Zetian - Model PZ2200 -Portable Zeeman Cold Atomic Absorption Mercury Analyzer
The PZ2200 is a lightweight, high-precision mercury analyzer that utilizes high-frequency Zeeman background correction technology (ZAAS-HFM). Based on the principle of mercury vapor absorption at the 254?nm resonance line, it continuously draws gas samples into the detection unit using an extractive sampling system and a maintenance-free diaphragm pump. By measuring the attenuation of UV light, it accurately determines mercury concentration in ambient air at levels above 0.2?μg/m³. Designed for indoor and outdoor continuous monitoring, it’s widely used in industrial hygiene, ecological surveillance, process control, and scientific research.
