What is the most common gas detector?
The most common gas detectors are designed to detect toxic or combustible gases and vapors. There are various types of industrial gas detectors to choose from that can be used at any worksite. The key to choosing the right device is knowing what risks your company faces at each location.
Single Gas Detectors: This type of monitor is designed to detect a single gas or vapor such as carbon monoxide, oxygen, phosphine, or hydrogen cyanide. These are often smaller and lighter than multi-gas detectors.
Multi-Gas Detectors: These are portable and lightweight devices that can simultaneously detect up to six gases. They’re usually less than a pound and have larger screens to display readings Gas detection Australia. They also have a better life, detection range, and alarms set.
Enhanced Laser Diode Spectroscopy: This technology works through a sensor that uses laser optical technology to analyze a gas’s unique harmonic fingerprint. They have a great advantage over other types of sensors because they do not provide false alarms from other gases in the environment.
Catalytic Bead Sensor: This is a popular combustible gas detector that consists of a tiny sensing element (sometimes called a “bead”) made of platinum wire coils covered with a ceramic base and then with a catalyst dispersed on top. It can be customized to fit a variety of applications and is one of the most cost-effective gas detection options available.
Electrochemical Gas Detector: These gas detectors use diffusion barrier technology to measure the concentration of a gas. The diffusion barrier allows the gas to diffuse through a porous membrane to an electrode, where it is either chemically oxidized or reduced. This changes the electric current on the sensor, which sets off an alarm when a certain concentration of gas is reached.
