The Net Safety M2B Millennium II BASIC Universal Transmitter (formerly branded Net Safety) is a robust and reliable safety solution delivering highly accurate monitoring of toxic and combustible gases. Utilizing our stateof-the-art SMART sensor technology, it provides a flexible detection platform that includes all the advanced features users in the field demand with complete ease-of-use and operation.

Designed for applications that require a local, full-featured transmitter interface but do not require a character display. The Millennium II BASIC includes bright LED indicators for Power/Alarm/Fault conditions with an optional HART® interface.

A truly universal transmitter, the M2B can be fitted with a full range of both toxic or combustible gas sensors. SMART (Self Monitoring Analysis and Reporting Technology) sensors are pre-calibrated and easily connect to the transmitter which automatically recognizes a newly fitted sensor and uploads 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 BASIC is approved to international hazardous area safety standards for operation and performance.

Multiple communication protocols allow the M2B Transmitter to work seamlessly with your system, including wireless communication via a THUM™ WirelessHART® Adaptor.

Solid state Nano-Enhanced MOS sensors that have fast H2S response and do not "fall asleep"; poison-resistant Catalytic Bead with SensorGuard technology, which greatly prolongs sensor life; Infrared sensor technology utilizing a dual beam design with no mirrors that may become contaminated ("fogged up") or misaligned; as well as a full range of Electrochemical toxic gas sensors.
