M22 Millennium II Dual Channel Transmitter

The M22 dual channel universal transmitter has been completely redesigned to include innovative features required by field engineers and operators, and can operate with rock solid performance even under the most extreme conditions. With the dual channel option, you can use a single transmitter

The M22 dual channel universal transmitter has been completely redesigned to include innovative features required by field engineers and operators, and can operate with rock solid performance even under the most extreme conditions. With the dual channel option, you can cover large areas with a single transmitter - mix and match, plug and play! No other platform can achieve this level of universality and outstanding performance.

Sensor exchange is convenient, and electrochemical, infrared, and catalytic combustion sensor technologies can be used. The Millennium II transmitter can automatically recognize any pre calibrated sensor connected and maintain uninterrupted digital signals between them, achieving extremely fast response speeds and sensor spacing distances exceeding 2000ft (600m).

The intuitive menu interface and non-invasive commands of Class 1 Zone 1 can be accessed through the included external magnets and ultra bright OLED graphic display screen. This OLED display is unparalleled in the market, and can be read clearly in dark or strong sunlight, hot or low temperature environments up to -55 ° C! Install our optional intrinsic safety HART on the right side of the transmitter through a handheld device ® The port adapter can implement built-in data logging and advanced diagnostic functions.

All of this means that our detection solution performs outstandingly in terms of performance, versatility, and efficiency. Only with the unique combination technology of Net Safety can we increase normal operating time, reduce energy consumption, and expand the safety range.

Millennium II Gas Detector - SC3 Combustible (LEL) Gas Detector - Zero Calibration Procedure

We need visual guidance for all steps to complete the zero calibration of the SX3 series combustible gas detection sensors (catalytic combustion and infrared) using the Net Safety Monitoring Millennium II transmitter. [2:21]

Universal transmitter

This transmitter can be connected to various toxic and/or flammable gas sensors. The sensor has been pre calibrated and can be easily connected to a transmitter that can instantly recognize newly connected sensors and automatically upload specific configuration files.

Single channel or multi-channel controller

No need to purchase other gas specific detectors. Use 1 to 2 sensors and mix and match SMART controllers and sensors according to the gas type.

Market leading warranty period

Infrared and catalytic combustion sensors -5-year warranty

Electrochemical sensor -2-year warranty

Transmitter and electronic components -3-year warranty

Global certification

FM certification performance, Class 1 Zone 1 explosion-proof certification CSA, ANSI-UL/ISA, ATEX, INMETRO, and GOST-R safety and technical standards - SIL2 By T Ü V S Ü D - ABS ship certification.

Minimum achievable power - widest input power range

The use of instrument cables with smaller diameters (which means lower installation costs and improved system stability) has increased the distance between sensors (+2000ft.). During the period of public voltage drop, serious situations may occur; The detector stops running or shuts down due to malfunctions, and the industry's lowest power consumption level makes it highly suitable for solar, TEG, and turbine driven applications.

quick response

Sensors and transmitters communicate continuously through digital means, providing you with reliable, stable, and precise protection, with first-class response speed and the fastest response to H2S on the market!

Mature sensor technology

All of our sensors are designed with proven practices, fast and reliable. This includes a wide range of fast response electrochemical toxic gas sensors; The use of SensorGuard's non-toxic catalytic combustion technology can significantly extend the lifespan of sensors (see below); Infrared sensor technology adopts a dual beam design without mirrors (which may be contaminated [atomized] or misaligned).

The proprietary SensorGuard system on catalytic combustion sensors

After conducting gas leak detection/alarm events, if there is still high concentration gas in the area, our advanced microprocessor automatically terminates the gas flow to the sensor to prevent over saturation (100% LEL). This can prevent the sensor from burning out prematurely and significantly extend its service life. This unique feature allows Net Safety to provide a market leading 5-year warranty for all of our catalytic combustion sensors.

Excellent reliability

The Net Safety gas detection solution has been validated in the harshest possible conditions and has always been the preferred choice for operators due to its ease of use, reliable performance, and high flexibility.

Bright OLED display screen

The only detector on the market with a full image OLED display that is easy to read under all ambient lighting conditions, capable of operating at temperatures as low as -55 ° C!

Simulation, relay, Modbus 485 RTU, and HART communication protocols

The enhanced communication function allows the detector to seamlessly work with external security devices.

Easy to use menu

Whether you want to disable the sensor or set the display language to English, French, Portuguese, or Spanish, the full text menu instructions make installation, operation, and instructions very simple. No manual required!

Event Log

Calibration intervals, low/high gas alarms, and faults will be time and date stamped and stored in non-volatile memory. Record up to 980 consecutive events.
