Features
Using a new single-chip microcomputer system, it has strong functions, small size and easy maintenance.
Use flame-retardant, insulating all-plastic shell, exquisite shape design, easy operation, high safety factor.
True 4-digit LCD display, large measurement range and high calculation accuracy.
Membrane keyboard, good hand feeling, dustproof, waterproof and easy to clean.
Professional optical system design, sealed grating monochromator, scientific anti-mildew technology, stray light elimination technology, significantly improve service life, stray light, stability, and photometric accuracy indicators.
The lens is used to condense the light to prevent the energy of the reflector from plummeting after being ablated for a long time.
Special precision lamp holder, you can replace the tungsten halogen lamp by yourself without having to adjust the optical path again.
Automatic adjustment of 0%, automatic adjustment of 100% and absorbance OA.
