Product Description:
YJJ MED-O2-LA 0-100%VOL Medical Rechargeable Battery Electrochemical Oxygen Sensor
Features:
I. Basic Parameters (Original Factory Standard of Winsen)
Detection medium: O₂ (oxygen)
Range: 0 - 100% VOL (full range, covering medical applications)
Sensitivity: At room temperature, air (21% O₂) output 8 - 15 mV (no self-generated power, no power supply required)
Response T90: < 15 seconds
Repeatability error: < 2% FS, full range linear output
Operating temperature range: 0°C - +50°C; Storage: -20°C - +50°C
Humidity: 0 - 99% RH (no condensation, tolerant to ventilator moisture)
Dimensions: Φ32 × 28mm, standard medical cannula interface
Life expectancy: Approximately 2 - 3 years at ambient temperature, 1.5 - 2 years in continuous ventilation conditions
Features: Built-in temperature compensation, anti-humidity, less prone to anesthesia gas poisoning, low drift
II. Working Principle
Galvanic electrochemical cell: Oxygen penetrates the breathable membrane → cathode reduction, anode lead oxidation, generating a micro-voltage proportional to the oxygen partial pressure, MCU collects the voltage and converts it to oxygen concentration.
III. Product Application (Primarily for Medical Purposes)
1. Main medical scenarios
Respirators / Non-invasive ventilators: Real-time monitoring of output oxygen concentration, closed-loop oxygen control, alarm for oxygen concentration exceeding the limit to prevent oxygen poisoning (standard equipment for ICU and emergency ventilators)
Anesthesia machines: Monitoring of the mixed oxygen concentration during surgery, ensuring safe oxygen supply during the operation
Oxygen generators (home use / medical): Real-time detection of output oxygen concentration, automatic alarm when below the set value, machine failure reminder
High-flow oxygen therapy devices, infant incubators, online oxygen concentration monitoring of monitoring devices
2. A few industrial applications
Small oxygen chambers, laboratory air supply equipment, oxygen content monitoring in enclosed spaces.
