History of Nemoto Group

Since the establishment of the sensor business in 1978, the Nemoto Group has been aiming to become the world's No. 1 company with unique technologies and products that are world-class.
It is still the same, and we are developing our business with the aim of continuing to be a “Global Niche Top Company”.
Here, we will trace the transition of Nemoto, which has been the highlight of the past.

1978

Born as Nemoto Special Chemical Sensor Division

Developed and started selling the ionized smoke sensor NIS-09 as the Nemoto Special Chemical Sensor Division.With this product as the starting point, our progress has begun.

1979

Obtained UL1484 certification for an alarm equipped with a contact combustion type gas sensor

1980

World-renowned technological innovation

By succeeding in developing the world's first sensor that integrates a detection element and a compensation element, we have demonstrated our technological capabilities and have decided to use our products in various fields.

  • ・ Developed contact combustion type LP gas sensor NAP-8A,
    Installed in LP gas alarm
  • ・ Developed contact combustion type city gas sensor NAP-7A.
    Installed in city gas alarms

1984

Developed the world's first contact combustion type sensors NAP-2A and NAP-3A that integrate a detection element and a compensation element, and are installed in various alarms.

1986

Developed semiconductor type carbon monoxide sensor NAP-11A and installed in CO alarm

1990

Further leap forward with global expansion

With the establishment of Shanghai Genben Huaqing Co., Ltd. in Shanghai, China, the Nemoto Group's gas sensor business has expanded overseas.Taking this opportunity, we have made it possible to produce products with technologies that can be used overseas.

1993

Developed and started sales of NAP-2A and NAP-3A as small types of NAP-55A and NAP-66A due to the thinning of gas leak alarms.
