The temperature impact test chamber is divided into two boxes and three boxes from the number of boxes and test methods. The technical indicators of the two box temperature impact test chamber are as follows:
1, temperature range: high temperature box: room temperature +10 ° C ~ 150 ° C
Cryogenic box: room temperature ~ -40 ° C (user-defined, limit low temperature -196 ° C)
2. Temperature fluctuation: ±1 °C
3, temperature error: ± 3 ° C
4, heating rate: from normal temperature ~ 150 ° C ≤ 25min (full range average)
5, cooling rate: from normal temperature ~ -40 ° C ≤ 30min (full range average)
6, the minimum temperature of pre-cooling: ≤ -45 ° C;
7, impact temperature: 150 ° C ~ -40 ° C
8, load: ≤ 30kg
9, sample area size: 250 × 250 × 250 (mm)
10, temperature recovery time: ≤ 5min
11, sample rack conversion time: ≤ 15s
12, power: 30KW 380V 50HZ three-phase five-wire system
13. Vertical two-box temperature impact test chamber impact test method: use the blue to move up and down between the high temperature and low temperature boxes to achieve the test requirements of thermal shock.
