4220 Chamber For Parametric Testing

  • Programmable Keyboard:
    Programmable keyboard allows temperature to be set, stepped (at user-defined increments), slewed (at user-defined rates) and cycled
  • Remote Operation:
    Chambers may be remotely controlled via IEEE bus or RS232C port
  • Flexible Tooling:
    Can be easily customized for testing needs
