Liebisch desk type devices feature a 300-liter test chamber volume and are capable of conducting condensation humidity tests both with and without corrosive gases (e.g., in accordance with DIN 50017 and DIN 50018). A range of optional features are available to meet specific customer needs.
These chambers are available in both automatic ventilated and non-ventilated versions. The automatic ventilation system allows ambient air to flow through the test chamber during ventilation cycles without requiring the user to open the lid, enhancing convenience and safety. The standard test chamber temperature range reaches up to 50°C, which can be extended up to 60°C with the optional EA (elevated temperature) upgrade.

- TS EN ISO 3231
