The Metron PS-420 is a professional-grade patient simulator designed for accurate testing and calibration of multi-parameter patient monitors and biomedical equipment. It is a robust, compact unit widely used in clinical engineering and service laboratories for verifying vital-sign monitoring systems.

Key Features & Technical Specifications:

• Multi-Parameter Simulation: Simulates a wide range of physiological signals including ECG, respiration, invasive and non-invasive blood pressure, temperature, and cardiac output.
• ECG Output: True 12-lead ECG simulation with independent lead outputs referenced to RL.
• ECG Lead Impedance Options: 500 Ω, 1000 Ω, 1500 Ω, 2000 Ω for leads I, II and III.
• ECG Rates: Wide selectable heart rate range from 30 to 300 BPM with ±1% frequency accuracy.
• Amplitude Accuracy: ECG amplitude up to 2.0 mV with ±2% precision on Lead II.
• Signal Waveforms: Supports multiple waveform types (adult/pediatric, square, sinusoidal, triangular) and pacemaker pulse simulation.
• Respiration Simulation: Fully variable respiratory waveforms for testing respiration rate channels.
• Pressure Outputs: Non-invasive blood pressure simulation via two output channels (PS-420 model).
• Temperature & Cardiac Output: Outputs available (with appropriate transducers and adapters) for temperature and cardiac output testing.
