Original AII PSR-11-55-HL Oxygen Sensor Oxygen Battery

Original AII PSR-11-55-HL Oxygen Sensor Oxygen Battery

Specs:
Brand: ALL
Model: PSR-11-55-HL
Principle: Galvanic Cell (generates voltage spontaneously, **no external bias needed**)
Range: 0–100% Vol O₂ (for medical high-purity oxygen monitoring)
T90 Response Time: 13 s
Compatible Devices: Heinen Lowenstein Leon Series Anesthesia Machines (HL = Heinen Lowenstein)
Expected Lifespan: About 42 months; shorter in high-oxygen environments
Operating Temperature: 0–45℃
Pressure: 5–30 PSIG, suitable for ventilator/anesthesia machine circuits
Flow Rate: 0.1–10 L/min
Output Signal: mV-level voltage output, linearly proportional to oxygen concentration
Interface: Dedicated 4-pin Molex connector, custom anesthesia machine interface, not interchangeable
Storage Conditions: 0–40℃
Recommended Storage Period: <6 months; keep sealed, early activation will shorten lifespan
