| Probe Material | High-Temperature Alloy Sheath, Zirconia Ceramic Core |
3. Selection Recommendations
Length Selection: Choose based on the airflow path at the installation location or the furnace depth to ensure the probe's sensitive element can reach the target measurement area.
800mm: Limited space or high gas flow scenarios.
1000mm: Standard industrial furnace (such as heat treatment furnace).
1200mm: Large-scale combustion equipment (such as power plant boilers).
Accessory Equipment: Requires a transmitter (such as Marathon's MX series) and a calibration gas device.
4. Cautionary Notes
Installation Method: Insert vertically or horizontally to avoid mechanical stress.
Calibration Maintenance: Regularly calibrated using standard gas
Common Application Fields
Steel industry: Blast furnace and hot blast stove flue gas monitoring.
Glass Manufacturing: Enhanced melting and combustion efficiency.
Waste Incineration: Control of exhaust oxygen content.
