The DMT242SC2 is similar to DMT242SC, but connections are made easy. The sampling cell includes welded Swagelok connectors at both the inlet and outlet that fit directly to 1/4" tubing.
To fit 6 mm tubing to the connectors, you can use an adapter such as Swagelok Reducer SS-6M0-R-4 (not supplied by Vaisala).
DMT242SC2 is the suitable choice in, for example, plastics drying systems, where the measurement is made by tapping off the dryer system and bringing a small air stream to the sensor. The Swagelok connectors of DMT242SC2 easily connect to a cooling coil or tubing, providing the essential function of cooling the dry air to ambient temperature before it reaches the sensor.
