儀器簡介：
YL-2231可程式高低溫試驗機
簡介：本產品采用高微電腦觸控式控制器，搭配高穩定度的白金測溫抵抗體，配合風速循環系統，以達到均勻、準確、穩定的溫度控制。可作高溫、低溫不同的環境試驗。
YL-2231 High and Low Temperature Tester
High and low temperature tester uses high-texture appearance, arc shape body, and matte fringe processing of surface, planar non-reactive handles, easy operation, safe and reliable.
>>>Rectangular complex layers of glass view window can be used for observation specimen when doing testing. With anti-sweat heater unit of the window can prevent water vapor condensing water droplets, and high-brightness PL fluorescent lamp keeps box lighting.
>>> Testing hole can connect external test power line and signal line and adjust specimen tray by up and down.
>>> Airtight and closed double-isolated door can isolate effectively the internal temperature leakage.
>>> Compressor circulation system adopts French “Taikang” Brand, it is more effective to remove condenser tube and capillary lubricants, and full ranges of series adopt environmental refrigerants (R-23, R-404).
>>> Controller adopts imported LCD display screen, can display simultaneously testing values, setting values and time.
>>> Controller has multi-stage program editing, temperature and humidity can make QUICK or SLOP control.
>>> Built-in mobile pulley is convenient to move and display, and with a strong poisoning screw to fix position.
YL-2236 Programmable Temperature & Humidity Tester
Purpose：
Programmable constant temperature & humidity test is designed for testing the capability of heat-endurance, cold-endurance, dryness-endurance, and humidity-endurance. It is suitable for the industries of electron, electrical equipment, vehicle, metal, chemistry, building materials, luggage, adhesion tape, printing, packaging, etc.
YL-2280 Thermal Shock Tester
This Tester is mainly test materials resistance in extremely high temperature or extremely low temperature. This situation is similar to non-continuously being low temperature or high temperature; thermal shock tester can make various products accomplish test in shortest time. Chemical change or physical injury made by heat shock is caused by thermal expansion and contraction change or other physical nature change; use TST system to achieve entire trust for various products. Effect of heat shock is including finished products cracked or broken layer, and electrochemical change caused by replacement. All-digital automatic control of TST system makes you easy and handy operation.
