ProUmid

Moisture equilibration of powders, granules or pellets at controlled relative humidity.

Dynamic Flow Method
A defined gas flow with controlled RH is passed through a powder bed. The formation of lumps or air channels is inhibited by continuous agitation.

Fully Automated
Completion of conditioning process is automatically determined by the instrument based on the continuous measurement of RH at the inlet and outlet flow.

Moisture Content
Water uptake of the powder is calculated by a software algorithm from the gas flow rate, the temperature and RH readings.

Humidity Control
The powder conditioner is connected to a MHG32 humidity generator or comparable equipment that provides a humidity controlled gas flow.


 

The sorption test instruments of the SPS series are integrated systems for automatic gravimetric determination of the water vapour sorption and desorption of multiple samples in a test atmosphere with controlled temperature and humidity.

Unique features of the SPS systems:

•  Simultaneous measurement of up to 23 samples
•  High accuracy and reproducibility with sample quantities from 3 mg up to 220 g
•  Excellent surface-to-volume ratio of the samples for optimised sorption kinetics
•  Drift compensation of the balance with internal reference
•  Parallel samples for separate analyses can be taken while measurement is running
•  The SPS instruments are easy to operate and enable reliable measurements with very high accuracy.

The Vsorp is an easy to operate, high sample throughput instrument for routine measurements in research, development and quality assurance. Combining our longstanding experience in the construction of measurement devices with state-of-the-art manufacturing, the Vsorp covers the requirements of an advanced multisample instrument at a reasonable price.

The modular humidity generator MHG32 was designed to control humidity in challenging instrument environments. The generation and control of relative humidity directly at the analysis equipment enables a fast and accurate response even at very low flow rates.

The MHG32 provides a maximum flow rate of 500 ml/min and is suitable for chamber volumes from approx. 20 ml up to 25 l. The modular setup and the broad temperature and humidity range make it a perfect match for the most diverse target systems.

The extremely powerful MHG100 was designed for use in applications with high flow rates as they are required in open systems or for large chamber volumes. Humidity regulation in a closed loop and at controlled temperature allows for accurate adjustment of relative humidity levels even in challenging settings.

The MHG100 provides a maximum flow rate of 15 l/min which is suitable for chamber volumes of up to 300 litres.

The modular setup with symmetrical gas supply in two lines and the broad temperature and humidity range make the MHG100 a perfect match for the most diverse target systems.
