GASERA ONE HCl, A HYDROGEN CHLORIDE GAS MONITOR TO MEASURE LOW LEVELS OF HYDROGEN CHLORIDE IN AMBIENT AIR

Hydrogen chloride (HCl) is a colorless, highly corrosive, and irritating gas that readily reacts with moisture in the air, eyes, skin, and respiratory tract to form hydrochloric acid. It is widely used in chemical manufacturing, metal refining, surface treatment processes, industrial cleaning, semiconductor production, and waste treatment applications.

Due to its corrosive nature and ability to rapidly form hydrochloric acid upon contact with moisture, HCl poses significant risks to human health and industrial infrastructure. Exposure to elevated concentrations can cause severe irritation of the eyes, skin, and respiratory system, while prolonged or high-level exposure may result in inflammation of the airways, pulmonary edema, and serious tissue damage.

Early and reliable detection of hydrogen chloride is therefore essential for protecting workers, surrounding communities, and industrial assets. The Gasera One HCl hydrogen chloride gas monitor provides fast, accurate, and continuous monitoring of ambient HCl concentrations, enabling rapid response to leaks and emission events. Utilizing Gasera’s patented cantilever-enhanced photoacoustic spectroscopy combined with a Tunable Diode Laser, the analyzer delivers highly selective measurements with detection limits below 10 ppb.

Designed for both field and stationary applications, Gasera One HCl offers stable, drift-free operation, low maintenance requirements, and a recommended calibration interval of 12 months. Its ability to continuously measure low-level HCl concentrations helps ensure workplace safety, maintain regulatory compliance, prevent corrosion-related equipment damage, and support environmental monitoring programs.

HYDROGEN CHLORIDE LEVELS BELOW 10 PPB DETECTION LIMIT

Hydrogen chloride (HCl) is a highly corrosive and irritating gas used in chemical manufacturing, metal refining, and industrial cleaning. Exposure can cause irritation to the eyes, skin, and respiratory system, and at higher levels it may lead to severe respiratory damage and serious health effects. Continuous monitoring of low-level HCl is essential to protect people, equipment, and the environment from accidental releases and long-term exposure.

GASERA ONE HCl hydrogen fluoride gas monitor is based on combining ultra sensitive cantilever enhanced photoacoustic detection technology with a tunable diode laser (TDLAS) source operating at a fundamental spectral absorption line of hydrogen fluoride (HF).

This combination provides enough sensitivity (parts per billion level!) to reliably measure ambient background levels of hydrogen fluoride (HF). It also gives an exceptionally high level of stability with a recommended re-calibration period of 12 months, and thus it offers a low total cost of ownership.
