  • BUMP TESTING AMMONIA (NH3) SENSORS

    Bump testing a gas sensor involves flowing a concentration of gas that is slightly higher than the Low alarm setpoint of the gas detector for a short period of time (1-2 minutes or less). The purpose of a bump test is to confirm that the sensor responds to the presence of gas, the low alarm will activate and the gas detector overall ...

  • Axetris Sensor Field Test

    The Axetris LGDs were operated continuously for two years. After intensive laboratory testing, they went out into the field in 2015. Axetris was able to test the functionality of its sensors under real-life conditions thanks to the support of the Linth waste incineration plant. The gas concentration measuring devices called laser gas detectors ( ...

  • How can you measure Peracetic Acid separately from Hydrogen peroxide, Isn’t there hydrogen peroxide in PAA?

    We receive questions of this sort frequently and the questioner is partly right. Peracetic acid (PAA) is formed in an equilibrium mixture with hydrogen peroxide and acetic acid, so in a mixture of PAA, hydrogen peroxide and acetic acid, PAA is being continually formed by the reaction of hydrogen peroxide and acetic acid, and peracetic acid is continually breaking down to reform hydrogen peroxide ...

  • Gas Dilution With The Equal Capillaries Technique

    The advantages of the equal capillaries technique are surprising and leads to reach accuracy values of one order of magnitude higher than all the other dynamic dilution techniques. This comparison will be supported by analyzing the accuracy available with two different techniques. Nozzles (sonic or non-sonic) technique With this technique, a series of different size nozzles is used ...

  • Chlorine Safety and Prevention: How to Protect Yourself from Chlorine Leaks

    While chlorine gas is widely used in swimming pools, water treatment facilities, cleaning products, pharmaceutical products, and in many other industries, the gas is highly toxic when handled improperly. Training your workers on how to safely use chlorine is one part of health and safety best practices; monitoring your workplace for chlorine leaks is another. Learn about the hidden dangers in ...

  • Doing The Dos: Five Tips For Taking Care Of Your Sensor Diaphragm

    For all continuous output pressure sensors, no matter the application, the component most sensitive to external factors, and most crucial to sensor functionality, is the sensing diaphragm. If it is not working correctly, either your readings will be incorrect or, in extreme cases, you will have no readings at all. So often in the world around us, we hear “Don’t do this” or ...

  • Typical Sensor Location Considerations

    The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

  • Doped nano–phase tin oxide thin films for selective gas sensing

    The paper deals with the development of ethanol gas sensing films of tin oxide nano–particles which are insensitive to saturated aliphatic hydrocarbons, such as gasoline vapours. Stannous alkoxide (particularly iso–propoxide) and tin 2–ethyl hexanoate in solution have been used for fabrication of tin oxide films on alumina substrates with two pre–fabricated gold electrodes. For achieving ...

  • How Often Should Gas Detectors be Calibrated and by Whom?

    Calibration frequency is one of the most commonly asked questions concerning the use of gas detection instruments. Common factors to consider when deciding how frequently to calibrate are: type of sensor, type of gas detector (fixed vs. portable), the required use and accuracy of the detector, manufacturer’s recommendations, how confident you are about the functioning of your instrument ...

  • Hydrogen annealing ovens case study

    Application Moisture is measured in hydrogen annealing ovens. Problem Hydrogen gas is used in annealing furnaces manufacturing stainless steel and other metal parts. High-moisture concentrations in the hydrogen will oxidize the metal, resulting in an unusable product with a surface finish that is too dark. Equipment Any ...

  • The Other Side of Zirconium Oxide case study

    Regular Fuel Efficiency Applications Separate Oxygen and Combustibles Sensors In standard flue gas applications for Thermox analyzers, the user generally tries to extract the maximum energy from the fuel and transfers as much of that energy as possible to the process.
