Performance Index |
||||
|
Environment requirement |
Environment temperature:+25℃;R.H.≤85% This two values measured under the condition of no test sample in the chamber |
|||
|
Temp.& humid range |
temperature range: -20～+150℃ humidity range: 20～98% RH (see as below)
|
|||
Control accuracy |
temperature resolution: 0.01℃ humidity resolution: 0.1%RH temperature deviation: ±1℃ humidity deviation: ±2%RH temperature uniformity: ≤2℃ humidity uniformity: ≤3%RH temperature fluctuation: ±0.5℃ humidity fluctuation: ± 2%RH |
|||
|
Heating/cooling rate |
+25℃→+150℃≤45 min +25℃→-20℃ ≤20 min |
|||
|
Note: heat capacity of steel ≤35kg/m3 ;when humidity time,no heat resource; |
||||
|
Note: performance index above is under the condition of environment temperature is +25℃, and R.H. is ≤85％,no test sample in the chamber; |
