PC-422R8 & PC-422R8D- Unsaturated & Saturated HAST Chamber

PC-422R8 & PC-422R8D- Unsaturated & Saturated HAST Chamber

Used For:

  • Moisture resistance evaluation of new materials, and comparative test for development.
  • Preservation test of electronic components, etc., and identification of lot defects.
  • Pressure cooker tests /HAST are developed to accelerate the testing time of Temperature-Humidity-Bias (THB) testing which has typical conditions of 85 ⁰C and 85 % RH and usually takes 1000 hours of testing.
  • Unsaturated HAST Testing
