What is it?
The Sensitron SMART 3G C2 is an advanced gas detector designed for industrial and marine applications, developed for continuous monitoring of toxic and flammable gases as well as oxygen levels. Thanks to its modular design and clear 4-digit display with magnetic pen interface, the device is easy to install, configure, and maintain.

How does it work?
The SMART 3G C2 detects gas concentrations using a wide range of interchangeable sensor modules. Alarm thresholds are set via the display and magnetic pen. When thresholds are exceeded, the system triggers visual alerts via a multicolour LED ring, audible alarms, and relay outputs. Communication with systems such as BMS or PLCs is enabled via 4–20 mA output and optionally RS‑485 Modbus. The detector performs continuous self-diagnosis to ensure reliability.

What problems does it solve?
In environments where gas leaks or oxygen deficiency pose serious risks—such as refineries, processing industries, water treatment facilities, or ships—the SMART 3G C2 provides a reliable and compliant solution. Its timely alarm at hazardous gas levels protects personnel, equipment, and the environment, while its powerful communication features allow easy integration into existing control systems.
