  • Gas Monitor Bump Testing vs Calibration

    We are often asked to explain the difference between calibrations and bump testing. This is a controversial subject. OHS would have you do a full calibration before each use. In practice, our customers come up with their own intervals. If the gas monitor is used infrequently, say once a month, it should be calibrated every time to give you confidence that the unit is going to respond as it ...

  • Subsurface Gas Monitoring

    So, what can be done to mitigate the potential drastic effects? Whether a landowner, developer or regulator the objective is identical; namely to ensure that any existing or proposed development remains or takes place safely. But because of the temporal or seasonal effects on ground gas migration, monitoring has to be undertaken over a potentially wide geographic area, lasting several ...

  • Automatic calibration saves big

    Automatic gas sensor calibration technology was developed by Rel-Tek and proven over a decade of industrial applications involving large alternative fuel, transit bus garages. CNG, LNG, LPG and hydrogen fuels present the possibility of explosive gas buildup indoors, so sustaining the accuracy of the installed gas monitoring system is a never-ending responsibility for the owner. Rel-Tek's ...

  • Planning for a Gas Monitoring System

    Do you need a gas monitoring system? Then you already know which gases you want to monitor, you probably have an idea of measurement ranges and accuracy requirements, and perhaps you have a budget for the system. But which other aspects have to be considered, and how do you actually design the system? Whether it is about air quality monitoring, continuous emissions monitoring or process control, ...

  • No Need for Redundant Systems

    How many gas monitoring systems does it take to measure a gas concentration? Strangely enough, the answer is not always one. Gas concentration monitoring is not always an easy task. In the ideal world, a monitoring system needs no maintenance, it is infinitely fail-safe, and it operates impeccable irrespectively of the conditions of the gas. However, then reality hits the system with more or less ...

  • Offshore gas monitoring for health and safety

    Summary The need to maximise availability and to implement the most challenging of drilling plans, while all the time meeting stringent health and safety requirements, places immense pressures on offshore facilities managers. The costs of downtime and any subsequent clean-up due to an incident are unthinkable, and the costs of ill health are growing. Legislation demands the implementation of a ...

  • 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 ...

  • GA3000 monitors graves in Korea case study

    Application Research into gases produced by animal carcasses Equipment GA3000 Location Korea Customer A Korean government research facility supplied and supported by ENInstrument. Requirement Reliable continuous gas monitoring equipment was required for unsupervised monitoring of gas emissions over a three year project. Five ‘graves’ were specially constructed with a lining ...

  • Effects of averaging time on predicted gas concentrations

    The potential consequences of a particular gaseous emission usually relate to a specific averaging time. However, the averaging time associated with gas monitoring data in the region of a discharge may differ from the averaging time implicit in a model employed to predict the concentration resulting from that emission. Tables of factors exist for taking account of such differences and recent ...

  • The latest ground Gas monitoring innovations

    The latest Ground Gas monitoring innovations The traditional methodology for ground gas monitoring has been ‘spot monitoring’ – taking event readings at various set times to predict the sub surface gas regime on both on Brownfield and Landfill sites. This methodology is in general current practice under both the EU Landfill Directive 1999/31/EC which is supported by ...
