Modular Humidity Generator MHG
Alongside temperature, the relative humidity of the environment plays a crucial role in the properties of materials and products (structure, stability, flowability). Our high-precision humidity generators enable you to create defined environmental conditions for reliable analyses and measurements.
-
MHG32
The MHG32 is a modular humidity generator specifically developed for applications in demanding instrument environments with small volumes, where rapid changes in relative humidity are required. By generating and controlling humidity directly at the target system, it enables fast and precise control behavior.

MHG100
The MHG100 is a modular humidity generator designed for precise control of relative humidity in larger measurement chambers and open systems with higher gas flow rates up to 15l/min.
- Advantages and Special Features
- Fast and accurate humidity control even at low flow rates
- Wide temperature and humidity range
- No condensation in supply lines
- Easy operation and control by an integrated process controller
- Possibility to connect and to parameterise all standard analogue temperature and humidity sensors
- High Versatility: can be connected to any kind of analytical systems
- 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
- Application Areas
- Controlled Humidity atmosphere in analytical equipment, e.g. TGA, DMA, TMA, NIR spectroscopy, XRD or SAXS
- Microscopy applications such as AFM, Raman Spectroscopy
- Neutron and Synchrotron Science, Heavy Water humidification
- Powder Rheology, powder equilibration, powder testing (stickiness, caking)
- Controlled humidity environment in gloveboxes and temperature chambers
- Common physicochemical analyses to be conducted under controlled relative humidity
- Replacement of salt solutions in desiccators
- Operation
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 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 using the optional RS232 or Ethernet interface for remote control, all major parameters are controlled by and reported to an external host system. This perfectly integrates the MHG into complex test scenarios. A clear and fully documented Modbus interface allows for straightforward integration into existing test systems.
- Humidity Generator Software
- The MHG software controls all humidity generator 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
