According to the test requirements and test standards, the cold and thermal shock test chamber is divided into three boxes and two boxes, the difference is that the test method and internal structure are different. The three-box type is divided into cold storage chamber, heat storage chamber and test chamber, and the product is placed in the test chamber during the test. The two-box type is divided into high greenhouse and low greenhouse, which realizes the switch of high and low temperature through the motor driven basket movement, and the product is placed in the basket and moves with the basket.
Thermal shock test chamber features:
1. Perfect modeling upgrade, easy to operate panel interface.
2. Adopt the original imported color touch LCD Chinese/English microcomputer temperature controller.
3. Vertical three-box structure, automatic control of cycle process of high and low temperature box, adjustable stay and conversion time, stainless steel inner tank, multi-form recording.
4. Equipped with multiple safety protection measures and devices.
5. Perfect protection alarm function: when there is short circuit, leakage, studio overtemperature; When the compressor overpressure, overload, oil pressure, water cut-off and other abnormal conditions, the screen immediately automatically displays the fault cause and provides troubleshooting methods, and when the input voltage is found to be unstable, it has an emergency shutdown device.
6. The movement time of cold and hot shock structure is within 10 seconds.
7. The cold and hot shock temperature recovery time is within 5 minutes, which can meet MTL,IEC,JIS,GJB and other specifications.
8. Expandable equipment: temperature recorder.
9.Ln2 rapid cooling control system.
10.RS-232 communication interface device, which can simultaneously monitor and record local area network with personal computer.
11. Function module: This equipment is divided into three parts: high temperature zone, low temperature zone and test zone. It adopts unique heat cutting structure and heat storage and cold storage effect, and adopts cold and hot air
12. Using the original daily microcomputer large LCD (320*240dots) Chinese and English display control system.
13. High program memory capacity, can be set to store 100 groups of programs, maximum cycles set 9999cycles, each time limit set 999Hrs59Mins.
14. With RS-232C communication interface device, it can be connected with the computer to control/edit/record and ten groups of dynamic links (TIMER SINGAL RELAY) 15). The function of 2 Zone or 3 Zone can be selected when performing hot and cold shock conditions.
15, the road switching mode into the test, do cold and thermal shock test.
16. With fully automatic, high-precision system, any part action, completely by P.L.C locking processing.
17. When the machine fails, it is equipped with automatic lines and warning signals. When the input voltage is found to be unstable, it has an emergency shutdown device.
