Description
USED FOR FACE MASK AIR FLOW RESISTANCE AND DIFFERENTIAL PRESSURE TESTING TO CHECK BREATHABILITY AND CAN ALSO BE USED TO CHECK DIFFERENTIAL PRESSURE OF TEXTILE MATERIALS GAS EXCHANGER.
PRINCIPLE: THE OUTPUT OF THE AIR FLOW IS SET BY A GAS FLOW METER, THE AIR FLOW PASSES THROUGH A CERTAIN AREA OF THE TEST SAMPLE, THE CURRENT PRESSURE IS DETECTED BY A PRESSURE SENSOR, AND THE PRESSURE DIFFERENCE IS CALCULATED.
STANDARDS: YY0469-2011, YY0969-2013
FEATURES:
1. EQUIPPED WITH SPECIAL SAMPLE GRIP, EASY TO USE.
2. BUILT-IN HD TOUCH SCREEN.
3. BUILT-IN MICRO PRINTER, EASY TO PRINT TEST RESULTS.
4. EQUIPPED WITH HIGH-PRECISION DIFFERENTIAL PRESSURE SENSOR, DIGITALLY DISPLAY THE PRESSURE DIFFERENCE BETWEEN THE TWO SIDES OF THE SAMPLE.
5. EQUIPPED WITH HIGH-PRECISION GAS FLOW CONTROL, REAL-TIME DIGITAL DISPLAY OF AIR FLOW TO STABLY CONTROL AIR FLOW, MANUALLY SETTING AVAILABLE.
6. TEST TIME CAN BE ADJUSTED ACCORDING TO TEST REQUIREMENTS.
