How To Select a Hydrogen Fluoride Gas Detector

What Does a Hydrogen Fluoride Gas Detector Do?

Hydrogen Fluoride Gas Detectors can accurately measure concentrations of hydrogen fluoride gas in the atmosphere. These gas detectors are used to track fugitive emissions from pressurized equipment, protect workers, and alert plant failure by detecting gas leakage faster and over a wider area than point detections. Hydrogen Fluoride Gas Detectors are usually installed around the perimeter of a plant, processing, or storage area or located close to specific plant products that present a potential gas danger.

Types of Hydrogen Fluoride Gas Detectors

Portable Hydrogen Fluoride Gas Detector: Using a portable Hydrogen Fluoride Gas Detector is an effective way to ensure the personal health of employees working in environments that may be at risk of high concentrations of hydrogen fluoride gas. These compact tools are an incredibly effective and functional measurement tool.

Fixed Hydrogen Fluoride Gas Detector: Fixed hydrogen fluoride detectors are installed in areas that are vulnerable to high concentrations of hydrogen fluoride gas. A fixed detector, also known as a transmitter, incorporates a target gas sensor capable of measuring the HF gas in ppm.

Applications

Hydrogen fluoride is used in various industries, including chemical production, which includes hydrocarbon, fluorine, and uranium hexafluoride, along with gasoline production and metal pickling. Various chemicals, manufacturing processes, or natural phenomena, including alumina baths, welding, and volcanoes, are sources of HF gas emissions.

 

Factors affecting selecting a Hydrogen Fluoride Gas Detector

Knowing the prime target and the motivation for gas detection is the first step in choosing the right solution.

If the primary goal has been established, selecting the correct equipment can be done by asking a series of questions, which fall into three specific categories:

  • Gasses to be detected and where they can originate
  • Position and environmental conditions of the detected area
  • Facility used for operators and routine service workers

Depending on the answers for these series of questions, the user should select between a portable Hydrogen Fluoride Gas Detector and fixed Hydrogen Fluoride Gas Detector.

Depending on the model, a portable HF Gas Detector provides various measuring ranges, visual and audible alarms, high-performance sensors, data logging, and long battery life (up to 200 hours), all in a simple-to-use, durable, and easy-to-carry casing.

There are different types of fixed detectors used for monitoring hydrogen fluoride, those with or without display, those who use colorimetric paper as an optical analysis system or as electrochemical sensors, stand-alone devices, or combined with a fully fixed gas detection system.

Materials

Hydrogen fluoride is also known as hydrofluoric acid and is a chemical compound available in liquid or gaseous form.

Hydrogen fluoride is used in various production processes, including chemical, gasoline, hydrocarbon, fluorine, uranium hexafluoride, and metal pickling.

The dangers of hydrogen fluoride

Hydrogen fluoride is a gaseous substance with a pungent scent. It is corrosive, quickly liquefiable at room temperature, and it can cause fires by chemical reaction with other elements. Contact with the liquid form of hydrogen fluoride can cause very severe burns, and when inhaled can be extremely toxic to humans, causing respiratory and liver damage and can lead to death. Due to the gas’ dangerous properties, there is a clear need to track its existence to avoid accidents and thereby protect facilities and staff.

Hydrogen Fluoride Detection Process

Hydrogen fluoride can be detected by odor, but only an HF Gas Detector can reliably measure concentrations of this highly toxic gas. Usage of a stationary or portable ppm hydrogen fluoride gas detection device is recommended. Colorimetric gas detector tubes, which are also included in the portable group, can determine the presence of hydrogen fluoride. This measuring device, combined with a manual sampling pump, is accurate, fast, and simple to use. Dosimeter tubes, used without a sampling pump, often allow for exact monitoring of the average gas exposure level. There are different types of fixed detectors used for monitoring hydrogen fluoride, some with or without display, colorimetric paper as an optical analysis system or as an electrochemical sensor, in the form of a stand-alone device or combining a full fixed gas detection with a controller package.
