The humidity generators of the MHG series are designed for fast and accurate control of humidity in specimen chambers of analytical equipment and technical environments.

MHG Humidity Generators

Advantages and Special Features

Fast and accurate humidity control even at low flow rates
Broad temperature and humidity range
No condensation in supply lines
Easy operation and control due to an integrated process controller
Possibility to connect and to parameterise all commercial standard analogue temperature and humidity sensors
Algorithm for the correction of humidity levels in the case of thermally separated samples
High Versatility: can be connected to all kinds of analytical systems

Application Areas

Controlled Humidity atmosphere in X-ray diffractometry, TGA or DMA
Environment of control humidity in gloveboxes and temperature chambers
Common physicochemical analyses to be conducted under controlled relative humidity
Replacement of salt solutions in desiccators (slow and susceptible to external influences)
Replacement of sulphuric acid solutions (work-intensive and hazardous)

Operation of the MHG

For easy set-up of all necessary parameters, the modular humidity generator is equipped with an integrated process controller and graphical user interface

The values for temperature and humidity can be read off directly
Nominal values for humidity and flow can be entered directly
Complex humidity profiles with plateaus, ramps or different humidity levels can be programmed very easily
Customer-specific interface requirements can be fulfilled easily and quickly
When choosing remote control via the RS232 or Ethernet (optional) interface, all major parameters are controlled by and the measured values reported to an external host system, thus integrating the MHG perfectly into complex test scenarios
In the case of thermally separated samples on a heated or cooled sample plate, humidity levels can be corrected by means of an appropriate algorithm

MHG software

The MHG software controls all MHG parameters and can generate and store any number of humidity curves (methods)
With the “Multisample/Multimethod” option, every sample in a multi-sample analyser can be assigned its own method and data file with sample data, file name and storage path
Numerous trigger and synchronisation functions are available to operate the MHG in complete synchronicity
Data is provided in a format that is compatible with Excel® and the most common scientific data formats
