First, the main purpose:
       A certain amount of synthetic blood is sprayed horizontally on one side of the mask under test with a certain pressure and distance, and the penetration of the synthetic blood on the other side of the mask is observed. Produced in accordance with relevant standards, mainly using medical protective masks for resistance to synthetic blood penetration tests. Applicable to medical mask mask manufacturers, quality supervision, scientific research, wearing and other units
Second, the main features:
      1. The special sample fixing device can simulate the actual use of the mask, leaving the test area.
      2. A special constant pressure injection device can inject a certain volume of synthetic blood in a controlled time.
      3. It can simulate the corresponding spraying speed under different pressures for testing.
      4. The pressure gauge displays the pressure value in real time.
      5. The timer displays the test time in real time.
      6. Customer-made synthetic blood reagents.
