Performance Index |
|
Environment Requirements |
Environment temperature:+25℃;R.H.≤85% This two values measured under the condition of no test sample in the chamber |
|
temperature range: -70~+150℃ humidity range: 20~98%RH
|
Control Accuracy |
temperature resolution: 0.01℃ humidity resolution: 0.1%RH temperature deviation: ±1.5℃ 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℃→-70℃ ≤80 min |
Note: heat capacity of the 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; |

Structure Feature |
|
Chamber Structure |
internal material:304# stainless steel with 1.2 mm thick external material: 304# stainless steel with 1.0mm thick or ( cold-roll steel sheets with 1.2mm thick, optional) heat preservation material: polyurethane foam rubber with 100 mm thick controller cabinet and test chamber integral type |
Air Conditioning Channel |
inside air space, recirculating wind channel and stainless steel cycle fan, through the top window and air diffuser, the wind will out uniformly from the top, let the reconciled temperature from the harmonic room diffuses to the test area, which could reach the purpose of control temperature uniformly. |
Door of The Chamber |
1)single open door 2)anti-explosion 3)anti-condensation electric heating device 4)vacuum auto-defog transparent window 5)window floodlight |
Lead Test Hole |
Φ50mm,enclosed with relative temperature preservation and heat insulation parts ,the special seal soft plug. |
Observation Window |
designed in the door with 230*260mm transparent electric radiant heating film with cavity toughened glass(equipped with anti-condensation function) |
Control Panel |
