    3.2. Labels and Explanations When operating the testo ASET15-1, the user always is operating under certain risk factors as electricity, hot surfaces, and the aerosols which are processed by the dilution and conditioning system. Therefore the testo ASET15-1 includes several safety features. Nevertheless, some precautions still need to be taken to ensure safe and reliable operation.

  • Page 8: System Overview

    Dilution and Conditioning 4.1.1. Principle testo ASET15-1 Air Supply / Evaporation Tube is an accessory for the testo MD19 which is the Rotating Disk Diluter with external diluter head for performing the primary dilution as close as possible to the aerosol source.

  • Page 10: The System

    39 Heat sink The testo ASET15-1 is power supplied by one phase electricity. An internal pump feeds filtered air to the integrated testo MD19-3E, where raw gas is added and therewith primary dilution is carried out. The testo ASET15-1 Air Supply / Evaporation Tube with integrated testo MD19-3E...

    ASET15-1 and the testo MD19-3E. The pathways of dilution air, raw gas and diluted measuring gas are visible. No external dilution air is needed. Ambient air is drawn and filtered inside the case of the testo ASET15-1 and fed to the testo MD19-3E where it is needed to dilute some raw gas. The primarily diluted gas then returns to the testo ASET15-1.

    5.2.1. Quick Couplings at the front of testo ASET15-1 testo ASET15-1 is equipped with two quick coupling elements to connect the device to an excess gas offtake (male coupling 12)) and to the subsequent sensor(s) (female coupling 13)). One female excess gas coupling 22) is included in testo ASET15-1 delivery and one male measuring gas plug 23) is delivered with testo MD19-3E rotating disk diluter.
