3. Product Features

1. Use the flow lock card to adjust the flow to ensure that the flow fluctuation is less than 5% during the long-term sampling process of low flow.

2. Select a more stable air pump suitable for low flow, and the negative air pressure is more than 5000Pa.

3.4 digits display timing, working noise <60dB(A).

4. There is a filter element inside to prevent particles from being sucked into the pump.

5. With undervoltage indication and buzzer alarm.
