Regarding the high-sensitivity SSI oxygen probe (600mm in length) produced in Tianjin, the following is a compiled summary of information and recommendations:

1. Key Product Features

Model/Spec: SSI (possibly "Solid State Ion" or a specific brand model), length 600mm, suitable for high-temperature environments (such as kilns, boilers, etc.).

High sensitivity: Rapidly responds to changes in oxygen concentration, suitable for controlling combustion efficiency or environmental monitoring.

Signal Output: Typically in millivolts (mV) or 4-20mA analog signal, some models may support digital communication (such as RS485).

Material: Zirconia (ZrO2) ceramic electrode, resistant to high temperature corrosion; the probe may be equipped with a stainless steel sleeve.

2. Typical Application Scenarios

Industrial Sector: Combustion optimization in steel, cement, and glass industries, atmosphere control for heat treatment furnaces.

Environmental Monitoring: Continuous Emissions Monitoring System (CEMS)

Laboratory: Oxygen partial pressure detection for high-temperature experiments.

3. Selection and Usage Precautions

Temperature Range: Confirm the probe's operating temperature (e.g., 0 to 700°C or higher) and ensure compatibility with a heater or cooling device.

Installation Method: Consider the installation space for a 600mm length; flange or threaded fixation is common.

Compatibility: Verify interface compatibility with existing controllers (such as PID tables, PLCs).

Maintenance: Regular calibration (every 12 months), to prevent dust accumulation or chemical corrosion.

Gas analysis sensor, offering customized oxygen probes.

Tianjin Huaneng: Manufacturer of high-temperature zirconia oxygen sensors, suitable for the power and metallurgy industries.

5. Purchase Recommendations

Parameter Verification: Directly contact the manufacturer for the technical manual to confirm sensitivity (e.g., ±0.1% O2) and response time (e.g., <5 seconds).

Support: Inquiry on calibration services, warranty period, and spare parts supply.
