Product Description: The stationary hydrogen sulfide alarm (NDS-9A-H2S) is a highly reliable device that detects and displays the concentration of hydrogen sulfide (H8S) in a space in real time, and reliably sounds an alarm with a buzzer and LED when a dangerous concentration is reached. Its main features are as follows: A log function that records and saves alarm history and concentration fluctuations. Data can be saved in CSV format using USB memory. Relay contact output allows for linking with external devices. Ideal for integrating safety systems in factories and facilities. *This device requires regular inspection and calibration to maintain sensor accuracy. For installation locations that are high or difficult to access, we can also propose installation methods based on maintenance plans. Please feel free to contact us for consultation. 🔷 Applications Monitoring hydrogen sulfide at sewage treatment plants and industrial wastewater treatment facilities Monitoring hydrogen sulfide concentrations at chemical plants Safety management at hot spring facilities and areas where volcanic gas is emitted Key Features 2 LEDs and a two-stage buzzer provide clear visual and audible alarm notifications for each stage Real-time H₂S concentration display via 7-segment display Automatic log storage of alarm history and concentration data Log data can be saved in CSV format to USB memory Supports relay contact output linked to alarms, allowing connection to external devices AC100V specification for easy connection and installation via a household outlet Compact design (130 x 90 x 45 mm, 360 g) that can also be wall-mounted High reliability and long life thanks to the use of sensors made by Nemoto Specialty Chemical Co., Ltd.
