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.
