• Ultrasonic gas leak detector designed to detect high-pressure gas leaks by sensing ultrasonic sound.
• Suitable for hazardous and industrial environments.
• Detects gas leaks at the source before gas reaches conventional detectors.
• Unaffected by wind, gas dispersion, or weather conditions.
• Typical detection radius up to 20m (65 ft).
• Ideal for outdoor and well-ventilated areas where traditional gas detectors may be less effective.

Key Features

• Normal Mode provides wide-angle coverage for low-noise environments.
• Focus Mode uses advanced algorithms to reduce background noise interference.
• Intelligent noise filtering helps minimize false alarms.
• Bluetooth connectivity for wireless configuration and commissioning.
• Mobile app support for setup and diagnostics.
• Ground-level testing capability using a handheld test unit.
• No calibration required throughout operation.
• Solid-state sensor design with no moving parts.
• Built-in diagnostics and operational event logging.

Coverage & Detection

• Field of Coverage: ±90° solid angle from on-axis to 6dB down.
• Optimized for monitoring high-pressure gas leaks.
• Suitable for open and ventilated environments.
• Works alongside point gas detectors and open-path gas detectors.

Outputs & Communication

• 4-20 mA analogue output.
• HART communication.
• Modbus RTU RS485.
• Relay outputs.
