The Net Safety M22 Millennium II Dual Channel Universal transmitters (formerly branded Net Safety) have been engineered from the ground-up to include the innovative features that managers and operators in the field demand, while providing rock solid day-to-day operation, even in the most extreme conditions. The Millennium II redefines what you expect from a fixed gas detection solution.

The transmitter can be fitted with a wide range of toxic and/or combustible gas sensors. SMART (Self Monitoring Analysis and Reporting Technology) sensors are pre-calibrated and easily connected to the transmitter which recognizes a newly fitted sensor, automatically uploading it's specific configuration profile.

Sensor and transmitter continuously communicate digitally, giving you the confidence of stable, accurate protection with fast response times even over long separation distances.

The Millennium II is approved to international hazardous area safety standards for operation and performance.

English, French, Portuguese or Spanish display languages included. The full text menu makes installation, operation and calibration simple. No manual necessary!

The only full graphic OLED display available, easy to read in all ambient lighting conditions and operates down to -55°C!

Multiple communication protocols allow the M22 to work seamlessly with your new or existing system.

All sensors are engineered to be fast and reliable with field-proven performance in the harshest industrial conditions possible. These include Nano-Enhanced Metal Oxide Semiconductor (NE-MOS) toxic gas sensors that do not "fall asleep" and a full range of fast response Electrochemical toxic gas sensors. For combustible gas detection, poison resistant Catalytic Bead technology with SensorGuard, which greatly prolongs sensor life and Infrared sensor technology utilizing a dual beam design with no mirrors that can become contaminated ("fogged up") or misaligned.
