Instrument features

1. The digestion instrument is separated from the analyzer, which does not affect the measurement accuracy. The temperature PID automatically controls the temperature and timing.

2. High-performance ultra-low power 16-bit single-chip microcomputer, the instrument standby time can reach more than 6 months.

3. Time-saving operation.

4. Cold light source, narrow-band interference optical system, good optical stability.

5. Data power-off protection function.

6. Each test can save 30 standard curves and 199 measured values (including the measured values of the year, month, day, hour, minute and second with time stamp, absorbance and transmittance)

7. With USB port, you can connect to the computer for record reading or print the stored data.

8. The mainframe casing is molded with ABS material and IP65 design, which is waterproof and dustproof.
