Food Heavy Metal Analyzer

Food Heavy Metal Analyzer

YANG 700F food heavy metal rapid analyzer is an XRF analytical instrument specially launched in the field of food security, used for rapid detection of cadmium, lead, mercury and other heavy metal elements in food. Its integration of LANScientific years of XRF research and development technology, crystal grating spectroscopic technology and basic parameter method and a number of high-end technologies, with small and portable, simple operation, fast and accurate advantages, can quickly improve the efficiency of on-site detection, escort for food security.



Waterproof and dustproof box (IP 67 waterproof and dustproof grade) all-in-one machine design, portable test platform, so that the field detection and laboratory analysis in one, one-button test, simple operation, automatic detection, no correction, free laboratory/field scientific research.


Specially developed for quick on-site analysis, the instrument can be fog-proof, dust-proof, shock-proof, can adapt to the harsh environment.

Heat dissipation

The instrument is equipped with a special two-way ventilation heat dissipation device to improve the heat dissipation performance of the instrument.


With professional multiple protective radiation treatment (sample chamber radiation shielding measures, safety linkage lock device), no radiation leakage in all directions of the instrument during measurement.

Cloud service

The device is equipped with a mobile application service that can be controlled synchronously. The mobile application service can operate data, labels and other information. Transmission and management, easily realize system data docking and sharing.

Data printing

Equipped with portable Bluetooth printer, the data can be output in Excel and PDF format, and users can create customized reports.

Sampling system

The equipment adopts the sample side injection detection method (the plane of detector beryllium window is perpendicular to gravity direction) to reduce the risk of detector beryllium window being damaged by grain, small particles and detector surface contamination.

Application scenario


Food reserves and circulation


Grain production link


Government Agency Regulation


Food safety certification
