10 Gas Detection Independent Producer of Electrochemical Gas Sensors
As an independent producer of electrochemical gas sensors, Membrapor (Switzerland) is fully committed to quality, service and innovation. They aim to meet and even exceed specific customer needs, yet in niche applications. The company policy of founder and CEO Dr. Christian Huggenberger is and has always been to concentrate on the development, manufacturing and marketing of premium sensors, i.e. state of the art products of high precision, reliability and longevity. The result are products with a minimum of service requirement and maximised value for money.
Membrapor offers a variety of over 200 sensors, able to detect 20 different gases. Some examples for innovative highlights of the last decade are the
unbiased NH3 and HCl sensors with fastest response, a 4-electrodes CO sensor with H2 compensation for flue gas analysis and a highly sensitive Formaldehyde sensor. Expecting the EU regulations to ban lead containing gas sensors in the near future, Membrapor already offers since 2011 a lead free, RoHS compliant, long-living O2 sensor with unique output and baseline. Ahead of legislation, this helps to preserve the environment. The development of
the L-type, a novel series of 4-electrode sensors capable to measure gas concentrations in the ppb range with high accuracy, is another innovative milestone.
Since the foundation of the company in 1995 the constantly growing number of satisfied customers is securing Membrapor's steady, healthy and profitable growth. Due to its constant growth, by October 2013 Membrapor will significantly enlarge its production area again. Each one of the entirely committed employees contribute to keep the satisfaction level of their customers high and to grow their number all over the globe. In order to consolidate and strengthen its leading position, a considerable number of projects for product and process improvements as well as for customised solutions are under development at Membrapor.

25993pr@reply-direct.com Expansion of Fixed Gas Detection Transmitters
Bacharach (USA) is pleased to announce the expansion of their GDX-350 Series of fixed gas detection transmitters. Designed to withstand the harsh environments common in industrial applications, the GDX-350 Industrial Transmitters offer an expanded range of sensors for the detection of toxic, combustible and asphyxiate gases in an intrinsically-safe or explosion-proof housing. The GDX-350 transmitters are full featured transmitters designed for integration into any existing system or as a complete solution for new installations. Placing the transmitters in locations where leaks can occur allows for quick detection and response to the smallest breach, protecting human life as well as equipment and property. The GDX- 350 can be used with the GDA-400 or GDA-1600 Controllers to provide simultaneous display and alarm functions for up to 16 monitors.
The GDX-350 series features a large LCD graphic display that shows gas concentrations and engineering units, along with the flexibility to show the last 30 minutes worth of historical data. Utilising the display panel, users can also navigate through the menu to change alarm set points, instrument configurations, or enter into maintenance mode for sensor calibration. Standard LED alarm indicators accompany the display, indicating when low and high alarm conditions are met. An optional relay board is available to provide three, 5-AMP relays that can be used to drive audible/visual alarms, or activate exhaust fans.
Pre-calibrated, user-replaceable “smart-sensors” are available for the GDX-350 transmitters which minimise downtime, reduce costs and simplify basic instrument maintenance by eliminating the need for technicians to perform gas calibrations in the field.
Product feature include: NDIR, Catalytic and Electrochemical sensors available; Electrochemical sensors for detecting CO, O2, H2S, SO2, NO2, H2, PH3 & NH3; Infrared (IR) sensor for detecting CO2; Combustible gas detection with catalytic bead or IR sensor technology; 2 or 3-wire 4-20 mA interface; Graphic LCD for real time monitoring of concentrations; Relay outputs (optional); Optional Modbus RTU interface; Optional wireless data interface; 30 minute onboard data logger; Easy maintenance w/pre-calibrated replacement sensors; Intrinsically safe 2-wire versions; Explosion-proof rated 3-wire versions.
Gases detected and ranges include: Carbon Monoxide (CO) 0-1000 ppm; Oxygen (O2) 0-25% vol; Hydrogen Sulphide (H2S) 0-500 ppm; Sulphur Dioxide (SO2) 0-99.9 ppm; Nitrogen Dioxide (NO2) 0-99.9 ppm; Hydrogen (H2) 0-1000 ppm; Phosphine (PH3) 0-5 ppm; Ammonia (NH3) 0-500 ppm; Combustible gases 0-100% LEL (catalytic sensor); Combustible gases 0-5% vol or 0-100% LEL (infrared sensors); Carbon Dioxide (CO2) 0-5%.
Target markets: Power generation; Steel and metal processing; Food distribution centres; Food processing; Bottling facilities; Breweries and wineries; Industrial processes; Water/waste water; Petrochemical; Oil and Gas.

OxyDetect Oxygen Deficiency Monitor Launched Servomex (USA),
worldwide specialists in gas analysis technology, have announced their entry into the life safety market with the launch of the OxyDetect oxygen monitor.
The first product to be launched under the new
Servomex Gas Detection brand, the OxyDetect is a safe area monitor which utilises advanced non- depleting paramagnetic technology to accurately monitor oxygen levels - without the sensor deterioration that affects traditional electrochemical sensors used in competitor detectors.
Designed for use in life safety applications, the OxyDetect utilises the Hummingbird Paracube Micro paramagnetic sensor, whose industry-leading levels of linearity, accuracy and reliability have ensured its use as a trusted oxygen sensor for the OEM medical market. The OxyDetect therefore demonstrates several advantages over traditional technologies, ensuring users enjoy an unprecedented level of safety and performance as well as a lower cost of lifetime ownership.
New Guide to Gas Detection Published
A new independent Guide to Gas Detection has been published by CoGDEM (The Council of Gas Detection and Environmental Monitoring) to provide industry professionals with a complete reference document on the accurate, reliable measurement of gas concentrations in both process control and occupational safety applications.
This book provides the latest information on UK, EU and global regulations, guidance on flammable, toxic and asphyxiant gases, workplace safety, gas detection requirements, sensor technologies, calibration and performance evaluation.
“There is an emphasis on providing practical guidance throughout this book. For example, a quick reference guide explains the key issues in gas detection system selection, this book will be essential reading for anyone with a professional interest in gas detection.”

The OxyDetect's non-consumable design ensures longevity and eliminates the costs associated with the regular replacement of electrochemical, galvanic or fuel cells, as well as the recognised problems of cell degradation when in use or kept as a stock item. As the OxyDetect's paramagnetic measurement stability also eliminates the requirement for frequent calibration, users avoid frequent labour and downtime costs, incurred either when a traditional cell is calibrated or replaced due to anticipated expiration or sudden failure.
As well as significantly reducing the cost of ownership, saving time and money, the OxyDetect utilises advanced microprocessor-based diagnostics that are safe, reliable and easy to access via a simple front panel digital interface. Suitable for use in indoor environments ranging in temperature from 5°C to 45°C, the OxyDetect offers an isolated 4-20mA output with linear measurement for
simple integration, an output range of 0-25% O2 and a fault alarm via mA jam to 0mA.
“Servomex Gas Detection is proud to deliver this breakthrough in life safety, which changes the game for a gas detection market used to unreliable and ultimately expensive consumable sensors,” says Chuck Hurley, Managing Director, Servomex.
“The OxyDetect is unique – a gas monitoring system is only as good as the sensors it uses, and this is the safest, most reliable oxygen gas detector on the market."
