Product Description
The New Cosmos Electric NV-100C is a single-point combustible gas detection and alarm system designed for continuous monitoring of combustible gas leakage in industrial environments. It uses catalytic combustion on a platinum filament as its detection principle and displays gas concentration on an LCD bar graph meter with backlight. The unit is housed in an earthquake-resistant, slim plastic molded case and can be wall-hung or panel-embedded, making it suitable for petrochemical, semiconductor, and steel industry applications.
