Features
Ultra-wide wavelength range 360-780nm
The wavelength range of the instrument is 360-780nm, which is higher than the spectral range of the human eye, extending the measurement range.
More than 30 chroma indicators
Instrument built-in platinum cobalt, Gardner, Saybolt, Chinese Pharmacopoeia, US pharmacopoeia, European pharmacopoeia chroma and other latest indicators, products are suitable for liquid chemicals, coatings, pharmaceuticals, cosmetics, petroleum, industrial oil and other fields.
Intelligent zero calibration technology is used to ensure data stability of 0.01
With intelligent zero calibration technology, the measurement results are stable to 0.01 repeatability even in the case of environmental changes.
Minimum sample request reduced to 1ml
With a more sophisticated optical design and precise control of the direction of light transmission, the minimum liquid request is reduced to 1ml, 34% less than the previous generation, saving customers expensive samples. Compatible spectrophotometer cutlery, no additional purchase or custom cutlery required.
The PTC heating module produces a constant temperature of up to 90°C
Suitable for measuring easily solidified samples such as fat and wax, it can be heated up to 90°C and maintained at temperature, so that the sample can be tested in a liquid state
Support OTA online upgrade to update chroma indicators and new functions at any time
Instrument support online update software function, online add measurement indicators, users can upgrade automatically obtain.
