NV-120 Series Single Point Gas Detection System


NV-120 Series Single Point Gas Detection System

The NV-120 Series is a full-featured, modular and multi-gas detection system. The panel is comprised of modular Indicator and Alarm units that can be individually replaced if required. The panel itself comes in wall mounted and panel mounted design depending on the number of detection channels required.

The indicator units have a direct reading LCD scale and dual alarm levels. They also supply power to their respective detector heads.
