Explosion-proof dew point meter, oxygen concentration meter, and moisture meter for corrosive gases for chemical plants.

Explosion-proof oxygen concentration meter, dew point meter, explosion-proof dew point meter, moisture meter for corrosive gases, gas purity management, explosion limit management.

The products manufactured in chemical plants are diverse. The manufacturing conditions vary depending on the products being produced, with different management parameters such as temperature, pressure, moisture content, and oxygen concentration. Generally, oxygen concentration meters are used for managing the explosion limits through the control of the three elements of combustion, and it is common to measure oxygen concentration and dew point (PPM moisture content) as impurities to manage gas purity. In the former case, the Oxytron 2000 is often used for control purposes, and the Mini-ICS for concentration management, frequently combined with a sampling system as part of an Inert Gas Control System (ICS). In the latter case, the 2010BR, which can measure PPM with a high response speed, is used for oxygen concentration analysis, while the 210BR is used for percentage levels, and the TK-100-Ex dew point meter is used for dew point measurement. Since hydrogen, solvents, and other flammable gases are often present, explosion-proof certification is often required, and galvanic cell-type oxygen meters are commonly used. For measuring the dew point of compressor air or nitrogen, the non-explosion-proof TK-100 dew point meter is used, and the TMA moisture meter for corrosive gases is also utilized for measuring moisture in corrosive gas environments.
