The NetSafety M21 Millennium is a Single Channel Gas Transmitter. The M21 automatically recognizes any connected pre-calibrated sensor, and maintains an uninterrupted digital signal between them. This provides a fast response time, and over 600m sensor separation.
The OLED display of the NetSafety M21 provides read-outs that are visible in darkness or in bright sunlight, at high temperatures and even at temperatures as low as -55°C. The M21 maintains Class 1 Div 2 safety levels with the face removed to access the push button controls and test jack outlets.
