M22 Millennium II Dual Channel Transmitter


The M22 dual channel universal transmitter has been engineered from the ground-up to include the innovative features that engineers and operators in the field demand, while providing rock solid day-to-day operation, even in the most extreme conditions. With the dual channel option you can cover more area with a single transmitter - Mix & Match, Plug & Play! No other platform can offer this kind of versatility and performance.

Sensors can be easily exchanged, with NE-MOS Solid StateElectrochemicalInfrared andCatalytic Bead sensor technologies available. The Millennium II transmitter automatically recognizes any connected pre-calibrated sensor and maintains an uninterrupted digital signal between them, providing fast response times and over 2000ft (600m) sensor separation.

The intuitive menu interface and non-intrusive commands in Class1 Div1 areas are accessed via the included external magnet and ultra-bright OLED graphic display. This OLED display is completely unique in the market, providing read-outs that are clearly visible in darkness or bright sun, blistering heat or at temperatures as low as -55°C! The transmitter maintains Class1 Div 2 safety levels with the face removed to access the push button controls and test jack outlets. Add our optional intrinsically safe HART® port adaptor for access to the built-in data logging and advanced diagnostics, right at the transmitter via a hand-held communicator.

All this amounts to a detection solution which stands alone in it’s performance, versatility, and efficiency. Only Net Safety offers our unique blend of  technologies which result in more uptime, less consumption, and greater safety coverage.

SMART Sensor Technology
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 connect to the transmitter which instantly recognizes a newly fitted sensor and automatically uploads it’s specific configuration profile.Single or Multi-Channel SMART Controller
No need to purchase additional gas specific detectors. Use with 1 or 2 sensors and mix and match gas types with SMART controllers and sensors.Market-Leading Warranties

  • Infrared & Catalytic Bead Sensors - 5 Year Warranty
  • Solid State & Electrochemical Sensors - 2 Year Warranty
  • Transmitter and Electronics - 3 Year Warranty

Global Certifications
FM Approved Performance, Certified Class 1, Division 1 Explosion proof to CSA, ANSI-UL/ISA, ATEX, INMETRO, and GOST-R Safety and Technical Standards – SIL2 By TÜV SÜD – ABS Marine Approved.

Lowest Power Possible – Widest Input Power Range
Allows for longer sensor separation (+2000ft.) using lighter gauge cabling which means lower installation costs and increased system stablility. Serious conditions can occur during common voltage drops when other detectors will simply stop functioning or shutdown operations by going into fault. The industry’s lowest power draw makes is also ideal for solar, TEG, and turbine powered applications.

Fast Response
Sensor and transmitter continuously communicate digitally, giving you the confidence of stable, accurate protection with leading response times, including the fastest H2S response on the market!

Proven Sensor Technologies
All of our sensors are engineered to be fast and reliable with field-proven designs. These include Nano-Enhanced Metal Oxide Semiconductor (NE-MOS) sensors that “do not fall asleep”; a full range of fast response Electrochemical toxic gas sensors; poison-resistant Catalytic Bead technology with SensorGuard, which prolongs sensor life (see below); and Infrared sensor technology utilizing a dual beam design with no “mirrors” that may become contaminated (“fogged up”) or misaligned.

Proprietary SensorGuard System on Catalytic Bead Sensors
Following a gas leak detection/alarm event, oversaturation (100%LEL) is prevented by our advanced micro-processor automatically terminating the current to the sensor when the presence of concentrated gas remains in the area. This prevents premature sensor burn-out and dramatically increases the sensor’s lifespan. This unique feature allows Net Safety to offer our market-leading 5 year warranty on all our Catalytic Bead sensors.

Unsurpassed Reliability
Net Safety gas detection solutions are field proven in the harshest conditions possible and are have been the preferred choice of operators for years because of their ease-of-use, solid performance, and flexibility.

Bright OLED Display
The only detector on the market with a full graphic OLED display that is easy to read in all ambient lighting conditions and operates down to -55°C!

Analog, Relay, Modbus 485 RTU and HART Communication Protocols
Enhanced communication allows the detector to work seamlessly with external safety equipment.

Easy To Use Menus
Whether you’re disabling a sensor or simply setting display language such as English, French, Portuguese or Spanish, the full text menu instructions make the installation, operation and calibration simple. No manual necessary!

Event Logging
Calibration intervals, low/high gas alarms and faults are time and date stamped, then stored in non-volatile memory. Log up to 980 sequential events.
