LBT-HW-702 Mask Breathing Resistance Tester

Description

Product Introduction:

Product Features:

1. The system is fully controlled via a PLC touch screen, with all relevant operations performed through the interface.
2. You can choose to perform either the exhalation test or the inhalation test.

3. The micro-manometer sensor employs a two-wire configuration, offering high accuracy and excellent stability.

4. The program includes a no-load test mode, facilitating the assessment of overall system performance, particularly that of the sensor and flowmeter.

5. The test process displays the resistance value in real time, and upon reaching the set test duration, it automatically locks the maximum resistance value.

6. Equipped with a built-in silent, oil-free dedicated air compressor and a professional-grade vacuum pump, eliminating the need for customers to configure these components themselves.

7. The test automatically starts the air compressor or vacuum pump and shuts it down automatically upon completion.

8. Equipped with a dedicated large-size headform for testing (small and medium sizes available as optional accessories).
