Shanghai Lei Magnetic Portable Hexavalent Chromium Detector DGB-404F
Price:¥3200

SJB-801 The anode dissolution voltammetry principle detection can be used for the detection of six metal ions, including lead, cadmium, zinc, arsenic, copper and mercury, and has a detection limit and detection sensitivity similar to large instruments such as atomic absorption. The instrument has novel design, small size, simple operation and high intelligence. Portable inspection box design, convenient for rapid on-site inspection applications. This instrument can be widely used in environmental testing, social security and scientific research fields, and has broad application value and broad market prospects.
