Medical mask dead cavity tester
1, Overview:
Sq2626-a medical mask dead cavity tester is designed and
manufactured according to relevant standards. The instrument is
specially used to detect the dead cavity of medical mask.
Sq2626-a medical mask dead chamber tester is composed of
intelligent controller, airflow mechanism, printer, carbon dioxide
analyzer, respiratory simulator, 5% carbon dioxide gas source, etc.
The intelligent controller is composed of PLC, ad module, LCD,
emergency stop, power supply, timing system and so on
The screen adopts all Chinese windows display, touch control for
options, operation, setting, without training, you can operate
according to the prompts.
