Hitachi High-Technologies GLOBAL

  1. Junction temperature control in each individual LED element is possible
  2. Can perform measurement of changes of each individual LED element over time with regard to electrical properties and amount of light.
  3. Long hours of passing of electric current and endurance testing can be done and life assessment of each element can be performed
  4. Has a temperature coefficient measurement function (Can make connection with thermostatic bath)
  5. The equipment is composed of one block (8 ch) each, and can be expanded per block in the future (maximum 128 channels)
