System recommendations
TVOC is generally used to measure gas concentrations in the ambient atmosphere. The sensor is open to
the atmosphere and any gas that diffuses or moves under convection into the locality of the TVOC sensor
will be detected. Generally, the ambient environment in which TVOC is located is readily accessed, but there
are applications listed below that require special consideration.
Remote area monitoring
TVOC may be placed in a roof or other space that is hard to access but where the TVOC requires regular
bump tests. In this event, TVOC can be fitted with a Fixed calibration adaptor, Diagram 22. A flow adaptor is
also available for remote testing.

Gas sample systems
It is sometimes necessary to pump or draw a gas sample
past the TVOC. For this a “Flow Adaptor " can be
fitted. The flow adaptor has an inlet and an outlet port so that gas may be pushed or drawn across the
sensor. See diagram 2 above.
