Hydrocarbon Gas Detection and Alarm System

Hydrocarbon Gas Detection & Alarm System

The OKet® Hydrocarbon Gas Detection and Alarm System provides reliable detection of flammable hydrocarbon vapors in hazardous environments.

Available in wired and wireless versions, it is suitable for both new installations and retrofit projects in fuel stations and industrial sites.

Based on NDIR technology, the system delivers stable accuracy, fast alarm response, and long service life, ensuring early warning and effective gas risk prevention.

Why NDIR?

NDIR detection does not rely on chemical reactions, offering no sensor poisoning, no drift, and minimal maintenance, making it ideal for long-term fuel vapor monitoring.

Wired/Wireless Options

•Flexible selection of multiple configurations
