-Fundamental principal

When a monochromatic light goes through the tested solution, its energy will be absorbed. The absorbed degree of the light intensity is proportional to concentration of the testing substance and the proportion conforms to the Lambert Beer’s law: A = log (1/T) = log (10/1) = a*b*C


-Products can meet the following standards:

■Meet the national standards: “GB/T16488-1996 infrared spectrophotometry of water quality petroleum and animal and plant oil”

■Meet the national standards: “GB3838-2002 surface water environment quality standard”

■Meet the national standards: “GB18483-2001 emission standard of cooking fume”

■Meet the national standards: “GB18918-2002 draining standard of pollutant in municipal sewage treatment plant”


-Applications

The equipment is mainly used the oil measurement in surface water, groundwater, the amount of industrial waste water, and it can also be used for the oil measurement in flue gas of restaurant industry and solid; this instrument is the professional instrument to measure the oil content in the water, gas, solid.


-High accuracy: every time, the measurement error is not more than ±2% (40 mg/L)

-The baseline drift is less than 0.005 AU / 60 min

-Electric light source modulation can improve equipment reliability

-Zero automatic adjustment can automatically adjust full-scale value of device

-Instrument uses RS232 or USB2.0 interface which is convenient to connect with computer

-It has the functions of mathematical statistics, spectrogram display, storage, printing, etc.

-It has the function of measuring instrument calibration coefficient

-It has functions of non-dispersive measurement results of direct reading, which don’t need to conversion

-It can test purity of carbon tetrachloride

-It can use the S-316, tetrachloroethylene, trichlorotrifluoroethane and other non-carbon chloride organic solvent as extracting agent
