Climate chambers
We offer large sample storage and testing chambers with climatic conditions controlled at extremely high precision, e.g.:
- Testing and storage chamber with 90±3 %RH and 20±0.3°C (max. 20 m2)
- Testing and storage chamber with 70±3 %RH and 20±0.3°C (max. 20 m2)
- Testing and storage chamber with 57±3 %RH and 20±0.3°C (max. 20 m2)
- Testing and storage chamber with 35±3 %RH and 20±0.3°C (max. 20 m2)
- Carbonation chambers with adjustable CO2 concentration and RH
- Wind tunnel with a wind speed of 7.5±0.5 m/s and adjustable temperature/RH (e.g. for plastic shrinkage cracking tests at 33±1°C and 35±5% RH)

Concrete slabs prepared for testing
In addition to climatic chambers with fixed conditions, we offer chambers where climate can be adjusted for the special needs of your tests, e.g.:
- Storage chamber, 20-60°C, up to 90% RH (max. 10 m2)
- Storage chamber down to -25°C (max. 15 m2)
- Different sample storage cabinets/desiccators with adjustable temperature and RH (filled with air or nitrogen)
Please contact us for further information on the availability and temperature/RH range.
