- addiction prevention
Product Description: The NDS-9A-H2S fixed hydrogen sulfide alarm monitors the H₂S (hydrogen sulfide) concentration in a space in real time and reliably sounds an alarm via a buzzer and LED display when a dangerous concentration is reached. Alarm history and concentration data are automatically saved in a log and can be easily retrieved using a USB memory stick. Its design helps streamline facility management and record-keeping. In addition, relay contact output allows linking with external devices such as exhaust equipment and interlocks in the event of an alarm, making it easy to incorporate into safety systems for factories and facilities. *Regular inspection and calibration are required to maintain sensor performance. Please consult us in advance if you are planning to install the alarm at high altitudes or in locations where maintenance is difficult. 🔷 Applications Monitoring hydrogen sulfide at sewage treatment plants and wastewater treatment facilities Monitoring H₂S concentrations at chemical plants Safety management at hot spring facilities and in areas where volcanic gas is emitted Managing the risk of hydrogen sulfide leaks at factory facilities Main Features 8 LED displays + 2-stage buzzer provide step-by-step notifications from caution to alarm Real-time H₂S concentration display using 7-segment LED Automatic log storage of alarm history and concentration data Data can be saved to USB memory in CSV format Alarm-linked relay contact output for easy connection to external devices AC100V specification allows for easy power supply from a household outlet Wall-mountable, compact design (130 x 90 x 45 mm / 360g) High reliability and long life thanks to in-house developed sensors
