This gas detector works on the FID principle and is built for monitoring VOCs fugitive emissions. It quickly and accurately pinpoints leaks at pipe valves, discharge ports and enclosed facility systems, so teams can carry out repairs in good time and keep equipment and production running without interruption. It also supports environmental agencies in strengthening the monitoring and management of VOCs fugitive emissions from enterprises. The instrument holds an explosion-proof certificate issued by the authority department, which makes it safe to use and operate in environments that call for explosion-proof equipment.
The LY-3033 Portable THC Analyzer FID is a professional, field-ready gas detection instrument based on the Flame Ionization Detector (FID) principle, optimized for high-precision VOCs fugitive emission monitoring and leak localization. Designed for industrial users and environmental regulatory agencies, this FID VOCs detector quickly and accurately identifies VOC leaks across pipeline valves, discharge ports and enclosed facility systems. This supports proactive maintenance, uninterrupted industrial operation and strict environmental compliance management. An optional PID detection configuration lets it adapt flexibly to different on-site monitoring needs.
Explosion-Proof Safety for Hazardous Industrial Environments :
This explosion-proof VOCs analyzer carries authoritative explosion-proof certification, allowing safe and compliant operation in high-risk explosive atmospheres. This is essential for petrochemical and refining facilities.
High-Precision Dual-Detection System :
It is equipped with a high-sensitivity, multi-range FID detector and an optional PID module. The detection limit is as low as 0.5 ppm, and the response time is under 3.5 s to reach 90% of the final reading, so leaks are captured accurately in real time.
Portable & Intuitive Operation :
The fully molded, lightweight body (under 3.1 kg) can be carried over the shoulder or diagonally with the included strap. The explosion-proof display controller offers wireless control for simple one-handed operation in complex field environments.
Intelligent System & Self-Diagnosis :
A built-in full self-test function automatically checks the instrument status and gives fault prompts to simplify maintenance. The analyzer also integrates with the optional LDAR (leak detection and repair) data platform, enabling full-process, systematic management of detection workflows.
The LY-3033 Portable THC Analyzer FID complies with the latest environmental monitoring standards and regulations issued by the Ministry of Ecology and Environment of China, as well as relevant international standards. It has obtained the China Environmental Protection Product Certification (CPA) and authoritative explosion-proof certification, which supports data validity and legal compliance for enterprise environmental reporting and regulatory enforcement.
