Product Introduction

HED-9000 typeIntelligent UV oil analyzerA precise and efficient oil measuring instrument has been developed based on the requirements of national environmental monitoring technical specifications, combined with the environmental pollution situation in China and the needs of various environmental monitoring departments HED-9000 typeIntelligent UV oil analyzerIt uses n-hexane extractant instead of the banned carbon tetrachloride extractant in infrared method, which meets the requirements of the new national standard "HJ970-2018 Determination of Petroleum in Water Quality by UV spectrophotometry" This product is easy to operate, has good precision, high sensitivity, and stable performance

Scope of Application

HED-9000 typeUV intelligent oil analyzerSuitable for the determination of petroleum in surface water, groundwater, and seawater;Intelligent UV oil analyzerWidely used in environmental monitoring systems, agricultural environmental monitoring, petrochemicals, universities, research institutes, sewage treatment plants, water conservancy and hydrology, waterworks, papermaking, pharmaceuticals, steel and other industries

Detection Principle

Under the condition of pH ≤ 2, the oil substances in the sample are extracted by n-hexane. The extract is dehydrated by anhydrous sodium sulfate and then adsorbed by magnesium silicate to remove polar substances such as animal and plant oils. The absorbance is measured in the ultraviolet region, and the petroleum content and absorbance value conform to Lambert Beer's law, thus quantitatively analyzing the petroleum content in water

Features

01) Equipped with a 7-inch color touch screen, easy to operate, and one click detection

02) The extraction agent used is n-hexane, which has a much lower impact on humans and the environment than the carbon tetrachloride used in infrared oil detectors

03) Equipped with scanning function, capable of self checking the purity of n-hexane

04) A single interface contains information such as detection time, detection items, absorbance, transmittance, wavelength value, concentration value, curve, etc

05) Built in 5 standard curves, can add and modify curves

06) UV light is used for detection, and the instrument automatically measures the absorbance and then calculates the concentration. The operation is simple and the results are accurate

07) Large capacity can store 1 million sets of data

08) The instrument has self checking function, automatic calibration of the instrument system, or error alarm function

09) With USB connection, data transfer function can be achieved
