Oxygen Probe
Oxygen probes measure the temperature and ppm of free oxygen in liquid metal, in less than 10 seconds. When the probe is dipped in the molten metal at certain temperature, the two mV signals generated by the probes are transmitted to the Digital Display Instrument through compensating cable connected to the contact block which is processed and visualized so as to display the values of temperature and ppm of free oxygen; furthermore, the value of %C or %Al dissolved in the bath of liquid steel is automatically calculated.
