Gas detectors are one of the most important safety tools in various industries. By accurately measuring the concentration of different gases in the environment, these devices plays a vital role in maintaining the health and safety of employees and preventing accidents. In the following, we will examine the types of gas detectors, how they work and their applications.
Gas detectors for measuring the concentration of gases are generally divided into two categories: fixed and portable. The gas detector is used to ensure the safety of industrial environments. Any industrial unit can use this equipment to measure the concentration of gases based on the amount of gases in the process. Determining the gases in the environment is one of the most important parameters for ensuring the safety of employees and equipment of an industrial unit. With the help of this equipment, it is possible to measure the concentration of different gases such as oxygen, flammable and all toxic gases such as H2S, CO, SO2, Cl2, HCN, NO2, NH3, etc.
Portable gas detectors, as their name suggests, can be carried and do measurement in different environments such as tanks, containers, etc. Fixed gas detectors are used in environments where constant monitoring of existing gas levels is required.
Portable gas detectors are divided into two permanent and temporary groups. Temporary gas detectors with a lifespan of 1 to 3 three years from the time they are turned on, measure without needing to replace batteries, sensors, and other parts, and cannot be used after the end of their lifespan.
In contrast, permanent portable gas detectors, can be repaired and calibrated and can be used for a lifetime. These equipment are more complicated and require more maintenance so that they can be used for longer periods.
Single gas detectors measure only one gas and are suitable for industrial units with a low variety of toxic and dangerous gases.
Quad Gases measure the four gases CO, O2, LEL and H2S, which are the most common gases required for monitoring in most industrial units. This default arrangement of sensors has increased the life span and reduced the cost of this equipment.
Multi-gas detectors are suitable for industrial units that intend to measure several specific gases, because these devices usually give customers the ability to measure up to 6 gases selectively. This aggregation of gases will reduce maintenance costs and the number of gases needed per unit, and give users the initiative to choose a personal arrangement of sensors.
Sensors of gas detectors are divided into four main categories based on the measurement method.
In order to use the gas detector, one must first identify the type of gases in the environment and choose the appropriate gas detector. If using a portable gas detector, turn on the device and place it in the desired environment. The device automatically measures and displays the concentration of gases. For fixed gas detectors, installation and commissioning should be done by professionals. Users should be trained to interpret results and take safety measures if dangerous concentrations are detected.
The price of a gas detector varies depending on the type (fixed or portable), the number of gases that can be measured, the range of measurement and the manufacturer’s brand. Single-gas meters are usually cheaper than multi-gas types. Temporary portable gas meters are less expensive than permanent types, but may be costly in the long run as they require complete replacement. Fixed gas meters are usually more expensive than portable types due to the complexity of installation and more features. To get the exact price, it is recommended to consult with specialized engineers at HIWACO.
The gas detector is a vital tool in ensuring the safety of industrial environments. Considering the variety of gas detectors and their sensors, choosing the right model for each industry is very important. Correct use, regular maintenance and periodic calibration of these devices can significantly reduce the risk of gas leakage accidents and provide a safe environment for employees.
In this regard, as one of the pioneers in providing advanced gas measuring devices, HIWACO has provided comprehensive and reliable solutions for various industries. Using the latest technologies of the world, high accuracy and extraordinary reliability, HIWACO gas detectors are a smart choice for ensuring safety in industrial environments.
By choosing HIWACO instruments, you will not only have a device, but a reliable partner in the process of improving your industrial safety.
Choosing the type of gas detector depends on the type and number of gases in your work environment. Single-gas gas meters are suitable for environments with a specific type of gas, and multi-gas gas meters are suitable for environments with several different types of gas.
Portable gas detector is used for measuring in different environments such as tanks and containers. A fixed gas meter is installed in a certain place and is used for permanent monitoring of gases in a certain environment.
The lifespan of gas detectors are different. Temporary gas detectors usually last 1 to 3 years, while permanent ones can last for years with proper maintenance.
To ensure the accuracy of the gas detector, it should be calibrated regularly. Also, periodic inspections and timely replacement of sensors are necessary.
Yes, correct operation of a gas detector and the interpretation of its results require training. Users should be trained on how to use the device, interpret the data, and take action if dangerous concentrations are detected.
