UT334L Natural Gas Detector — Intelligent Combustible Gas Leak Sensor with Curve Periodogram Display

The UT334L is a highly intelligent gas leak detector built on advanced large-scale integrated circuit technology and proprietary digital-analog hybrid communication. Designed to detect combustible gases through a free diffusion method, this sensor delivers fast, repeatable readings with a reliable performance that meets industrial safety monitoring demands. Its rugged shell is crafted from high-strength engineering plastic to provide a comfortable grip and durable operation in challenging environments.

Why UT334L Stands Out

• Curve periodogram measurement display on a vivid color screen lets you visualize gas concentration trends over time, enabling proactive safety decisions.
• High-sensitivity gas sensor with fast response ensures rapid detection of even trace amounts of combustible gas.
• Triple alarm system: audible, visual (alarm light), and vibration to ensure alerts are noticed in noisy or visually obstructed environments.
• Alarm point settings and dedicated alarm records help you tailor thresholds and review event history for compliance and audits.
• Snake-shaped hoses (350 mm) simplify access to pipelines and narrow spaces, enhancing versatility in complex facilities.
• Integrated LED flashlight supports detection work in dark or confined areas.

Display, Interface, and Usability

Equipped with a color screen and bilingual support (Chinese/English), the UT334L presents readings clearly and offers an intuitive user experience suitable for diverse teams. The diffusion sampling method provides reliable in-situ measurements, backed by precise resolving power across a wide range of concentrations.

Power, Reliability, and Maintenance

• Powering this unit is a compact 3.7V, 2000 mAh lithium battery, designed for extended field use without frequent recharging.
• The device is built to be easy to operate and maintain, aligning with the reliability requirements of industrial safety equipment.

Operating Conditions and Safety

• Working temperature range: -10 to 50°C
