1.6 Intended use
The Mixed Gas Sensor
KWL-VOC
measures the mixed gas concentration (VOC) in the
room. The Mixed Gas Sensor
KWL-VOC
can be connected to all KWL compact units
with the easyControls control system (Helios range) (up to max. 8 units).
Only use in normal room air. Aggressive gases can destroy the mixed gas sensor.
The mounting location affects the measurement accuracy. Proximity to windows or
doors should be avoided, because the measurement result will be distorted by drafts.
Any other use than the intended use is prohibited!
