The constant temperature and humidity testing instrument is suitable for evaluating the wet heat aging test of various products or plastic components of tower cores, as well as the adaptability test of electrical and electronic products such as household appliances, instruments, meters, and components under high temperature, low temperature, wet heat, and alternating wet heat environmental conditions. It can be used for testing in various scientific research institutions and factory and mining center laboratories.
1Constant temperature and humidity testing instrumentAutomatic control system:
1Brand characteristics:
It can display the set parameters, time, and working status of the heater, and also has the functions of automatic test operation and PID parameter self-tuning. The setting of control parameters adopts a Chinese interface, and the automatic operation function of the refrigeration machine can be achieved by simply setting the temperature. The control system uses an intelligent control software system, which has the ability to automatically combine the working conditions of subsystems such as refrigeration and heating, ensuring high-precision control throughout the entire temperature range and achieving the goal of energy conservation and consumption reduction. A complete detection device can automatically display detailed faults and alarms, such as the controller automatically displaying the fault status when an abnormality occurs in the test chamber.
2. Human computer interface: 7-inch LCD color display screen, touch screen input without buttons.
3. User program capacity: 1-120 test programs (can be divided into 120 program groups), maximum 1-1200 steps (i.e. 1200 action steps), single step time of 99 hours and 59 minutes.
4. Deviation correction: To prevent parameter deviations caused by various factors, correction can make temperature and humidity values more accurate and standardized;
5. Temperature and humidity input: RT100 × 2 (dry bulb and wet bulb)/4~20mA built-in simultaneously;
IIConstant temperature and humidity testing instrumentMain configuration:
1. Heating device: using imported ceramic nickel chromium alloy heater, controlled by long-life contact solid-state relay;
2. Bottom of the box: Four swivel casters allow for free movement of the test box;
3. Observation window: Conductive film heated anti fog tempered glass;
4. Communication contactor: Zhejiang "Yaohua" brand;
5. One cable hole with a diameter of 50mm is used for testing (during the testing process, the specimen is tested for power on);
