Instrument features:

1. It can detect 8 heavy metal pollution indicators including hexavalent chromium, total chromium, cadmium, iron, zinc, copper, nickel, and manganese, all of which can achieve direct concentration reading

2. The instrument is equipped with multiple preset standard curves, and the correct curve is automatically matched when the user selects the detection indicator, without the need for manual switching

3. Adopting a 7-inch high-resolution true color touch screen, the user-friendly and concise menu design makes operation more time-saving. A single interface contains detailed information such as detection time, detection items, absorbance, transmittance, concentration values, curves, etc

4. The instrument performs control system self-test, detector self-test, energy calibration, wavelength automatic calibration, and deviation self repair every time it is turned on, ensuring the accuracy of wavelength and the reliability of data

5. It has a large storage space that can store 30000 sets of detailed detection data, making it easy for users to view, count, or print in the future

6. The instrument is equipped with 200 standard curve storage locations, supporting automatic curve calibration and automatic saving of calibration curves. It also supports users to establish extended detection projects, and user curve data and self built project information can be saved in case of power failure

7. The instrument has the function of automatically creating regression curves, allowing users to directly expand new detection items without manual calculation. It can support up to 10 point fitting, and the fitted curve can be saved for a long time for easy future use

8. The instrument comes with a dedicated embedded printer, which integrates sample detection and data printing, and can print real-time and historical data anytime and anywhere

9. The instrument has a dedicated communication interface and is equipped with testing expert software, which facilitates users to transmit data to a computer for summarization and mathematical statistics

10. Wide colorimetric cell design, capable of accommodating various specifications of colorimetric dishes ranging from 5 to 30mm, flexibly matching multiple experimental schemes

11. Equipped with professional improved semi prefabricated reagents, which can be used multiple times in one configuration, greatly reducing customer workload and effectively ensuring the accuracy of detection data
