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.

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 save 100 standard curves and 10000 measured values each, without losing them when powered off.

LCD large screen LCD display, easy and intuitive operation.

Printing function: It can print test records immediately or query records for printing.

USB interface, can be connected to a computer.
