The Millennium II (M22) dual channel universal
transmitters 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.

Dual Channel Transmitter
A single transmitter which accepts two sensor inputs and
provides two separate output signals, reducing initial
purchasing and installation costs.
Universal Transmitter
The transmitter can be tted with a wide range of toxic
and/or combustible gas sensors. Sensors are pre-calibrated
and easily connected to the transmitter which recognizes a
newly tted sensor, automatically uploading sensors’ speci c
con guration pro le.
Digital Communications
Sensor and transmitter continuously communicate digitally,
giving you the con dence of stable, accurate protection with
fast response times even over long separation distances.
Easy To Use Menus
English, French, Portuguese, or Spanish display languages
included. The full text menu makes installation, operation, and
calibration simple. No manual necessary!
Superior OLED Display
The only full graphic OLED display available, easy to read in all
ambient lighting conditions.
Analog, Relay, Modbus® RS485 RTU
Multiple communication protocols allow the M22 to work
seamlessly with your new or existing system.
Field-proven Sensor Innovations
All of our sensors are engineered to be fast and reliable
with eld-proven performance in the harshest industrial
conditions possible. These include 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.
