▎Product Introduction ：
The NA1000MS consists of NA1000MR multi-channel alarm controller and NA1000A gas detector for monitoring target gas concentrations in ambient air, supporting multiple probes for centralized multi-point control. The NA1000A's diffusion-based sensor detects NH₃ concentrations (particularly indoors), with processed signals displaying locally while transmitting via (4~20)mA current, RS485 communication and alarm contacts.
▎Key Features ：
1.Centralized bus or independent zone power supply options.
2.Dual-level concentration alarms with real-time monitoring.
3.High-sensitivity anti-poisoning sensors with automatic aging compensation.
4.Automatic sensor fault detection and high-concentration gas limit function.
5.Startup self-test with self-diagnosis/self-repair and adjustable calibration.
6.Automatic sensor failure alarm to prevent missed detections.
