Product Description🔷 Product Overview The NDR-H2-1A is a stationary hydrogen gas leak detector that detects hydrogen gas leaks with high accuracy and immediately sounds an alarm via a buzzer and LED when the alarm reaches the 500 ppm alarm threshold. It uses a high-precision catalytic combustion sensor (manufactured in-house). The three-level LED display (Power/Caution/Alarm) allows for at-a-glance confirmation of the status. It operates on AC 100V, eliminating the need for power supply installation. The A-contact relay output (opens when an alarm occurs) allows for connection to external devices. For more information on contact relays, click here. A high-volume buzzer (approx. 93 dB) ensures reliable warnings. Wall-mountable for space-saving installation. *Regular inspection and calibration are required to maintain the detector's performance. For information on regular inspection and calibration, click here. *Please consult us in advance if you are considering installation in a high-altitude location or in a location where maintenance is difficult. Applications: Hydrogen leak monitoring around gas chromatography (GC) equipment; Safety monitoring around hydrogen cutting machines and hydrogen generation equipment; Leak detection around hydrogen cylinders and supply equipment; Safety management of hydrogen use areas in research facilities and analysis laboratories
