Features:

I. Core Parameters (25℃, ambient air)

Target gas: Oxygen O₂

Measurement range: 0–100% O₂ (full range coverage)

Output signal: 7–13 mV (@20.9% O₂, linear output)

Response time T90: < 5 s (extremely fast response)

Operating temperature: 0℃ ~ +50℃ (normal environment)

Storage temperature: -20℃ ~ +60℃

Life span: 5 years + (solid-state electrolyte, anti-drying)

Shock resistance: Excellent (solid-state electrolyte, resistant to vibration)

Certifications: PTB-A 18.10, RoHS, EN ISO 13485

II. Working Principle

Polarographic (Galvanic Cell) Principle:

Oxygen passes through the permeable membrane and enters the solid-state electrolyte;

At the cathode, a reduction reaction occurs, while at the anode, oxidation takes place, generating a micro-voltage (mV level) proportional to the oxygen concentration;

Built-in solid-state electrolyte, no leakage, long lifespan, resistant to high and low temperatures and vibrations;

Output directly connected to the mV level circuit, no need for complex amplification.

III. Main Applications (Core Scenarios)

1. Medical Equipment (Most mainstream)

Respirators, anesthesia machines: Monitoring inhalation / exhalation oxygen concentration, preventing hypoxia / oxygen poisoning

Monitoring devices, oxygen analyzers: Monitoring of medical gas concentrations

2. Industrial Gas Monitoring

Air separation oxygen production: Online monitoring of high-purity oxygen / nitrogen

Enclosed spaces: Tunnel, mine, ship cabin, cold storage oxygen content alarm (preventing hypoxia)

Power / boiler: Oxygen content monitoring in flue gas (burning efficiency control)

3. Automotive and Exhaust Analysis

Exhaust analyzer: Detecting O₂ concentration in exhaust (fuel-air ratio)

Automotive maintenance testing equipment

4. Aerospace and Research

Cabin / compartment oxygen monitoring, laboratory gas ratio adjustment, environmental chamber
