Regarding oxygen probes produced by Sino-foreign joint ventures in the Beijing area (available in lengths of 600mm, 800mm, 1000mm, and 1200mm), the following is a compilation of comprehensive information and recommendations:

1. Common Application Scenarios of the Product

Oxygen probes are commonly used in industrial gas detection (such as boilers, kilns, heat treatment, etc.), with different lengths corresponding to the following applications:

600mm/800mm: Suitable for small to medium-sized equipment or environments with limited space.

1000mm/1200mm: Suitable for large-scale industrial equipment (such as steel smelting, glass melting furnace), requiring deep penetration into high-temperature areas for inspection.

3. Recommended Key Parameters

Ensure the following technical details are confirmed during the selection process:

Measurement Principle: Zirconia (ZrO2) or electrochemical formula?

Temperature Range: Is it suitable for high-temperature environments (such as above 1200°C)?

Output Signal: 4-20mA, RS485, or others?

Protection Rating: IP65/IP67 and others, ensuring protection

5. Cautionary Notes

Certification Standards: Confirm compliance with CE, RoHS, or Chinese GB standards.

After-sales service: Joint-venture brands generally offer technical support and warranty; terms should be clarified.

Customization Requirements: If standard length is not applicable, please inquire about customization support.
