The Monicon 4 Channel Gas Monitor is an innovative, cost effective, wall mounted unit. It is
designed to operate in conjunction with the T100 toxic gas detector and the highly successful CGS500
combustible gas sensor to monitor a range of toxicgases, combustible gases and oxygen in a wide
range of applications.


The 4 Channel Gas Monitor is also compatible with a wide range of third party 4-20mA transmitters
including temperature probes. The gas concentration is indicated on a 4-digit, 7-segment
display while another 2-character alphanumeric display indicates instrument status. A third display
indicates the active channel.


Simple to use and microprocessor controlled, the 4 Channel Gas Monitor is menu assisted and fully user
programmable for alarm setpoints, relay options, range, sensor type, gas type and many other
parameters in a user friendly manner offering unique flexibility and control over the system.
The Monicon 4 Channel Gas Monitor has a built in battery trickle charger circuit and an optional
12V, 1.2AH rechargeable battery (sealed lead-acid type) may be fitted inside the enclosure to ensure
uninterrupted operation in the event of a mainspower failure.


Careful product design and rigorous product testing combined with a stringent ISO9002 quality
assurance program at Monicon’s state-of-the-art manufacturing facility ensure ultimate reliability.
The Monicon 4 Channel Gas Monitor offers a robust, easy to use, cost effective approach to providing
an effective gas monitoring system where safety matters.
