Posted "Nissha Products to Contribute to a Hydrogen Society"

Hydrogen is expected as a clean energy for the realization of a carbon-free society. We are contributing to the building of a hydrogen society through various products.

Outline of gas sensors

Nissha Group gas sensors are built into gas alarms for preventing carbon monoxide poisoning and gas explosions, and even into air purifiers and air conditioners. These are also applied to breath alcohol checkers for the prevention of drunk driving and to fields that support the safety and comfort of automobiles.
Meanwhile, we are developing applied equipment based on the sensors. For example, using the Nissha Group Sensor Gas Chromatograph—a compact, lightweight, and competitively priced device for measuring ultralow parts-per-billion level concentrations of gas—we offer products targeting the environmental field as well as the healthcare field, such as halitosis analyzers. life and short detection time.
It is expected that gas sensors will be applied to an even wider range of purposes such as fuel cell vehicles, medical and POCT (Point of Care Testing) in the future.

Element technology

Equipped with all design technologies necessary for gas sensing

Gas element technology

Semiconductor gas sensors, other gas sensors, and applied equipment in recent years feature ever more advanced sensitivity and accuracy, and are used in an expanding range of fields. For accurate detection of the target gas, however, it is not enough that the sensor alone incorporates excellent technologies. We develop and manufacture everything from gas sensors alone to finished products such as modules, checkers, and analyzers. By being equipped with all elemental technologies necessary for gas sensing, we offer products that meet customer needs—high sensitivity, high accuracy, easy operability, and high reliability—in a broad range of fields including safety, environment, healthcare, automobiles and measurement.

Gas sensor design technologies

Material synthesis –The key to gas sensing–

We prepare original materials to manufacture sensors tailored to the properties of the target gas. Material synthesis is the key to gas sensing and an area that best showcases the expertise of Nissha Group.

Micromachining –Development of small size, low power consumption sensors–

Sensor miniaturization presents numerous advantages, from power and cost savings to quick response times and expanded scope of application. Nissha Group uses proprietary micromachining technologies in processes such as electrode machining and the formation of gas-sensing bodies to develop and manufacture small size, low power consumption sensors including MEMS* gas sensors.

Facility design –Manufacturing equipment designed in-house–

FIS factory

Manufacturing gas sensors, including micromachining, requires special processes and equipment. Nissha Group designs its own equipment, such as automatic applicators of gas-sensing materials, to realize inimitable small size, high performance, and high reliability.

Product design technologies

Structural design –The optimal design for each product–

Each component of the gas sensor serves a purpose, down to the last tube. By tailoring various elements such as structure, layout, and materials to the purpose of the product, we can equip the gas sensor with unique functions.

Control circuit design –Realizing high sensitivity and low noise–

Improvements in sensitivity pose a challenge: the gas sensor is that much more susceptible to noise, or gases other than the target gas present in the surrounding environment. Control circuit design is an important means of controlling this noise as well as ensuring user-friendliness of the product including the software. Nissha Group designs original control circuits to present products that play up the strengths and play down the weaknesses of various sensors.

Software development

Nissha Group develops original software tailored to each product for easy operation even without specialized knowledge. The software can be customized according to customer needs.
