Description
Product Introduction:
The mask breathing resistance tester is used to measure the inhalation and exhalation resistance of respirators and mask-type protective equipment under specified conditions. It is suitable for use by national occupational safety and health testing institutions and mask manufacturers to conduct relevant tests and inspections on ordinary masks, dust‑proof masks, medical masks, and anti‑smog masks.
Application areas
It is used by national occupational safety equipment inspection agencies and mask manufacturers for the testing and certification of ordinary masks, dust‑proof masks, medical masks, and anti‑smog masks.
Product Features:
1. The instrument consists of an air source with adjustable flow, a human head model conforming to standard specifications, two separate tubing systems for inhalation and exhalation, and a respiratory resistance measurement system, among other components.
2. The flow sensor features high sensitivity and a very low start-up flow rate.
3. The flow sensor chip employs a thermal mass flow meter, eliminating the need for temperature and pressure compensation and ensuring high‑accuracy measurement.
4. Multiple sensors are integrated onto a single flow‑sensor chip, significantly increasing the sensor’s span ratio.
5. The flow sensor exhibits excellent zero-point stability, high full-scale stability, high accuracy across the entire measurement range, and outstanding repeatability, while also featuring low power consumption, minimal pressure loss, and rapid response.
6. The data logger features a 128×64 graphical dot-matrix LCD with a fully Chinese-language interface, ensuring convenient operation.
7. The data logger is equipped with 4 MB of memory for recording measurement values.
8. The micro‑manometer sensor employs a two‑wire configuration, offering high accuracy and excellent stability; its explosion‑proof design ensures safe and reliable operation.
9. The micro‑manometer sensor features a continuously adjustable range and zero point, adjustable damping, and no mechanical moving parts, resulting in minimal maintenance requirements.
10. The entire instrument employs a specialized gas‑path switching component, ensuring convenient and rapid switching between the expiratory and inspiratory tubing systems.
