Applied products

Introducing gas detectors and application products from Nemoto Specialty Chemical Co., Ltd. We offer a range of products that contribute to safety measures, including portable carbon monoxide alarms and hydrogen detectors.

Portable carbon monoxide (CO) detectors are widely used for worker safety management in industrial sites such as steelworks and factories. Equipped with a highly sensitive electrochemical gas sensor manufactured in-house, it supports two-stage alarms of 50ppm and 150ppm. It also has an alarm function based on the accumulated concentration, and is characterized by stable operation thanks to its long-life battery. As a portable gas alarm, it provides the optimal solution for preventing CO poisoning at work sites.

Our hydrogen (H₂) alarm NDR-H2-1A uses a catalytic combustion gas sensor to detect hydrogen gas leaks. It sets a detection concentration threshold of 500 ppm and immediately issues an alarm with a buzzer and LED lamp. For the external relay output, you can select either the a-contact specification or the b-contact specification at the time of shipment (switching during operation is not possible). Please specify the specification when ordering according to the installation environment and purpose. With an AC100V power supply, this hydrogen safety device can be easily installed in factories, laboratories, hydrogen stations, etc.

Our compact hydrogen alarm is equipped with a catalytic combustion gas sensor for hydrogen gas leak detection, and has the same detection performance as the standard model (NDR-H2-1A), but with a compact housing. It can also be used in environments with limited installation space or for equipment integration. The detection concentration threshold is 500 ppm, and an immediate alarm is issued with a buzzer and LED lamp. The external relay output uses a c-contact.
