System recommendations
TVOC 2 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 2 sensor will be
detected. Generally, the ambient environment in which TVOC 2 is located is readily accessed, but there are
applications listed below that require special consideration.
Gas sample systems
It is sometimes necessary to pump or draw a gas sample past the TVOC 2. 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 22
above.
TVOC 2 Flow Adaptor
Note: The Flow Adapters for TVOC and TVOC 2 are different parts.
Flow adapter fitting instructions
Replace the metal cap with the flow adapter re-using the plastic seal disk with its O-rings.
The flow adapter cap has M5 threaded holes for use with standard pipe fittings.
