokinetic sampling is obtained, when it is isoaxial and the mean sample flow velocity (vn) through the face of the inlet is equal to the gas flow velocity (s). Many European standards require -5% to +15% as limits for isokinetic sampling (e.g. EN 13284-1).

Old isokinetic technic uses manual adjustment of the isokinetic ratio. The measurement engineeer has to measure the velocity, to calculate the target value for isokinetic sampling and he has to adjust the valve every 5 or 15 minutes.

Genius5 is doing this job automatically. 100% of the sampling time. When sample flow velocity is too low, valve is opened automatically to increase the sample flow velocity. If too high, valve is closed step by step, until target is obtained.

Other comfortabel functions of Genius5 are the adjustment of probe and filter temperature, the indication for traversing and an automatic leak test, which expresses the result in l/h loss, as it is required by the standards.

All of the sampling data are stored on USB stick.Data can be evaluated with Ms Excel.

Genius5 is available as a split version or the compact version. Different sampling trains can be connected with standard plugs and connectors. It is an universal sampling system.
