ANSI EN149 Face Masks Dead Space Tester

This mask dead space test machine automates the detection of CO2 concentration within the dead space of EN149-compliant filtering half masks (FFP1/FFP2/FFP3) and other respirators. It evaluates compliance with EN149:2001+A1:2009 Clause 8.3.1 and GB2626 standards by simulating human breathing patterns and analyzing inhaled/exhaled air composition.

Key Features
Advanced CO2 Analysis:Triple infrared CO2 sensors with a measurement range of 0–12% (vol.) and accuracy of ±0.1% for real-time data acquisition.Automated calculation of average CO2 volume fraction to determine mask breathability and safety thresholds.
Dynamic Breathing Simulation:Adjustable respiratory frequency (10–40 cycles/min) and tidal volume (0.5–3.0 L/min) to mimic diverse physiological conditions.
Integrated mechanical lung simulator with sinusoidal airflow control for realistic testing.Intelligent Control System:7-inch industrial touchscreen for parameter setup (e.g., test duration, airflow rates) and real-time monitoring of CO2 levels, airflow, and ambient temperature.Self-calibration and auto-diagnostic functions to ensure consistent accuracy.
