Common Features

  1. The holographic blazed grating monochromator has the advantages of high wavelength accuracy, good monochromaticity and low stray light.
  2. 7-inch multi color touch-screen, good human-computer interface. ( 752N Plus and 722N )
  3. Linear regression method and coefficient method are added to the concentration test method.
  4. USB interface is added, and large capacity memory can store 30 concentration curves.
  5. Adopt microcomputer measurement system, with high conversion accuracy of T-A, automatic adjustment of
    0% T and 100% T, concentration factor setting and concentration direct reading.
  6. High accuracy, Good Reproducibility and Stability of Measurement Readings.
  7. Automatic light gate technology, No need blackbody, to protect the photoelectric sensor.
