▎Product Introduction ：
The NA1000MS integrates NA1000MR controller and NA1000DII transmitters to monitor H₂ concentrations below explosion limits in hydrogen-cooled generators, supporting 16 transmitters for centralized multi-point control with high-performance transmitters converting gas signals to electrical outputs displayed on color LCD, triggering alarms at preset levels for safety measures.
▎Key Features ：
1.Custom sampling systems for generator neutral points/turbine-bearing oil return/cooling water tanks.
2.Explosion-proof metal transmitters (Ex ia IIC T4 Ga).
3.Easy maintenance via core component replacement.
