It is equipped with a scanning high-precision optical sensor, ensuring high sensitivity, high detection accuracy, and high repeatability accuracy. The instrument is configured with a four-wavelength cold light source, and each channel is equipped with 410nm, 520nm, 590nm, and 630nm wavelength light sources. It is equipped with an advanced optical path switching device, and the patented optical path switching function can realize up to 64 wavelengths. All detection items can be detected simultaneously in all channels. The light source brightness is automatically adjusted and calibrated, with intelligent constant current and voltage stabilization, and automatic light intensity calibration. There is no temperature drift of the light source during long-term continuous work.

4. User-Friendly Operation and Sample Management: The instrument has a built-in operation teaching video; users can quickly view the video by clicking the video module, which is convenient for use. The sample processing is simple and labor-saving, and the overall operation is fast, safe, and convenient. It has a variety of sample menu libraries, allowing flexible selection of test samples, and different detection channels can simultaneously detect different sample items. The instrument has a built-in powerful database, which allows users to directly select the sample name, detection index, inspection unit and other information on the instrument, and also can directly edit and input the sample name, detection index, inspection unit and other information on the instrument and save them into the sample database.

5. Security and Expandability: The instrument can be configured with an identity recognition function, which can be turned on by password or ID card swiping to prevent operation by non-staff. It has functions of re-calibration, locking, and restoring factory settings. The result judgment line can be modified, the reference value and calibration value can be saved, and data will not be lost when the power is off. It is compatible with all veterinary drug detection colloidal gold cards on the market, with no restrictions on the use of consumables, which greatly enhances the user experience. The detection items can be expanded, and the firmware can be upgraded.
