Used for measuring the temperature of molten steel and high-temperature molten metal, thermocouple tips is disposable. Based on the thermoelectric effect of metals, it works according to the Electric Potential Difference between its two wires to work out the temperature of the molten metals.

1, To select the appropriate length of protective paper tube and temperature measuring gun according to the object and scope of the measurement
2, Attach the disposable thermocouple to the temperature measuring gun, make the pointer of the secondary instrument (or digital display) back to zero. Begin to measure.
3, It is recommended to insert the disposable thermocouple in to the molten steel at the depth of 300-400mm. Do not touch the furnace wall or scum. Bring up the temperature measuring lance immediately after the secondary instrument get results. The soak time of disposable thermocouple in molten steel should less than 5 seconds, otherwise the gun may be burned out.
4, Change the used thermocouple into a new one, and pause for a few minutes to get ready for the next measurement.
Be careful when assembling and removing the parts. Keep dry in the transportational process. The products should be put into cases and stored at warehouses where the relative humidity is less than 80%. Keep the air flowing. The air should not contain harmful gases which may corrode the products.
