Description
The air-conditioning meter for assessing the air quality of the room and for controlling and testing of RLT systems is characterized by an efficient measuring procedure.
The comfortable measuring device offers the right measuring technology for each application and different flow speeds, such as thermal probes, impeller or tailpipe measurement.
Sensor-dependant menus and selectable user profiles, e.g. for channel measurement or long-term measurement, offer simple operation. The new IAQ probe tests the ambient air quality by measuring the air’s CO2levels, humidity and temperature. In addition the Lux and comfort level probe can be used in order to assess the draft air. Clear analysis and archiving ensure for simple PC documentation. The new thermal probe incorporates temperature and humidity measurement. The special flow protocol documents the channel measurement professionally.
In addition, the connection of further temperature and humidity sensors is possible. Wireless, i.e. with data transmission via radio, the measured values of up to 3 temperature or humidity sensors can be displayed in the clearly arranged measuring instrument display.
