Product Description
FX-182 Synthetic blood penetration tester for medical mask

Guideline
* GB 19083-2010 Medical protective mask technical requirements, 5.5 synthetic blood penetration barrier performance
* YY / T 0691-2008 protective equipment for infectious pathogens, medical masks, synthetic blood penetration resistance test method (fixed volume, horizontal injection)
* YY 0469-2011 Technical requirements for medical surgical masks Blood penetration test device
* ISO 22609: 2004 protective equipment for infectious pathogens, medical masks, test method for penetration of synthetic blood (fixed volume, horizontal injection)
* ASTM F1862-07 Standard Test Method for Penetration Resistance of Synthetic Blood of Medical Masks (Fixed Volume, Horizontal Injection)

Features
1. The mask fixture is a metal human head model, which can fully simulate the actual use state of the mask.
2. The metal human head mold can rotate at a certain angle, which is convenient for sample clamping.
3. Special spray control device can spray a certain volume of synthetic blood within the controlled time.
4. The instrument adopts an air source that can provide (700 ± 25) kPa stable air pressure, which is not affected by the space of the test site.
5. It can simulate the liquid ejection speed corresponding to human blood pressure 10.6kPa, 16.0 kPa, 21.3 kPa (namely 80mmHg, 120mmHg, 160mmHg) for testing.
6. There is a fixed target plate, which can block the high-pressure part of the sprayed liquid flow, and only let the
steady-state flow part be sprayed on the area sample, which increases the accuracy and repeatability of the test.
7. The instrument adopts imported special aluminum brushed panel with metal buttons, which is sensitive to operation and not easy to damage.
8. The 7-inch color touch screen displays the test parameters, and the menu-type operation mode is as convenient as a smartphone.
l9. The core control components adopt STMicroelectronics 32-bit multi-function motherboard.
l10. The instrument code adopts 304 stainless steel, which is durable, neat and clean in appearance. ;
