Why we offer new chamber NO DOOR α solve many issues current traditional testing chamber?
There are many testing chambers available in the market. However, the majority of them has a lot of problems. Some of them include uncontrollable temperature, visual problems of the testing area, unstable testing environment among others. All of these will lead to inefficient and unreliable results.
Pros and Cons of Traditional Testing Chambers
Giant size walk-in chamber
Pros - Large testing area, Not expensive compared to giant size walk-in chamber
Cons - Very expensive, Hard to manage temperature, stressful working environment
Large size walk-in chamber
Pros - Large testing area, not expensive compared to giant size walk-in chamber
Cons - Expensive, unstable temperature, stressful working environment
Medium size chamber with two holes
Pros - They can touch the specimen, less stressful working environment
Cons - Hard to operate smoothly, hard to see if screen get foggy, expensive
Small size chamber
Pros - Easy to manage, unexpensive
Cons - Too small, limited testing capabilities, you can not touch the specimen while testing
No Door α Capabilities
No Door α is the latest innovation in the testing chamber industry. It is boasting a no door chamber that controls humidity and temperature. It features an air curtain that creates straight, soft and stretched air door. You can operate your test specimen without affecting the testing environment. It is equipped with two layers of honeycomb air supply to softly move air in one direction. The gentle air stream prevents contamination from the outside and creates no turbulence even if it's open.
Features
Small observation of test specimen in every angle because it has no door.
Completely open - solving visual problems
Manipulate specimen freely with precision
Merits
No air stream in the testing chamber
High reliability
Anti Static
Operability
Workability
Uses of No Door α in various industries
PC with printer
Screen Test, Realiability test
Printer
paper and printing test
Smartphone
Touch screen test, USB testing
Tablet
Reliability of test display
Adhesive tape
Peeling test, adhasive strength test
Features
- OPERATIONS AT WILL
- Operations can be done directly by connecting wires or putting hand inside without feeling the stress of temperature & humidity.
- UPGRADATION OF TESTING EFFICIENCY
- Testing samples can be put in or take out freely without distrubing temperature & humidity inside the chamber which usually occurs during operating & closeing of the door.
- WIDE TEMPERATURE RANGE
- In doorless condition: -20℃～+80℃, 30%RH ～80%RH
Temperature & Humidity Range
Advantages
① To manipulate your EUT precisely for operation/image check with Power-on
② To reduce Phisical Stress against Temperature and Humidity
③ To reduce Footprint & Initial Cost
