1. High accuracy and repeatability of wavelength: the monochromator adopts the digital control of imported high-precision stepping motor to effectively reduce the mechanical error and improve the wavelength accuracy. A new automatic wavelength calibration method ensures the repeatability and accuracy of wavelength.

2. 2. Dual optical system, full wavelength detection, can detect two wavelength signals at the same time;

3. 3. The new TTL deuterium lamp power supply can effectively prolong the life of deuterium lamp, and has the function of low energy prompt.

4. 4. The circulation pool is external, easy to clean and maintain; it can be analyzed, prepared and replaced, easy to enlarge the system. According to the customer's demand, the optical fiber circulation pool can also be selected, which meets the GMP requirements;

5. 5. Multi mode wavelength scanning: three scanning modes and a full set of time program functions can be provided;

6. 6. Signal output can be directly connected to computer through RS-232 or USB conversion interface, avoiding multiple conversion of signal, making performance more stable, reducing baseline noise and drift of detector, and improving detection sensitivity.

7. Friendly human-computer interface: 320x240 4.7 inch LCD, popular table interface design. Open source computer reverse control communication protocol is convenient for third-party software control.

8. Unique optical fiber flow cell, 316L or PEEK material is optional, meeting GMP certification requirements.
