**【Instrument Features】**  

1. Equipped with a silent air pump.  

2. Equipped with a positive pressure sensor for real‑time pressure monitoring.  

3. Fitted with a precision pressure regulating valve, allowing stepless pressure 

adjustment and setting of technical parameters such as holding pressure and holding time.  

4. Adjustable spray time with automated operation for convenience and speed.  

5. Adopts a mask‑holding device for easy sampling and testing.

**【Technical Parameters】**  

1. **Blood volume:** 2 mL / 60 mL test  

2. **Control mode:** Manual control / push‑button control  

3. **Adjustable pressure:** 16 kPa / 2 psi for high‑pressure output, accuracy 0.1 kPa  

4. **Test pressure range:** 0–16 kPa (2 psi)  

5. **Micro‑pressure gauge range:** 0–0.1 kPa  

6. **Pressure resolution:** 0.1 kPa  

7. **Time accuracy:** 0.1 s  

8. **Test medium:** Synthetic blood (provided by the customer)  

9. **Control method:** Manual / push‑button  

10. **Blood volume:** 2 mL / 60 mL  

**【Test Procedure】**  

Secure the specimen in the specimen holder. At a distance of 30.5 cm from the center of the specimen, 

spray 2 mL / 60 mL of synthetic blood (surface tension 0.042 ± 0.002 N/m) horizontally onto the target 

area of the specimen through a needle with an inner diameter of 0.84 mm, at a pressure of

 16 kPa / 2 psi. Remove the specimen and visually inspect it within 10 s / 60 s.
