Mask Respiratory Resistance Tester, Used to Measure the Inhalation and

Functional Features

Features:

1. The instrument is composed of an air source that can adjust the flow rate, a human head mold specified in the standard, two sets of inhalation and exhalation pipeline systems, and a breathing resistance measurement system.

2. The flow sensor has high sensitivity and a very small starting flow.

3. The flow sensor chip adopts a thermal mass flowmeter, which does not require temperature and pressure compensation, which ensures the high-precision measurement of the sensor.

4. Multiple sensors are integrated on a single flow sensor chip, which greatly improves the range ratio of the sensor.

5. The flow sensor has high zero-point stability, high stability of full scale, high accuracy and excellent repeatability of full scale, and has the characteristics of low power consumption, low pressure loss and fast response speed.

6. The data logger adopts a graphic dot matrix liquid crystal with a resolution of 128×64, a full-Chinese interface, and is easy to operate.

7. There is 4M memory in the data logger for recording measured values.

8. The micromanometer sensor adopts a two-wire system, with high precision and good stability; It adopts explosion-proof design, safe and reliable to use.

9. The range of the micromanometer sensor and the zero point are continuously adjustable externally, the damping is adjustable, there is no mechanical movable part, and the maintenance workload is less.

10. The whole instrument adopts a special air path conversion element to ensure that the conversion of the two sets of pipeline systems of exhalation and inhalation is convenient and fast.

Features: The mask respiratory resistance tester is used to measure the inhalation resistance and expiratory resistance of respirators and mask protective equipment under specified conditions. It is applicable to the relevant testing and inspection of ordinary masks, dust-proof masks, medical masks and anti-haze mask products by national labor protection equipment inspection institutions and mask manufacturers.
