The Monicon Single Channel Gas Monitor is an innovative, cost effective, wall mounted unit. It is designed to operate in conjunction with the T100 toxic gas detector or the highly successful CGS500 combustible gas sensor to monitor a range of toxic gases, combustible gases and oxygen in a wide range of applications.
The Single Channel Gas Monitor is also compatible with a wide range of third party sensors and 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.
Simple to use and microprocessor controlled, the Single 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.
Monicon have pioneered a novel approach to significantly reduce false alarms by processing the sensor signal through an advanced analysis program in the microprocessor. Monicon's digital signal processing algorithms are an innovative approach to compensate for the undesirable effects of RFI, Humidity changes, EMI, pressure changes, vibration and electrical noise.
The microprocessor implements a comprehensive self-test routine, continually monitoring the system's performance and functionality. The self-test routine examines the integrity of the system's electronic circuitry, system software, sensor cabling, sensor signal, ancillary cabling etc. In the unlikely event of a fault, the digital display will indicate the nature of the condition in a user-friendly diagnostic mode.
The Monicon Single 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 mains power 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 Single Channel Gas Monitor offers a robust, easy to use, cost effective approach to providing an effective gas monitoring system where safety matters.
