As greenhouse gases, carbon dioxide, methane, and sulfur hexafluoride (SF6) are mentioned, among which sulfur hexafluoride is widely used in power-related processes and as an insulating gas in semiconductors. In terms of global warming potential, if carbon dioxide is set at 1, sulfur hexafluoride is 22,800. In recent years, efforts have been made by various companies to prevent the release of sulfur hexafluoride into the atmosphere by installing recovery devices and other measures. Our ultrasonic gas concentration meter is incorporated into such recovery devices and is also used for portable measurement of SF6 concentration. Additionally, in Japan, our ultrasonic gas concentration meter is used for measuring the concentration of alternative refrigerants, which are required to be recovered after use under the Freon Recovery and Destruction Law, as it can measure concentrations that other methods cannot.

Leak tests are conducted to confirm leaks caused by tiny holes, seal failures, and other issues. The helium leak method is often used due to its ease of handling and sensitivity in leak detection. Our ultrasonic gas concentration meter can measure helium concentration in the air at a negative fourth-order level, and the number of customers using it is increasing. In recent years, due to the rising cost of helium, there has been an increase in cases where helium is mixed with air and diluted for use. Our ultrasonic gas concentration meters and gas modules are also used for measuring the concentration of such mixed gases. Additionally, as helium prices have risen, more customers are recovering and reusing helium, and by installing our ultrasonic gas concentration meters on recovery devices, they can visualize concentration for precise management and control.

The shielding gas used in welding varies in gas composition and gas mixture concentration depending on the object being welded. In each company, when performing small amounts of welding, bottled gas is used, while for large-scale welding, tanks, gas mixers, or in-house gas mixing systems are utilized. Our ultrasonic gas concentration meter is used to measure the gas concentration refined by gas mixers and gas mixing systems.

Neon, xenon, and krypton are called rare gases because they exist in very small absolute amounts on Earth. The applications of rare gases are wide-ranging, including electronics, semiconductors, medical fields, and space, and the demand is currently high. Naturally, due to their high prices and preciousness, concentration management is conducted using our ultrasonic gas concentration meters in laboratories and similar settings to ensure efficient gas usage. Target model: US-2T series *There are many other industries where these gases are actively used. Please download our case study collection and consult with us.

It is said that by examining the gas concentration in exhaled breath, one can determine health status. We have combined our zirconia oxygen meter and ultrasonic gas concentration meter into an integrated unit, using the zirconia oxygen meter to measure oxygen concentration and the ultrasonic gas concentration meter to measure carbon dioxide and nitrogen concentrations, allowing it to be used as an exhalation sensor. Target equipment: FG-2UX + US-1T-P *There are many other industries where this is also actively used. Please download our case study collection and consult with us.

A ventilator is a medical device that artificially assists breathing for individuals with insufficient spontaneous respiration over a long period, ranging from several hours to several years. Our ultrasonic gas module is installed in this device and is used to monitor the oxygen concentration supplied to the patient from the device.

Home oxygen therapy is a treatment method for chronic respiratory failure that involves administering oxygen at home, and it is one of the most widely practiced forms of home healthcare in Japan. Among patients with respiratory failure, there are many who are forced to be hospitalized solely for oxygen inhalation. Home oxygen therapy allows these patients to use oxygen concentrators or cylinders to inhale oxygen at home or while out, enabling them to manage their health at home and reintegrate into society. Our ultrasonic gas module is equipped in these home oxygen concentrators and is used for monitoring oxygen concentration. Additionally, an ultrasonic portable gas concentration meter is used to measure the concentration of exhaust gases from the oxygen concentrator to verify its performance.

An ultrasonic gas concentration meter is a gas concentration meter that uses high-voltage ultrasonic elements in its detector. It measures the speed of sound and temperature in a mixed gas of two types to display and output the concentration. It has enabled the measurement range of H2 gas and He gas to be expanded from the conventional range of 0-50% to 0-100%. It has a short startup time, does not require comparison gases, and has no consumable parts, which helps reduce running costs. 【Featured in case studies!】 ○ Home oxygen concentrators ○ Ventilators ○ Exhalation sensors ○ Electronics and semiconductor industry for monitoring and managing gas concentrations in process gas encapsulation ○ Leak testing ○ Greenhouse gas recovery devices (concentration measurement of sulfur hexafluoride and alternative refrigerants) ○ Rare gas (neon, xenon, krypton) concentration management ○ Concentration measurement of shielding gases used in welding (refined in gas mixers and gas mixing systems) *There are many other industries where it is actively used.

Here are some examples of the adoption of the "Ultrasonic Gas Concentration Meter." In a certain process, flammable gases such as hydrogen, methane, and propane are used at arbitrary concentrations. These gases are mixed with oxidizing gases like oxygen in a certain ratio, and when there is a heat source, they can cause combustion explosions. Our products do not have a heat source in the detection section, which allows for the measurement of gas concentration while reducing the conditions under which flammable gases can ignite (however, they are not explosion-proof). [Examples] ■ Application: Measurement of flammable gas concentration ■ Target models: US-IIT Series, US-IT Series *For more details, please refer to the PDF materials or feel free to contact us.
