LY-3040 Direct-Reading Oil Fume Detector is a portable, high-precision integrated measuring instrument for on-site rapid detection of oil fume emission concentration. Based on the laser scattering method, it realizes real-time direct reading of oil fume data without complex manual sampling and analysis. The instrument can simultaneously measure flue gas temperature, dynamic pressure, static pressure, moisture content and flow velocity, providing complete working condition parameters for evaluating organized oil fume emissions. With stable performance, simple operation and compact structure, it is widely applied in environmental supervision, catering industry, industrial flue gas monitoring and third-party testing fields.
The instrument uses the laser scattering method to realize real-time online monitoring of oil fume concentration with high accuracy and good data repeatability. It supports automatic measurement and avoids complicated laboratory analysis, greatly improving on-site detection efficiency.
The sampling probe is heated along its entire length to effectively reduce oil fume condensation and adsorption. The main gas path adopts a PTFE tube which is easy to replace and minimizes gas adsorption, ensuring measurement stability.
Equipped with a high-resolution touch screen for intuitive operation and large-capacity data storage (up to 8000 files). Built-in rechargeable lithium battery supports AC/DC power supply. It is matched with a Bluetooth printer for wireless printing and a USB port for data export and software upgrade.
Supports single and continuous sampling modes with customizable cycle parameters. The modular oil fume sensor, replaceable Pitot tube, detachable filter observation window and dedicated protective case make field use and daily maintenance more convenient. The built-in electronic tag supports intelligent instrument management.
The LY-3040 Direct-Reading Oil Fume Detector is designed and manufactured in full compliance with global stationary pollution source emission monitoring standards and catering industry oil fume control specifications. It fully aligns with international and regional requirements for oil fume concentration measurement, flue gas parameter detection, and organized emission assessment. The instrument meets the testing protocols for catering fume monitoring, environmental law enforcement inspection, and third-party compliance verification, and supports standard-compliant field detection for restaurants, canteens, industrial kitchens, and environmental supervision authorities worldwide.
