For comprehensive performance testing and evaluation of air breathing apparatus and respiratory protection devices.
The MHX-3-C Respirator Comprehensive Tester is a computer-controlled automatic testing system designed to evaluate the comprehensive performance of air breathing apparatus and other respiratory protection devices.
It is suitable for performance testing and evaluation in fire brigade inspection and maintenance stations, respiratory protection product testing institutions, and respirator manufacturing enterprises.
The MHX-3-C Respirator Comprehensive Tester simulates real breathing conditions through an artificial lung system and conducts comprehensive performance testing of air breathing apparatus and related respiratory protective equipment under computer control.
The system measures key parameters such as pressure, breathing volume, and respiratory rate under different working quotas, generating standardized test results to support product quality evaluation and maintenance verification.
With a modular structural design, the equipment consists of a test head mold, artificial lung, computer system, optional printer, and high-pressure main pipe. The system is intuitive to operate, stable in performance, and suitable for long-term use in inspection stations and manufacturing facilities.

The work quota represents the volume of air inhaled or exhaled by the artificial lung during each breathing cycle.
According to GB16556 and GA124-2013 standards, the MHX-3-C offers three selectable work quotas:
| Work Quota Type | Value |
| National Standard | 40 L/min |
| International Standard | 50 L/min |
| International Maximum | 100 L/min |
All work quotas are integrated into the operation software menu. Once selected, the artificial lung operates automatically according to the chosen quota.
