HP-KHZ-E respiratory resistance tester is used to measure the inspiratory resistance and expiratory resistance of respirators and masks under specified conditions. It is applicable to the testing of export products and meets the European standard. It also meets the relevant testing and inspection of ordinary masks, dust masks, medical masks and anti haze masks carried out by domestic labor protection articles inspection institutions and mask manufacturers.

Features of HP-KHZ-E respiratory resistance tester:

1. Touch screen control, menu operation, easy to operate.

2. At the same time, it can meet the European and national standards, and the Chinese and English operation menu can be switched.

3. The unit can be selected and PA and mbar can be switched freely.

4. The standard head mold can be rotated in five directions to simulate human body's real inhalation and exhalation, meeting the European standard

5. The micro pressure sensor is explosion-proof, safe and reliable.

6. The special air circuit conversion element is adopted to ensure the convenient and quick conversion of the two sets of pipe systems.

7. Equipped with micro printer, it is convenient to print test results on site.

8. The instrument is composed of air source with adjustable flow, standard human head mold, two sets of pipeline system for inhalation and exhalation, respiratory resistance measurement system, etc.

9. Two modes of exhalation detection and inhalation detection can be set.
