For customized needs of the Beijing 1602000 series marathon oxygen probe, here is a step-by-step guide:

1. Specify requirements parameters

Application Scenarios: Confirm oxygen probe usage for marathons (such as athlete's blood oxygen monitoring, environmental oxygen content detection) or other industrial/medical applications.

Measurement Range: Typically 0-25% or 0-100% (depending on gas or oxygen demand).

Precision Requirement: ±0.1% or higher medical-grade standard.

Output Signal: Analog (4-20mA/0-10V) or Digital (RS485/I2C).

Environmental Adaptability: Waterproof, shockproof, wide temperature range (20℃~50℃).

2. Select sensor types

Optical sensor

Zirconia Sensor: For high-temperature industrial use, not suitable for marathon scenarios.

3. Customization Key Steps

Protocol Matching: Ensure compatibility with existing devices' communication protocols (such as fitness trackers, environmental monitors).

Structural Design:

Portable: Lightweight (<50g), low power consumption (battery life >24h).

Industrial Use: IP67 protection, electromagnetic interference resistance.

Calibration Service: Offers factory calibration or user self-calibration feature.

5. Testing and Certification

Mandatory Inspection Items: Linearity Test, Response Time, Cross-Interference (e.g., CO2 influence).

Certification Requirements:

Medical Use: Requires CFDA Certification.

Industrial Use: CE/ROHS Certified
