Brookfield AMETEK - Measurement and analysis of toxic gases (Hg, H2S)
For over 85 years, Brookfield AMETEK has been the global benchmark for viscosity measurement, texture, moisture and toxic gas analysis instruments (mercury, hydrogen sulfide at very low concentrations), making their instruments ideal for applications in a wide range of industries. They have centers of excellence in the USA, Germany, China and India, and a network of qualified representatives and dealers. It's no wonder that research laboratories, quality control and production environments rely on Brookfield AMETEK instruments for their reliability and accuracy.

Jerome, low concentration mercury (Hg) and hydrogen sulfide (H2S) vapor analyzers
Originating in Jerome, Arizona, the Jerome® line of mercury and hydrogen sulfide analyzers uses proprietary gold-film sensor technology to detect low levels of mercury and H2S. Since then, it has evolved, now offering portable and fixed solutions that use gold-film sensor technology as well as an advanced atomic fluorescence mercury vapor analyzer.
Mercury vapor detection and analysis
Mercury has long been used in products such as dental amalgams, thermometers and fluorescent bulbs. However, its increasing toxicity has led to its gradual phasing out, notably because of the risks associated with inhaling its vapors. These are particularly dangerous, as they can cause serious health problems, including damage to the nervous system, memory loss, tremors and even kidney damage. The WHO classifies mercury as one of the chemicals of greatest concern, as it is neurotoxic and carcinogenic. Chronic or acute exposure to mercury can have serious effects, ranging from fatigue to death in cases of severe intoxication.
Hydrogen sulfide detection and analysis
Hydrogen sulfide (H2S), or hydrogen sulfide, is a naturally occurring gas produced by the decomposition of organic matter, particularly in sewage and wastewater treatment plants. Used in the chemical and metallurgical industries, it is colorless and distinguished by its rotten-egg odor, perceptible to the human sense of smell at very low concentrations of the order of ppb (parts per billion), making its smell particularly unpleasant. Highly toxic by inhalation, it can cause eye and lung irritation even at low concentrations. What's more, it is extremely flammable, with high explosive limits, making it a dangerous gas in industrial environments.
