• Easy to operate: color screen LCD display, Chinese interactive interface prompt operation, man-machine dialogue, strong operation logic;
• Split structure: the optical sensor unit is separated from the data processing and display unit, which is more hygienic, environmentally friendly and easy to operate;
• Measurement stability: the optical measurement system adopts special lens protection technology to ensure the long-term stable operation of the optical system;
• Accurate data: with online calibration function, accurate monitoring data, real-time display of lampblack emission concentration and benchmark emission;
• Measurement function: it can be expanded to measure the working condition parameters (dynamic pressure, static pressure, flue gas temperature, etc.) of flue gas system;
• Data storage: 45000 groups of data can be stored, and the historical data of three months can be saved;
• Wireless transmission: GPRS technology is adopted to automatically transmit data to environmental monitoring department;
• Automatic alarm: it can display the switch state alarm of lampblack purification device and fan, and automatically alarm the excessive emission of lampblack.

The on-line monitor of cooking fume is based on full flow optical principle to test the content of cooking fume. The instrument is designed and manufactured according to the GB 18483-2001 "cooking fume emission standard" and the "on-line monitoring system for cooking fume concentration" issued by China Environmental Association (Beijing) Certification Center on July 7, 2011. The key parts are all imported parts, which have the advantages of high measurement accuracy, good stability and long service life. They are the preferred products for the manufacturers of lampblack purification equipment, catering enterprises and environmental monitoring units.
