The GSP can supplement the CSD30 odour sampling device, and dilutes the sample directly at the sampling point.

Sample pre-dilution can be performed with nitrogen or synthetic air, whereby the pre-dilution ratio is fixed by the manufacturer (standard 1:10 with individual calibration data). The pre-dilution ratio can, however, be set to different exhaust air conditions on request by substituting the 1:10 screen with a sapphire screen accessible from the outside (e.g. dilution 1:5 or 1:20).

The sample pre-dilution system provides the sample air flow with a constant supply of nitrogen (N2) or synthetic air directly onto the tip of the sampling probe. The moist, warm sample is diluted immediately at the point of extraction with dry N2 or synthetic air. This means that when it cools down to the transportation and laboratory temperature, no condensation forms on the probe, in the tube or in the sample bag. As a result, no additional heating is necessary.

The GSP on-site sample pre-dilution device also has a built-in particle filter to protect against contamination, and a micro Prandtl tube, which can be used to monitor the sampling process.

GSP on-site sample pre-dilution device


The GSP on-site sample pre-dilution device is fully compliant with VDI 3880.


  • Sample pre-dilution at source
  • Avoids losses due to condensation
  • Includes a Prandtl tube for air speed monitoring
