  • HAV mis-measurement – to no standards whatsoever…

    Misunderstanding Hand Arm Vibration monitoring marketing material can put hands and safety policies at risk. Caveat emptor. We are regularly asked about new vibration measurement technology, particularly re the latest hand-held, glove or wrist mounted transducers that are presented as the latest assessment improvements. Whilst they may be useful tools, unfortunately some claims have been ...

  • Using biofilms for monitoring metal contamination in lotic ecosystems: The protective effects of hardness and pH on metal bioaccumulation

    Biofilms can make good bioindicators and biomarkers, offering a convenient tool to monitor metal contamination in streams that results from mine tailing sites. Biofilm metal content (Cu, Zn, Cd, Pb) as well as diatom diversity and the presence of teratologies (diatom abnormalities) were determined for biofilms from rivers with a variety of physico‐chemical properties across a metal ...

  • Monitoring of water node in wroclaw

    Background Wroclaw's water node has complicated structure. The river Odra has 3 main riverbeds and a lot of channels which are located in the centre of town. There are almost 100 hydro buildings which control flow of the water through the city and protect it against theflood. The great flood in 1997 proved that no one has control over it. Communication systems failure caused ...

  • What is Long Term Noise Monitoring?

    It might sound simple, but long term noise monitoring can mean different things to different people. There is no standard definition for what long term noise monitoring is, but here is a summary that covers the basics. I first presented this presentation at the IOA Eastern Branch meeting and wanted to share my thoughts on what classes as long term noise monitoring. I’ll also discuss ...

  • Fuel Cell Voltage Monitoring Considerations

    Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There ...

  • Easy payback from biogas monitoring

    There is a strong business case for biogas monitoring and CHP protection. A fixed biogas analyser may cost some £6-10,000 and monitor gas every few minutes day and night. By comparison it can save its own cost many times over by protecting CHP engines from expensive unplanned downtime, biogas engine ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Continuous monitoring of moisture present inside a process chamber

    Problem Statement Moisture inside a process chamber is a big silent killer during wafer production. When production yield goes down, it is hard to pinpoint the source of the problem. Most of the time wafers need to be sent to labs for analysis, while production is stopped. If the problem is related to a high level of moisture inside the reactor, there are several factors that can cause ...
