The Jerome 431-X Mercury Vapor Analyzer uses a gold film sensor for the detection and accurate measurement of toxic mercury vapor in the air. A portable hand-held unit, the Jerome 431-X can easily be carried to locations of mercury concerns. Simple, push-button operation allows users to measure mercury levels in just seconds. The range of the 431-X is from 0.000 to 0.999 mg/m3 Hg. The gold film sensor is inherently stable and selective to mercury, eliminating interference common to ultraviolet analyzers, such as water vapor and hydrocarbons. The 431-X includes features not available in older Jerome models. When attached to either a data logger or computer, the analyzer automatically regenerates the sensor when it becomes saturated and then resumes sampling. An improved film regeneration circuit makes the sensor last even longer.
