[Notice] Sales of this product have been temporarily suspended. We are currently verifying the stability of product performance, and the re-release date is undetermined. We will announce this page or a notice as soon as a replacement product is available. We apologize for any inconvenience this may cause and appreciate your understanding. Product Description: The fixed ammonia alarm (NDS-9A-NH3) detects and displays ammonia (NH₃) concentrations in the air in real time, and reliably sounds an alarm via a buzzer and LED when a dangerous concentration is reached. The measurement range is 0 to 100 ppm, with alarm settings of 20 ppm and 50 ppm, helping to ensure workplace safety. Alarm history and concentration fluctuations are automatically recorded as logs and can be saved in CSV format using a USB memory stick. Furthermore, the relay contact output allows for connection to external devices, making it suitable for integration into factory and facility safety systems. 🔷 Applications: Refrigerant ammonia leak monitoring; Ammonia concentration management in chemical factories and fertilizer manufacturing plants; Safety management of ammonia emissions in livestock facilities (livestock barns, chicken coops, etc.); Ammonia gas monitoring in sewage and wastewater treatment plants

- Applied products
- 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

- Indoor environment
- Work environment measurement
- Electrochemical formula
- Carbon monoxide
- Applied products
- addiction prevention
- Concentration measurement
Product Description: The NDS-9A-CO fixed carbon monoxide alarm monitors CO concentrations in a space in real time and issues an alarm with a buzzer and LED display when a dangerous concentration is reached. Alarm history and concentration data are saved in a log and can be accessed via USB memory. This helps improve the efficiency of facility management and recording. In addition, relay contact output allows for linking with external devices such as exhaust equipment and interlocks when an alarm is issued, making it suitable for incorporation 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 considering installation in high places or locations where maintenance is difficult. 🔷 Applications Fixed CO monitoring in factories and facilities Safety management with real-time concentration display Concentration log storage and management (USB memory compatible) CO alarm system linked to external equipment Enhanced CO safety monitoring using the NDS-9A-CO Main features 8 LED displays + 2-stage buzzer for step-by-step notifications from caution to alarm Real-time CO concentration display with 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 the use of in-house sensor
