Dangerous effects on the human body have a variety of gases used in industry and everyday life. The human sense of smell is not always able to determine the presence of harmful compounds in the air. Gas analyzers come to the rescue. These are devices that not only determine the type of chemical, but also calculate its concentration in the air. Knowing the maximum allowable standards, we can conclude about the danger of being in a room or a closed tank. A wide range of household and professional gas analyzers is presented on the Russian market. The recommendations of our experts will help potential buyers make the right choice.
Recommendations for selection
Appointment. All devices for measuring the concentration of gases can be divided into two groups.
Household appliances are easy to use, they are easy to set up and give a user-friendly signal of danger. Most often, for household use, models are required that measure the level of carbon monoxide, methane, propane, butane. A distinctive feature of household models is an affordable price.
Professional gas analyzers are widely used in various sectors of the national economy. Among them there are both universal models and highly specialized ones. A distinctive feature of professional devices is the high accuracy of measurements, the presence of built-in memory, multifunctionality.
Type of gas detector. The most important part in the gas analyzer is the detector (sensor, transducer). Specialists distinguish several types, they differ in the principle of action.
A thermochemical detector measures the thermal radiation resulting from a chemical reaction. Most often, gas is oxidized on special catalysts with heat release.
Magnetic sensors are used to determine oxygen. Depending on the concentration of the gas, a different magnetic reaction is observed.
Gaseous compounds are capable of absorbing infrared waves. Each gas has its own wavelength, which becomes the basis for determining the concentration of one of the components of the gas mixture.
Current source. Gas analyzers require electricity to operate.
Portable models are equipped with rechargeable batteries or batteries. A useful option in such models will be a charge indication. The user will be able to timely replace the batteries or recharge the battery.
Stationary gas analyzers can be powered by a 220 V electrical network. Such models are most often used in chemical laboratories or research centers.
Measurement result. Depending on the purpose of the device, the measurement results can be displayed on the display or the notification is carried out using sound, light or vibration alarms. If professionals care about numerical values, graphs, analysis and memorization capabilities, then in everyday life it is enough to draw the user’s attention with the help of sound, a certain color of the screen or vibration.
We have selected 7 of the best gas analyzers in our review. All of them are sold in the Russian trade network. When distributing places, the editors of the journal expertology relied on the opinion of the expert community, taking into account the feedback from domestic consumers.
