Description

Product Introduction:

Product Features:

1. One-touch operation; the program automatically controls and completes the test.

2. The mask’s airtightness is standardly tested using a medium-sized headform; a small or large size can be purchased separately. The respiratory valve’s airtightness is tested using a dedicated fixture as standard.

3. Displays flow rate and pressure values in real time.

4. Once the set pressure is reached, the system automatically proceeds to the next test—either for time or leakage volume.

5. PLC touch-screen control; all relevant operations can be performed via the touch screen.

6. It can integrate the air-tightness testing of both the breather valve and the mask into a single device.

Applicable Standard:

GB2626
