  • Size/Dimensions (working volume):
  • 260 cm wide x 260 cm deep x 220 cm height
  • Temperature Range: -50°C to +120°C
  • Controlled Relative Humidity: between 10% and 95%, over the temperature range of +10°C to +95°C
  • Tolerance: +/- 0.7 K; +/-3% relative humidity (3-D space and time-wise)
  • Temperature Cooling/Heating Rate: 2 K/min

Shaker System

  • The shaker system interfaces with the chamber, and is utilized for both vertical and lateral vibration testing profiles. It can also be use separately from the chamber.
  • Force rating: 29kN (6500 lbs)
  • Displacement Peak-to-Peak: 50.8mm (2 inches) maximum
  • Velocity: 1.8 m/s (71 inches/sec)
  • Acceleration: 735 m/sec2 (75 g)
  • Low Noise Operation Mode: during low noise operation mode the noise level is <NR35
  • according to ISO 1996. This mode is useful for squeak and rattle testing of automotive parts.
