Overview
Programmable constant temperature and humidity testing machine NBC-150L-60 is mainly used to detect the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance and moisture resistance performance of various materials. The equipment adopts equilibrate Conditioning Control System (BTHC), which transmits the actual data in the test chamber to the controller through the induction system. The controller controls the SSR multi-stage intelligent output, and the equilibrate temperature and humidity system output power to ensure that the temperature and humidity in the test chamber are fully stable. It has energy-saving functions and reduces the power used to ensure long-term accurate and stable operation of the instrument.
Features
1. The product has beautiful appearance, reasonable structure, precise process, simple and convenient operation, stable and reliable performance.
2. The controller uses a large-scale color liquid crystal man-machine touch dialog LCD man-machine interface, which displays the operating status of the system in both Chinese and English, and supports RS232 computer interface remote control.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor, the components come from Japan, France, the United States, Italy and other origins, and the refrigerant adopts the American environmentally friendly refrigerant.
4. Reserve a 50mm diameter test hole on the left side of the test chamber.
5, with fully automatic, high precision system loop, using P.I.D automatic calculation control, the whole area temperature High Accuracy, High Stability.
6. Specially designed air circulation circulation system and sensing system to ensure Temperature Uniformity and avoid dead ends.
7. Adopt enlarged observation window, 4 layers of whole empty tempered Glass, wide field of vision.
8. The instrument is equipped with a comprehensive protection system, including power overload protection, leakage protection, over-temperature protection, etc., which automatically displays the fault point and stops when abnormal.
Principle
The equilibrate Conditioning control system (BTHC) is adopted, and the induction system transmits the actual data in the test chamber to the controller. The controller controls the SSR multi-stage intelligent output, and the output power of the equilibrate temperature and humidity system ensures that the temperature and humidity in the test chamber are fully stable and has energy-saving functions. The heating system adopts multi-stage heating pipes with PID modules to ensure temperature stability; the humidification system adopts a circular split humidifier to avoid low temperature freezing; the refrigeration system adopts imported Compressors and environmentally friendly refrigerants to realize forced refrigeration and thermostatic refrigeration segmented control; the air circulation system forces air supply through fans to ensure uniform temperature.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
1. Connect the power supply to ensure that the voltage meets the requirements.
2. Set the temperature and humidity program through the controller Linear dispersion.
3. Put the sample into the shelf and adjust the layer spacing.
4. Start the instrument and monitor the operating status.
5. After the test is completed, turn off the instrument and remove the sample.
Notice
• The use environment temperature should be maintained at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items cannot be placed within 60CM of the instrument.
• Power supply voltage variation allowable value is +/- 10%.
• The humidification system has water filtration and needs regular maintenance to avoid blockage.
• The instrument has a comprehensive protection system, which automatically stops when abnormal, and needs to deal with the fault in time.
