In the 1990s, due to the complete elimination of freon used for cleaning, new reflow ovens that meet or exceed the required quality were developed. To prevent oxidation during the loading of components onto the substrate, various companies began developing nitrogen reflow ovens. The atmosphere gas inside the reflow oven is very dirty, and our zirconia-type oxygen meters, which are resistant to harsh environments, have been widely adopted.

In paper mills, steelmaking, incinerators, and other industries, a large amount of oxygen is required in the processes. Oxygen generation systems extract oxygen from the air and are used to improve combustion efficiency in furnaces and in various processes. Additionally, smaller units are used for home healthcare purposes. Our zirconia-type oxygen analyzers are generally used for industrial oxygen generation systems.

In chemical plants and similar facilities, there are many processes that require nitrogen, and nitrogen lines are installed throughout the factory. The nitrogen generation unit separates nitrogen from the air and supplies it to the factory lines. Our products are incorporated into the nitrogen generation unit to measure residual oxygen concentration and are used for system control, among other purposes.

In Japan, various goods are imported from countries around the world. The transportation methods are either by air or by ship, but in the case of ships, there is significant swaying, and for chemical products, there is a risk of explosion due to friction. Therefore, nitrogen generation devices are used to lower the oxygen concentration and prevent explosions in advance. Additionally, for food products, nitrogen generation devices are also used to lower and manage the oxygen concentration to prevent spoilage. Our zirconia oxygen analyzers are built into such nitrogen generation devices to monitor the oxygen concentration.

When transporting heavy oil with a tanker, friction between the heavy oil and air inside the tank can cause an explosion due to turbulence during operation. To prevent this, tankers mix nitrogen or inert gases with the air to avoid explosions. Nitrogen is generated using a nitrogen generation unit, and inert gases are reused from boiler exhaust. This is called the Inert Gas System (I.G.S). Our oxygen meters are incorporated into the I.G.S, measuring the O2 concentration in the exhaust gas, and are actively used worldwide to prevent explosions during operation, as well as during loading and unloading.

The atmospheric pressure is 1 atmosphere (1013.25 hPa). A space with lower pressure than this atmospheric pressure is called a vacuum. By creating a vacuum, it is possible to prevent the oxidation of processed materials, which is why vacuum devices and vacuum furnaces are used in many material product processes. Our zirconia-based oxygen analyzer can measure a range from ppm O2 concentration to 10×-30 atm O2.

Furnaces are used in various applications, not limited to steelmaking, ceramics, environmental technology, and non-ferrous metals. By simply changing the temperature, fuel, and air volume, the properties of the materials being heat-treated can change significantly. For example, in the steelmaking process, it is necessary to create a reducing atmosphere inside the furnace, which requires an oxygen-free environment. Each user can improve quality and enhance production efficiency by controlling and managing temperature and combustion. Our oxygen meters can measure the atmosphere inside the furnace. They can manage ranges such as %, ppm, mV, -%O2, and 【CO+H2】%, allowing for the measurement and management of oxidation-reduction. Applicable models: TB-2F series, TB-2G, and others. *There are many other industries where our products are actively used. Please download our case study collection and consult with us.

In the 1970s, during the period of rapid economic growth, photochemical smog frequently occurred in Japan, often leading to the cancellation of physical education classes in elementary and junior high schools. This phenomenon arises from the poor combustion efficiency of fuel and air, resulting in the emission of nitrogen oxides and other pollutants into the atmosphere. In the 1980s, to reduce fuel costs, energy-saving initiatives were strengthened, allowing for efficient combustion without wasting fuel through the control of boiler combustion and oxygen concentration management. Additionally, there have been significant improvements in environmental aspects, and the occurrence of photochemical smog has been on the decline.
