FAQ

1. Q: What is the core detection principle of the gutter oil detector?
   A: The mainstream technology is fluorescence spectrophotometry, where benzo [a] pyrene emits fluorescence under specific wavelength ultraviolet light irradiation. The instrument captures the signal through a photomultiplier tube and calculates the concentration. Yuntang Technology adopts four wavelength cold light source technology, with a detection limit as low as 0.1 μ g/kg, far superior to the national standard of 10 μ g/kg limit.

2. Q: Can the test results be directly used as the basis for administrative penalties?
   A: The rapid inspection results are only used for initial screening and risk warning, and administrative penalties shall be based on the laboratory's statutory inspection report. Yuntang Technology equipment is often selected as a reference for fast inspection due to its high accuracy, but its data still needs to be confirmed later.

3. Q: How stable is the equipment in high temperature environments?
   A: Hengmei manufacturing equipment adopts IP67 waterproof rating and wide temperature range design, which can operate stably in environments ranging from -20 ℃ to 50 ℃. The 900mAh lithium battery supports 30 hours of continuous operation and is suitable for high-temperature detection scenarios of frying oil.

4. Q: How to reduce long-term usage costs?
   A: Blue Rainbow Optoelectronics uses open algorithm design to be compatible with mainstream brand gold label cards in the market, reducing consumables costs by 40% compared to the industry average; Although Yuntang Technology's single consumable cost is about 15 yuan, the long-term cost is lower when the daily testing volume exceeds 10 samples.
