特點
測油儀集光學(xué)、機械、電器一體化設(shè)計，采用鋁合金底座，穩(wěn)定性好，能量大、光程長，無漂移，獨特的電路、光路設(shè)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(shù)符合國標(biāo)"HJ637-2012"，紅外分光光度法不需作標(biāo)準(zhǔn)曲線，只作一組校正系數(shù)，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(jié)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(jié)果的偏差。
真實測量，對檢測數(shù)據(jù)不造假。
功能，既能定量測量，也能定性分析，設(shè)有專用餐飲油煙測量菜單，直接顯示油煙測量結(jié)果。
儀器的外形美觀、大方，操作及其簡單、易學(xué)易懂。
10.2寸工業(yè)級觸摸顯示屏，屏幕大、清晰度高，中文菜單操作，顯示的內(nèi)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(shù)據(jù)。
儀器自帶打印功能，可根據(jù)用戶工作需要，實時打印測量結(jié)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.
