2. 用途：不僅適用于地表水、地下水、海水、生活用水和工業廢水等各種水體 及土壤中石油類（礦物油）、動植物油及總油含量的監測，同時也是煙氣(飲食行業油煙)含油量監測國 家標準*的儀器。
3. 工作原理：用*、四氯乙烯、S316、三氯三氟乙烷、氟利昂等萃取水中的油類物質，測定總萃取物，然后將萃取液用硅酸鎂進行吸附，脫除動植物油等生物之后，測定石油類。總萃取物和石油類的含量均有波數分別為3030cm-1 2960cm-1 2930cm-1譜帶處的吸光度進行計算。
特點
測油儀集光學、機械、電器一體化設計，采用鋁合金底座，穩定性好，能量大、光程長，無漂移，*的電路、光路設計使信噪比有了顯著的提高，能檢出淹沒在噪聲中的光電信號。
真正的三波數符合國標"HJ637-2012"，紅外分光光度法不需作標準曲線，只作一組校正系數，不用做空白對比，直接進行測量，減少了操作人員的工作量、節省了時間。
譜圖掃描實時跟蹤，可更直觀的觀察譜圖的走向及掃描的位置。
采用雙比色皿對比，更能有效的減少對測量結果的偏差。
真實測量，對檢測數據不造假。
功能強大，既能定量測量，也能定性分析，設有餐飲油煙測量菜單，直接顯示油煙測量結果。
儀器的外形美觀、大方，操作及其簡單、易學易懂。
10.2寸工業級觸摸顯示屏，屏幕大、清晰度高，中文菜單操作，顯示的內容更為豐富。
可脫離計算機獨立使用，也可連接計算機存儲、處理、傳輸數據。
儀器自帶打印功能，可根據用戶工作需要，實時打印測量結果，減少了操作人員的工作量及差錯率，更為方便的滿足了不同用戶的需求。

PCYY637 infrared photometric oil meter
Overview
1. Applicable standards: HJ637-2018
2. Uses: It is not only suitable for the monitoring of petroleum (mineral oil), animal and vegetable oil and total oil content in various water bodies and soils such as surface water, groundwater, sea water, domestic water and industrial wastewater, but also smoke (food industry soot) Instruments recommended by national standards for oil content monitoring.
3. Working principle: extract the oil in the water with carbon tetrachloride, tetrachloroethylene, S316, trichlorotrifluoroethane, freon, etc., and measure the total extract, then adsorb the extract with magnesium silicate. After the animals and other organisms such as vegetable oil, the petroleum is measured. The total extract and petroleum content were calculated by the absorbance at the bａnd of 3030 cm-1 2960 cm-1 2930 cm-1.
Features
The oil measuring instrument integrates optical, mechanical and electrical design, adopts aluminum alloy base, has good stability, large energy, long optical path and no drift. The unique circuit and optical path design make the signal-to-noise ratio significantly improved. A photoelectric signal that is submerged in noise.
The true three-wavenumber is in line with the national standard "HJ637-2012". The infrared spectrophotometry does not need to be a standard curve. It only makes a set of correction factors. It does not need to make a blank comparison and directly measures, reducing the workload of the operator and saving time.
Spectral scanning real-time tracking allows for a more intuitive view of the direction of the spectrum and the location of the scan.
By using double cuvette comparison, it is more effective to reduce the deviation of measurement results.
Real measurement, no false detection data.
Powerful, both quantitative and qualitative analysis, with a dedicated restaurant fume measurement menu, directly display soot measurement results.
The appearance of the instrument is beautiful and generous, and the operation is simple and easy to learn.
10.2-inch industrial-grade touch screen display, large screen, high definition, Chinese menu operation, display more content.
It can be used independently from the computer, or it can be connected to a computer to store, process, and transfer data.
The instrument comes with a printing function, which can print the measurement results in real time according to the users work needs, reducing the workload and error rate of the operator, and more convenient to meet the needs of different users.
