Product details
■Product Overview:
SEM9880Online monitoring instrument for oil in waterIt is a new generation fully automatic online analyzer for oil in water. This product is a maintenance free online monitoring instrument launched by Shanghai Yizhan Environmental Protection Technology Co., Ltd. based on years of research on water quality analysis products. After passing through the pre-treatment device, the water sample and indicator are separately sent to the colorimetric cell and then irradiated with ultraviolet light to produce ultraviolet absorption. The instrument can directly measure the oil value in the water sample through photoelectric colorimetry.
■Measurement principle:
The online analyzer for oil (hydrocarbons) in water is designed specifically for measuring the concentration of oil (hydrocarbons) in water. The instrument uses ultraviolet fluorescence method to measure the concentration of oil molecules in water. Oil molecules are activated into an excited state under specific ultraviolet light irradiation, which is very unstable and quickly returns to the ground state; During the process of returning to the ground state, radiation fluorescence is generated, and the concentration of oil molecules in the water sample is directly proportional to the intensity of the emitted radiation fluorescence. The water sample is sent to the colorimetric cell after passing through the pre-treatment device, and the light source is parallel to the oil molecules in the colorimetric cell. The generated fluorescence is irradiated on the fluorescence sensor, and a precise filtering system is installed before the ultraviolet light emission and fluorescence sensor reception to control the emission wavelength of ultraviolet light and select the specific fluorescence wavelength that receives the scattered oil molecules. The received fluorescence intensity corresponds to the concentration of oil in the water sample to a certain extent. After the selection and control of the emission and reception wavelengths by the filtering system, this linear relationship can be made more clear.

System alarm and fault handling:
When the system encounters an alarm, the instrument stops running and maintains the process and state of the instrument alarm, and displays the specific alarm content in the lower left corner of the instrument LCD screen interface. Relevant personnel should analyze the causes of the alarm and take corresponding measures according to the handling methods provided in the table below. After processing, please select 'System Pause' for functional testing before continuing with instrument calibration and measurement.
