Vanta analyzer is an important tool for screening soil and other materials to detect heavy metals in pollution. The embedded GPS function can combine the detection results with their corresponding GPS coordinates, enabling the analyzer to trace samples back to the field. The Vanta analyzer can conveniently transmit GPS data and sample data to GIS via Wi Fi to create a mapping map of contaminated metals. This analyzer can quickly obtain decision-making results in site characterization, environmental assessment, property evaluation, and pollutant tracking.
