Instrument characteristics

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.

Both the measuring instrument and the digestion instrument are color touch screens with a user-friendly interface and display in both Chinese and English. Simple and time-saving operation. Dissolving colorimetric does not require changing the tube.

The digestion instrument has multi-point error free calibration, achieving zero error measurement of the set point, completely eliminating the errors caused by the nonlinearity of temperature sensors in common digestion instruments on the market.

The digestion instrument has a timed reminder and can be set to automatically shut down after digestion. The instrument has a secondary protection function. When the temperature of the digestion instrument exceeds 200 degrees, the instrument will cut off the power by itself to ensure the safety of the digestion process.

It can store 300 standard curves and 1000 measured values without losing them when powered off.

Can query curves, in addition to querying curve equations, it can also query the standard value and corresponding absorbance of each standard substance during calibration, as well as the calibration time and calibration personnel number, fully reproducing the state during calibration

Printing function: It can print single items or pages of test records.

USB interface, can be connected to a computer.

The instrument has a one click recovery function to prevent accidental loss of curves and data.

The instrument comes with a calibration function that allows for self calibration during operation, effectively eliminating drift errors caused by long-term use.
