Product Features
1. By utilizing imported high-performance, long-life (100000 hours), and high brightness light sources, coupled with narrowband filtering systems, the optical stability is extremely strong and not easily affected by various types of light interference, resulting in high precision and good stability of the instrument.
2. Large screen LCD Chinese display, Chinese menu operation, simple and intuitive.
3. The measurement data can be permanently saved, and in addition to the factory calibration curve, there is also a user-defined calibration curve for the working curve.
4. The main casing is made of ABS material after molding, which has good corrosion resistance.
5. Adopting a high-performance, low-power 16 bit microcontroller system with excellent performance.
6. Data power-off function protection.
7. Compliant with the national standard GBT 3286.2-2012 Chemical Analysis Methods for Limestone and Dolomite
