Product Features
1. The separation of the measuring instrument and the digestion instrument does not affect the stability of the optical system.
2. The measuring instrument is a cold light source and narrowband interferometric optical system with good optical stability. The calibration light intensity can be adjusted to 16 levels and set arbitrarily, which can effectively solve the problem of measurement range expansion caused by signal strength.
3. The host and digestion instrument have a color touch screen display in both Chinese and English, with a user-friendly interface and an operation guide to provide instructions for various functional operations.
4. The curve can be queried, in addition to querying the curve equation, 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.
5. It has a one click recovery function, which can achieve one click recovery when the factory curve and user curve data records are lost due to accidents
6. 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.
7. 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.
8. In addition to a maximum of 250 factory curves, users can add 3500 curves themselves, calibrate them, and store them in the instrument.
9. Store up to 100000 records (including parameter names, concentrations, units, detection times, operator numbers, etc.).
10. It has printing function: it can print the test records immediately or query the records for printing.
11. USB interface, can be connected to a computer.
