Grain and Oil Heavy Metal Detector - UX-820, UX820S PLUS

I. Description of Grain and Oil Heavy Metal Detector UX-820, UX820S PLUS

The UX-820 series XRF grain and oil heavy metal rapid detector is an X-ray fluorescence spectrometer for rapid heavy metal detection developed by Shenzhen Huawei Measurement Technology Development Co., Ltd. It is mainly used for rapid, non-destructive detection of toxic and harmful heavy metal elements such as cadmium (Cd) in crops like rice, wheat, corn, soybeans, and tea. No chemical pretreatment of samples is required; direct testing is possible. Samples can be quickly screened within minutes.

> Mainly for rapid, non-destructive detection of toxic and harmful heavy metal elements in crops such as rice, wheat, corn, soybeans, and tea. No chemical pretreatment of samples is required; direct testing is possible.

> The instrument is easy to operate, no professional requirements, just operate the computer to quickly get started. Uses a high-power, high-voltage X-ray tube to fully excite harmful elements, enabling the detector to achieve count rates, greatly improving detection limits and testing accuracy.

> Screening of Cd element limit value of 0.2ppm in rice can be completed within 200 seconds (3.3 minutes), and precise quantification within 1500 seconds (25 minutes).

> Has the National Grain Bureau Standard Quality Center's 'National Standard Applicability Verification'

> The software features user-friendly red, yellow, and green lights (red for exceeding limits, green for environmentally friendly, yellow for critical values requiring further quantitative testing) for result judgment, making test results clear at a glance and greatly reducing operator testing requirements.
