Neware High and Low Temperature Test Chamber Safety Care Battery Test
High Low Temperature Humidity Test Chamber
1 . Temperature humidity Test Chamber aims to test battery performance under high low temperature by simulating harsh climate condition .
2 . It’s widely applied on Electronics , Telecommunication , Automobile , Packaging , Aerospace , Electric products , etc .
3 . Different run program can be set according to different test process of battery performance . Then the battery tester and chamber will run automatic by setting. Reduce the human operation .
4 . The chambers build - in sensor will trigger an automatic alarm when it detects abormal conditions . The chamber will protect and shutdown , then send the alarm information to the assigned terminal .
5 . Independent development the temperature control module in the electronic control system by Neware . Improve the control accuracy of temperature .
6 . Neware environmental test chamber aims to test battery performance under temperature by simulating harsh climate conditions .
7 . It can analyze and evaluate whether the battery can meet the required international standard and provides a good reference in the product R&D stage . Whats more , its widely applied to Electronics , Telecommunication , Automobile , Packaging , Aerospace , Electric products , Pharmaceuticals industry , etc .
It is forbidden to
1 . Test or storage of samples of flammable , explosive and volatile substances
