Product Description The hydrogen alarm (NDR-H2-1A) is a device that detects leaked hydrogen gas with high accuracy and alerts the surrounding area to danger. With a threshold of 500 ppm, it immediately issues an alarm with a buzzer and LED lamp when gas is detected. The power supply is AC100V, and an A-contact relay is provided for the external output. The contact is normally conductive and disconnected when an alarm occurs. It can be used in a variety of ways, from simple installation to device linkage. *Gas alarms are devices that require regular inspection and calibration to maintain accurate detection performance. Please consult us in advance if you are considering installing it in a high place or a place that is difficult to access. We can also propose an installation method that takes into account the maintenance plan. Examples of use ●Around gas chromatography equipment ●Near hydrogen cutting equipment ●Hydrogen cylinder installation location Features ●Uses a proven in-house contact combustion gas sensor: Achieves high reliability and accuracy. ●LED displays hydrogen gas concentration in three stages: Power, trouble, and alarm status can be confirmed at a glance. ●General household AC3V outlet specification: Easy to install and operate. ●Loud buzzer (approx. 100 dB): Ensures attention in an emergency. ●Wall-mounted installation: Can be installed in limited spaces.

Compact hydrogen alarm (NDR-H2-2C) Product description The compact hydrogen alarm detects leaked hydrogen gas and alerts the surrounding area of the risk of gas leakage. While it has the same performance as the standard model (NDR-H2-1A), its compact design allows it to be used in environments with limited installation space. It issues an alarm with a buzzer and LED lamp at a threshold of 500 ppm. The power supply is AC100-240V, and the external output is equipped with a c-contact relay. It can be used in a variety of ways, such as equipment linkage and simple installation. *C-contact type specification. Examples of use ●Around gas chromatography equipment ●Near hydrogen cutting equipment ●Near hydrogen cylinders (places with limited installation space) Features ●Uses our own proven contact combustion gas sensor: Boasts high reliability and accuracy. ●LED displays hydrogen concentration level in three stages: You can check the power supply, trouble, and gas alarm status at a glance. ●Compact body: The compact design allows you to install it in any space. ●Can be used with a general household AC100V outlet: Easy to install and use. ●Loud alarm sound (93dB): Ensures attention in an emergency. ●Can be wall-mounted: Allows for effective use of space. Please feel free to request a quote. If you have any questions regarding the installation environment or maintenance, please feel free to contact us.

Product DescriptionThe hydrogen alarm (NDR-H2-1B) is a device that detects leaked hydrogen gas with high accuracy and alerts the surrounding area with an alarm. The detection concentration threshold is 500 ppm, and when gas is detected, an alarm is immediately sounded by a buzzer (approximately 93 dB) and an LED lamp. The power supply is AC100V. The external output uses a B contact relay (AC250V 1A, resistive load), which is normally open, but when an alarm occurs, the contact closes, allowing for reliable signal transmission to external devices. In this model, the circuit is normally open and closes when an alarm occurs, so it can be easily linked to external buzzers, patrol lights, equipment stop devices, etc. This makes it easy to build a system that reliably and immediately notifies the alarm in the event of an abnormality or safely stops the equipment. *When connecting to an external device, be careful not to exceed the relay contact rating (AC250V 1A, resistive load). It is recommended to use a relay when connecting a high-current device. *Gas alarms are devices that require regular inspection and calibration to maintain accurate detection performance. Please consult us in advance, especially if you are considering installing it in a high place or a place where access is difficult. We can also propose an installation method that takes into account the maintenance plan. *A contact specification model (NDR-H2-1A) is also available separately. Examples of usage ●Around gas chromatography equipment ●Near hydrogen cutting equipment ●Hydrogen cylinder installation location ●When you want to link with a buzzer, patrol light, or stop device Features ●Equipped with a proven in-house contact combustion gas sensor: High reliability and stable detection performance. ●LED 3-stage display: Power, trouble, and alarm status can be confirmed at a glance. ●AC100V power supply specification: Easy installation and operation. ●Loud buzzer (approx. 93dB): Ideal for calling attention in an emergency. ●Wall-mounted installation: Effective use of space. ●Equipped with B contact relay: Signal transmission to external devices is possible when an alarm occurs. Please be careful of the load capacity. We are always available to provide estimates and consultations regarding introduction considerations.
