Product Description

Fixed hydrogen sulfide alarm NDS-9A-H2S monitors the concentration of H₂S (hydrogen sulfide) in the space in real time,
When dangerous concentrations are reached Buzzer and LED display This ensures a reliable alarm.
Alarm history and concentration data Automatic log saving and can be easily retrieved using a USB memory stick.
It is designed to help streamline facility management and record-keeping operations.
In addition, when an alarm occurs Relay contact output This allows for linking with external devices such as exhaust equipment and interlocks.
It can be easily integrated into factory or facility safety systems.

*Regular inspection and calibration are required to maintain sensor performance.
If you plan to install the product in a high place or in a location where maintenance is difficult, please consult us in advance.
