DA7250 is an advanced near-infrared analyzer with faster analysis speed and more user-friendly operation than any previous near-infrared instrument

Simplicity and higher accuracy. It is the second-generation diode array analyzer from Swedish company Borton Instruments, based on our years of experience

There have been many updates and improvements made. DA7250 adopts an optical design combining fixed holographic grating and diode array, which processes information of all wavelengths in parallel and can continuously collect spectral data in the near-infrared region. The optical system is completely fixed. Suitable for rapid non-destructive analysis of some physical and chemical properties of whole, powder, liquid, paste and other samples, such as moisture, protein, fat, starch, essential amino acids, acid value, iodine value, dry matter, hardness and particle size.



Features and advantages

• Equipped with the most stable optical system, unique fixed holographic grating beam splitting and

Indium gallium arsenide diode array detection technology (electrically cooled constant temperature) full spectrum simultaneous scanning without wavelength drift

• Automatic baseline correction, optical substrate reference plate, system automatically compensates for the influence of ambient light

Convenient sample replacement and suitable for detecting various forms of samples. Near infrared diffuse reflectance technology is used for powder and paste samples, and near-infrared transmittance reflectance technology is used for liquid samples

• Large detection area, while using a rotating sample disk for scanning, making the detection of uneven samples more accurate

The data spectrum collection rate is 100 times per second, with fast measurement speed and high sensitivity

• Sample size 1-300 grams, providing sample trays of different sizes to meet different requirements

The instrument has self diagnostic function and automatic fault prompt function

Using halogen tungsten lamp and xenon lamp light sources, dual beam simultaneous detection for higher accuracy

The light source lamp adopts a unique long-life design, with no other consumables and low long-term use costs
