Detailed Product Description
AO2 PTB-18.10 Oxygen Sensor for Medical & Emission Analyzers
The AO2 (PTB-18.10) is a high-performance electrochemical oxygen sensor designed specifically for gas analysis instruments. Known as the "industry standard" for O₂ measurement, it utilizes a specialized internal capillary to ensure linear output and stable performance even in varying pressure environments.
Unlike standard sensors, the PTB-18.10 features a reinforced body and a 3-pin Molex connector, making it a robust, plug-and-play solution for high-precision gas monitoring. Whether for precision medical diagnostics or rugged automotive testing, the AO2 provides the accuracy that engineers demand.
Product Highlights
  • High Precision & Linear Output: Provides accurate 0-100% O₂ measurement with excellent linearity, ensuring reliable data for medical and industrial gas analysis.
  • Fast Response Time: Features a T95 response time of less than 15 seconds, critical for real-time monitoring in automotive emission testing and safety equipment.
  • Broad Compatibility (PTB-18.10): Fully compatible with leading brands of combustion analyzers and medical oxygen monitors (direct replacement for CiticeL AO2).
  • Long Operational Life: Designed for durability with a 2-year expected life in normal air, minimizing maintenance costs and equipment downtime.

FAQ
Q1: Is this sensor compatible with my existing emission analyzer?
Yes. The AO2 (PTB-18.10) is a standardized sensor widely used in automotive emission testers (like Bosch, Sun, Crypton) and medical oxygen concentrators. If your current sensor has a 3-pin Molex connector and matches the AO2 profile, it is a direct fit.
Q2: How do I ensure the authenticity of the sensor?
Fradwell supplies only factory-fresh sensors with verified batch numbers. Each AO2 sensor is shipped in its original sealed anti-static packaging to ensure zero exposure before installation.
Q3: What is the shelf life of the AO2 sensor?
We recommend installing the sensor within 6 months of purchase. Store in a cool, dry place (5°C to 20°C) to maximize its operational lifespan.
