HVAC line - relative humidity/temperature transmitters
HygroMaxx
High performance measuring instrument with large LCDisplay for air relative humidity and
temperature. For installations in rooms or ducts. The digital capacitive humidity measurement cell
in conjunction with a newly developed sensor technology, enable this device to be used in various
applications for measuring climatic parameters. Operation is effected via 3 keys and an intuitive
menu. The HygroMaxx transmits 2 analogue outputs for relative humidity and temperature.
These can be scaled as required. Optimal integration into a control system can therefore be
achieved. The HygroMaxx is available in different versions for room and duct measurement.

HygroMaxx
Measurement instrument HygroMaxx:
Humidity/temperature transmitter for HVAC and process controls with local
LCDisplay.
The HygroMaxx product series have been developed following the newest
technology in monitoring and controlling in the HVAC sector. These products
represent an ideal combination of performance and price. The new sensor
technology, the configuration possibilities and the robust design set a new
standard in the HVAC field.
Thanks to the new design conception, these instruments are easy for
installation and maintenance. Integrated menu functions facilitate the startup, service resp. the RH adjustment with the Novasina SAL-SC humidity
standards. Furthermore this product can be easily customised and adapted
to specific needs (OEM versions).
Applications:
HVAC process-control and -monitoring
Paper and textile manufacturing and handling
Controls and monitoring systems in labs and metrology rooms
Monitoring of industrial combustion processes
Storage and archive monitoring in museums and libraries
Storage systems, cooling rooms in the food & pharma industry
