DRK260 Respirator Resistance Tester

Introduction
The respirator resistance tester is used to measure the inspiratory resistance and expiratory resistance of respirators and respirator protectors under specified conditions.It is applicable to the national labor protection equipment inspection institutions, mask manufacturers for the general masks, dust masks, medical masks, anti-smog masks products of the relevant testing and inspection.

Standard

GB 19083-2010 Technical requirements for medical protective masks

Features:

1. High-definition LCD display.

2. Digital differential pressure meter with high precision imported brand.

3, high precision imported brand of digital flowmeter,with high flow control accuracy features.

4. The respirator resistance tester can set up two modes: exhalation detection and inhalation detection.

5. Automatic pipeline switching device of respirator solves the problem of pipe extubation and wrong connection when testing.

6.Measure the exhalation resistance with the dummy head successively placed in 5 defined positions:

--facing directly ahead

--facing vertically upwards

--facing vertically downwards

--lying on the left side

--lying on the right side
