A specialist range of Hazardous Area Indicators designed for use in explosive or potentially volatile environments. Certified to ATEX and IECEx standards, our indicators are engineered to display process measurements such as 4–20mA loop currents safely and clearly within hazardous areas. They are suitable for a wide range of industrial applications including oil and gas, chemical processing, marine, and pharmaceutical sectors.

Our intrinsically safe and flameproof indicators are available in both field and panel mounting formats, and include loop-powered displays and bar graph indicators for intuitive readouts. With options including Type nA non-sparking models and robust enclosures designed for Zone 1 and Zone 2 areas, these products ensure operators can safely monitor system data even in high-risk settings.

These hazardous area indicators are built for reliability and ease of integration with other instrumentation, including our own float switches, level sensors, and Zener barriers. Whether you require a single-channel indicator or a custom solution, we provide high-specification products supported by knowledgeable technical guidance and ongoing customer support.

Where are hazardous area indicators used?
Hazardous area indicators are used in industrial environments where operators need clear status, level or process information in potentially explosive atmospheres. Typical applications include chemical plants, fuel handling areas and process control systems.
Why do indicators need hazardous area certification?
Indicators used in hazardous areas need suitable certification because electrical equipment can create ignition risks through sparks, heat or faults. Certified indicators are designed to operate safely in the specified hazardous environment.
Can hazardous area indicators be used with ATEX sensors?
Hazardous area indicators can be used alongside ATEX sensors where the full system is designed correctly for the application. The indicator, sensor, wiring and any associated safety equipment must all be suitable for the hazardous area classification.
