Product Introduction
The HG-902 portable mercury analyzer is a portable mercury detection instrument for samples such as soil, water, air, and exhaust gas. The instrument is compact and easy to carry, mainly used for determining mercury content by cold atomic absorption method, and can also be used as a laboratory instrument. It measures mercury content in drinking water, natural water, and wastewater using the "cold vapor" method, without requiring pre-digestion of water samples. It can directly monitor mercury content in the atmosphere using the enrichment method, suitable for environmental soil, gas, and water quality mercury monitoring. It is also applicable for mercury monitoring in the atmosphere of production workshops (such as fluorescent lamp factories, energy-saving lamp factories, PVC factories) that contain mercury or volatile impurities. It is also used for mercury vapor sample analysis in geological, petroleum, and seismic systems for outdoor soil gas. Measurement data can be displayed on an LCD screen and saved in text format in the main unit, allowing connection to a computer for data adjustment at any time.
