Humidity and temperature test chamber / vertical

This system measures the light output
and forward voltage (Vf) of a LED under
HAST conditions (temperature:120?, relative humidity:85%),
and evaluates the light output degradation in a short period.
A combination of the HAST chamber and LED life evaluation system enables the highly accelerated life
evaluation of a LED.
?Test environment : temperature 120?, relative humidity 85%
?Number of test channels in total : up to 40 channels
?Number of test channels per measuring device (LBU) : 8 channels
?Number of measuring devices per HAST chamber : up to 5 units
?Constant current is supplied to each test channel.
?Range of constant current : 1mA - 500mA
?The forward voltage (Vf) can be measured along with the light output.
?The tendency of the light output degradation becomes clear within one week.
?The measurement data can be converted into a CSV format.
?The data sampling interval can be set by minutes.
