Fully-automatic heat-vaporization mercury measuring equipment
The model MA-2000 is intended for heat-vaporizing mercury present in a sample and then collecting it as a gold amalgam for measurement. This model does not require any wet pretreatment of samples, and hence can easily measure solid and liquid samples in as short a time as five minutes per sample. Both the control and data processing software are compatible with Windows, and labor-saving is achieved with the automatic sample changer.
