EPD sample pre-dilution device

The EPD is an easy to use pre-dilution system for highly concentrated odour samples. It has been developed to increase the measuring range at high odorant concentrations for olfactometers.

And, because it ensures that the odour concentration of the air is not too high, it also prevents self-contamination of the olfactometer.

The EPD is designed for use in olfactometry laboratories and gives the operator the opportunity to process odour samples with a concentration of up to 6 x 106 OUE/m3 with just one additional mixing process.

Because the dilution precedes the olfactometric measurement, virtually all known odour emissions from environmental protection and industrial markets can be olfactometrically measured using this device.

In addition, the EPD can be used for dynamic pre-dilution as described in the automotive standards ISO 12219-7 and BMW GS 97014-4.
