7 best gas analyzers

Review of the best according to the editors. About the selection criteria. The the material is subjective, is not advertising and is not serves as a guide to the purchase. Before purchase is needed consultation with a specialist.

The burning of natural gas and other fuels contributes to the release of harmful waste products that are difficult distinguishable by human sense of smell. Gas supply communications to counter or stove may become leaky due to cracked hose or loose fitting winding. To find leaks, use gas sensors that recognize the composition of the air mixture. Them used to configure heating boilers, geysers, checking flanges and elbows. From the sensitivity and quality of the device depends on the performance of other equipment and human life, therefore, it is important to choose the right leak detector. This will help our review of the best gas analyzers and expert advice on choosing.

How to choose a gas analyzer

When deciding to buy a gas analyzer, pay attention to the key The parameters described in the characteristics of the device:

  1. Type of fuel and detectable gas. Depends on where and for what tasks can I use the device. When burning protozoa fuels such as natural gas or diesel fuel are enough simple gas analyzer designed to trap residues carbon monoxide (CO₂). When it’s important not only to find a leak harmful flow, but also evaluate the overall environmental friendliness of the exhaust, use models capable of detecting nitric oxide (NO₂). If in fuel oil is used fuel oil, a sensitive device is needed also to sulfur dioxide (SO₂). For solid fuels gas detectors are used, the sensors of which are protected from increased temperature and dust. When looking for a leak of unburned gases, then choose devices with sensitivity to methane (CH₄) or propane (CH₃N).
  2. Range of measurement and sensitivity. Optimal the recognition range for CO₂ residues is 0-10000 ppm But the sensitivity of leak detectors is different – some devices capture any values ​​above 0, while others only from 100 ppm. Than lower threshold is better.
  3. Interface. This is another important parameter that affects usability of a gas analyzer. Some models have only color diode circuit, where each color is a certain level harmful gas content. Others have a digital display designation or variable scale, which gives more accurate results.
  4. Response time. So that the device analyzes the composition of the gas and gave out the presence of harmful components, it will take time. Interval can last from 2 to 60 seconds. When you need to do a lot measurements, choose a faster gas analyzer.
  5. Dimensions and weight. Portable devices are more convenient to carry with by themselves when they are compact and light. Leak detector sizes may be from 50x20x100 mm to 70x40x200 mm, and the weight varies from 100 to 500 g
  6. Battery capacity The gas sensor can work from battery or batteries, which lasts for 3-10 hours continuous operation. The larger the time indicator, the less often you have to interrupt for recharging or change batteries.
  7. Permissible operating conditions. Some readers can apply only at temperatures from +4 degrees. Others save correct operation of the sensors at negative values ​​up to -10º C. If you have to take samples in unheated rooms (attics, basements, etc.), choose the second option.

Gas analyzers are mobile and stationary. Just such Categories contains our TOP 7.
