LBT-HW-709B Mask Synthetic Blood Penetration Tester

Description

Product Introduction:

Product Features:

1. A dedicated sample‑holding fixture that can simulate the actual wearing conditions of a mask, providing a designated test area.

2. A specially designed constant-pressure spray device can deliver a specified volume of synthetic blood within a controlled time frame.

3. The test pressure is adjustable, and the pressure gauge displays the pressure value in real time.

4. The spray duration can be set manually, and the timer displays the actual spray time. When the set spray time elapses, spraying stops automatically.

5. The injector can be adjusted vertically and horizontally within a certain range, facilitating testing with masks of different sizes.

6. Equipped with a protection board and a target‑fixing plate to facilitate various experimental procedures.

7. The synthetic blood pressure tank is made of 304 stainless steel, offering robust durability and excellent sealing performance.

8. Synthetic blood reagent and surface tension meter are to be supplied by the customer.
