Temperature Humidity Vibration Test Chambers
Basic or Rapid Temperature Cycling
Labtek Temperature Humidity Vibration Test Chamber, it can be designed to combine with any your existing vibration system.
No matter your vibration system is vertical head expender, or with slip table, we can design different shape of combined chamber to meet your requirements.
Standard series capacity varies from 500L to 2000L. Ramp rate for standard series is 1°C/min, 3°C/min,5°C/min,10°C/min,15°C/min,
These chambers are designed for ease-of-use, reliability and performance and include many user-friendly features.
The chamber comes with touch screen controller and the latest in test chamber programming for ease of use. Users may choose to operate their controller on board of the chamber, or easily control on their computer through RS485 communications.
Removable floors
- Removable floors with circular opening to work with head expander or armature.
