| TEMPERATURE & HUMIDITY CHAMBER |
| BENCH-TOP(Model:th-1ST-A;TH-2ST-A) |
| Humidity controllable Range (at room Temp.20℃ |
| |
| *It can separately test high temperatures, low |
| Temperatures and costant temperature and himidity. |
| *All programmed instructions are microprocessor |
| -controlled, with PID and automatic calculation |
| To ensure precise and stable temperature and |
| Humidity control. |
| *Heating, cooling, humiditying and dehumiditying |
| Functions are all sleperate, for increased effici- |
| Ency, lower energy and maintenance costs and |
| Longer machine life. |
| *In the case of a thermostat breakdown, a war- |
| Ning light switches on and temperature setting |
| Is changed to standard. |
| *Heat is evenly distributed throughout the testing |
| Chamber to ensure a uniform testing temperature. |
