Product Features


Imported high-performance, long-life (100000 hours), high brightness light source from the United States, equipped with a highly stable optical system, with good accuracy and repeatability.

The digestion instrument adopts a 3.5-inch color touch screen with a resolution of 320x240 and displays in both Chinese and English.

Simple and time-saving operation. Dissolving colorimetric does not require changing the tube.

With multi-point error free calibration, zero error measurement of the set point is achieved, completely eliminating the errors caused by the nonlinearity of temperature sensors in common digesters 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 10 working curves and 999 historical records without losing them during power outages.

Equipped with a USB interface, data can be transferred to a computer.

Equipped with printing function, it can immediately print or query test records for printing.
