| Name | Model | Graduation | Temp.Range (ºC) |
Oxygen Activity | Response Time | Measured Rate |
| Oxygen Probe | QR-TO-1300 | S/R/B | 1200-1760 | 1-1500PPM | Temp: 3-5 s OEF: 4-8 s |
≥98% |
Principle:
"Solid dielectric concentration cell oxygen-content test technology" is applied in oxygen sensor, which allows to measure the temperature and oxygen content of molten steel at the same time. Oxygen sensor consists of oxygen cell and thermocouple. Oxygen content can be calculated from the measured oxygen potential and temperature of the molten steel.
Features:
1) The oxygen activity of the molten steel can be measured directly and rapidly, which is helpful to determine the amount of the deoxidizing agent, and improve the operation of the deoxidation.
2) The oxygen sensor is easy to operate. Measurement results can be obtained just 5-10s after inserting it into the molten steel.
1. Be careful when assembling and removing the parts.
2. Keep dry in the transportational process.
3. The products should be put into cases and stored at warehouses where the relative humidity is less than 80%.
4. Keep the air flowing.
5. The air should not contain harmful gases which may corrode the products.
