Today is the first blog post in what will be a new section called ‘Product Spotlight’ in which we will pick a product category related to the gas and/or oil industry and highlight a range of associated products. The idea being to provide you with a comprehensive overview of products some of which you may not be familiar with. As we are a fairly new blog we are always open to feedback so pass on any comments you have via our contact page. For today’s Product Spotlight we have chosen Gas Detectors.
Fixed Gas Detectors
If you are in the market for a fixed gas detector you will be happy to know that you are somewhat spoilt for choice. There are a variety of different products that come with different features such as explosion-proof stainless steel housing, IR, HART port connectivity, LCD screens of various designs, LED displays etc. Fixed gas detectors are designed to be highly accurate and of course reliable. They are often used to support critical functions in plant operations and can be used to monitor toxic and combustible gases. You will find fixed gas detectors to handle open-path, catalytic bed and point infrared measurements.
Open Path Gas Detectors
Open path gas detectors provide an increased coverage area to compliment other detection products/systems. They are usually designed to have quick response times and many products now offer built-in automatic calibration.
IR Open Path Gas Detectors work by distributing an infrared beam of light out and then detecting any gas which is sensed along that beam. The beam itself can range from a few metres to a few hundred metres in length. The detector can be contrasted with an IR point sensor.
Open Path Gas Detectors are mostly used in the petroleum industry where they assist with prompt gas leak detection. They may also be used in coal mining and any other industry where flammable gases can occur.
Manufacturers such as Boreal offer products such as the GasFinder3 Laser Gas Monitor which can be used for the measurement of GHG emissions. It is particularly handy for monitoring landfill sites. Boreal also offer dual channel analyzers capable of measuring lengths of 750m (max length depends on gas) and multi-channel analyzers for measuring multiple channels (up to 8).
Remote Flammable Detectors
Remote flammable gas detectors are useful for monitoring in Class 1, Div 1 zones. Honeywell Analytics one of the main manufacturers of RFD products and has a range which offer features such as being able to be mounted up to 100 feet away from the base transmitter. Communication connectivity options include RS485 and MODBUS RTU communication.
Portable Gas Detectors
Portable gas detectors are very useful for those looking for a mobile solution for situations such as confined spaces and spot leak tests. You can find portable detectors that can monitor atmospheric hazards such as toxic gases, combustible gases and oxygen levels. A variety of different products are available on the market, each designed around specific uses. Honeywell Analytics are one of the leading manufacturers and you will find products with features such as:
- Lightweight design (after all, it you will probably be carrying it all day!)
- Re-chargeable batteries with long life
- Water protection (For e.g. IP68 rating)
- Rugged design, to survive rough handling and drops
- Water resistence
- LCD screens
- Data-logging capability
- Audible, visual and vibrating alarms

So there you have it. Our first Product Spotlight. We hope to grow this blog over time so really value any feedback that you have. It would be great if you could spend a couple of meeting passing on any comments via our Contact Page. Thank you and we look forward to sharing another Product Spotlight with you soon.
