Functional Features
The separation of the measuring instrument and the digestion instrument does not affect the stability of the optical system.
The measuring instrument is a cold light source and narrowband interferometric optical system with good optical stability.
● LCD large screen with Chinese display, easy and intuitive operation.
The digestion instrument has PID automatic temperature control and timing, with high accuracy.
Simple and time-saving operation, no need to change the tube for digestion and colorimetric analysis.
The digestion temperature and time can be infinitely set for other purposes.
It can save 10 standard curves and 500 measured values without losing them when powered off.
