Dew point meter, oxygen concentration meter, temperature and humidity meter, hygrometer for steelmaking.

Measurement using dew point meters (moisture meters), oxygen concentration meters, etc. for managing the atmosphere inside the furnace.

Managing the moisture content and oxygen concentration in the furnace affects the quality of steel products. The mainstream method for moisture measurement is the capacitive TK-100 dew point meter using aluminum oxide, but some applications also use the capacitive TE-660 dew point meter with polymers and the EE33 temperature and humidity dew point meter, which can measure under high temperature and high humidity conditions. Additionally, for cases requiring fast response and accuracy, the mirror-cooling (mirror-type) dew point meters MBW973/MBW573 are used. For measuring oxygen concentration, the 2001LC galvanic cell oxygen meter, which can respond quickly to measurements down to PPM, and the 1000RS portable oxygen meter are utilized. Furthermore, the purity of recycled gas and the purity of refined hydrogen are measured using the TK-100 dew point meter and the TMA series moisture meters for corrosive gases.
