Features
1. High performance, long life (100000 hours), high brightness light source imported from the United States,
2. With high stability optical system, it has good precision and repeatability.
3. The digester adopts a 3.5-inch color touch screen with a resolution of 320x240, which is displayed in Chinese and English. Simple and time-saving operation. The digestion colorimetry does not need to be changed.
4. With multi-point error free calibration, the zero error measurement of the set point is realized, which completely eliminates the error caused by the nonlinearity of the common digester in the market.
5. The digester has the function of timing reminder, which can automatically shutdown after digestion, and the instrument has the function of secondary protection. When the temperature of the digester exceeds 200 ℃, the instrument will cut off the power supply by itself to ensure the safety of the digestion process.
6. It can store 10 working curves and 999 historical records, data will not lose even when power is cut off.
7. With USB interface, data can be transferred to computer.
8. With printing function: you can print the measurement results immediately, or query and print records in the future. (TN-2A)
