LBT-HW-717 Respirator Radiant Heat Performance Tester

Description

Product Introduction:

Manufactured in accordance with relevant standards, it is primarily used for thermal radiation resistance testing of respirator masks, breathing hoses, medium-pressure hoses, air supply valves, and other components. It is suitable for respirator manufacturers, quality‑control agencies, research institutions, and similar organizations.

Product Features:

1. PLC touch-screen intelligent control system, with a simple and user-friendly test interface.

2. Stainless steel reflector panel, used to enhance the thermal radiation performance applied to the mask.

3. Metal headform assembly, heat- and corrosion-resistant, compatible with a face mask, and allows for unrestricted breathing.

4. The metal headform is mounted on a sliding rail, allowing its horizontal position to be adjusted to regulate the distance between the mask and the radiation source.

5. Equipped with a water-cooled heat flux meter for measuring thermal radiation flux at a standard distance.

6. Equipped with an artificial lung respiratory device, the system generates sinusoidal breathing waveforms, accurately simulating human respiration.

7. Both respiratory rate and tidal volume can be freely set via the PLC touch screen.

8. The test can be terminated automatically at the set time or manually.
