NIR-7000 spectrometer is a double/dual beam spectrophotometer with continuous scanning in UV Vis NIR band. It can be used in building glass energy-saving detection, building engineering quality testing, automobile glass testing, material science research, scientific research in Colleges and universities, etc. The samples that can be detected are: ordinary flat glass, electro float glass, laminated glass, ion-plated glass, sputtering coated glass, Low-E glass, automobile safety film, etc.

The double beam optical system design reduces the background interference and improves the accuracy and accuracy of the test.

The receiver of the instrument ensures the high performance and stability of the instrument.

The control of the instrument (such as grating conversion, filter conversion, receiver conversion, wavelength scanning, etc.) is all controlled by the computer, and the interface is USB2.0.

The connection of the instrument is simple, which greatly improves the communication speed.

Zf720-20 glass integrated optical test system software can be selected to automatically detect the visible light transmittance, direct sunlight transmittance, direct sunlight reflectance and other related parameters of building glass.

The total solar transmittance and the shielding coefficient of various window glass components to solar radiation heat can be obtained by using the glass hemispherical emissivity detector.

Special sample test accessories can be selected.

The software can set the import function to import text format data.

Real time measurement of sample data and export of test result data.

The software can run under WinXP and win7 system.
