Gas Detection The Smallest Portable Gas Detector To Measure Up To Six Gases


The new X-am 5600 from Draeger (Germany) is believed to be the smallest portable gas detection instrument for the measurement of up to six gases. With an ergonomic mobile phone design, it features innovative infrared (IR) sensor technology and provides accurate, reliable measurements of explosive, combustible and toxic gases and vapours, as well as oxygen.


Ideal for personal monitoring applications, this light yet robust detector is designed for single-handed operation in tough industrial environments and is ATEX approved for use in explosive areas classified as Zone 0.


By using a combination of innovative Draeger IR sensors and the latest Draeger XXS miniaturised electrochemical sensors, the Draeger X-am 5600 can detect a wide variety of hazards. These include O2, CO, H2S, H2 , CO2, Cl2, HCN, NH3, NO, NO2, PH3, SO2 and organic vapours.


Immune to poisons such as hydrogen sulphide (H2S), Draeger IR sensors ensure dependable warnings against explosive and combustible hazards such as hydrocarbons and carbon dioxide. Offering a low cost of ownership, they offer an extended sensor life of up to eight years, twice as long as catalytic Ex sensors. In addition, they only


require calibration every 12 months and, as a result, significantly reducing maintenance costs. The IR Ex sensor provides reliable measurements of hydrocarbons within the lower explosive limit (LEL), and from 0-100 Vol.-% for methane, propane and ethylene. The IR CO2 sensor offers a measurement resolution of 0.01


Vol.-%. Where accurate monitoring of explosive substances and carbon dioxide is needed specifically, Draeger offers a Dual IR CO2/Ex sensor. Hydrogen, which is often present in steel making applications but is not usually detectable with IR technology, can be monitored by combining a Draeger XXS electrochemical H2 sensor with the Draeger IR Ex sensor.


Designed with the utmost safety in mind, the Draeger X-am 5600 features gas inlets on both the top and front to ensure reliable warning of a hazard, even if a gas inlet is accidentally covered or it is inadvertently placed inside a jacket pocket. A large illuminated display means that readings can be seen at a glance and retro-reflective panels ensure easy location in the dark or in water. With a clear 360º visual alarm, the unit automatically emits vibrating and multi-tone audible alarms as soon as a gas is detected.


An optional external pump is available with hoses up to 20m for pre-entry measurements in tanks or pipelines. In addition, the Draeger X-am 5600 can be used in conjunction with the new Draeger X-zone to provide wireless area monitoring. Designed to save time and reduce workload, the Draeger E-Cal Automatic Test and Calibration Station and the Draeger Bump Test Station are also ideal system extensions.


Equipped with a data logger as standard, the unit also allows data such as measured values and configurations to be transmitted via infrared interface to a PC. The data can then be analysed using the Draeger Gas Vision software, with optional user registration being carried out via the Draeger CC-Vision software.

A new static gas analyser for anaerobic digestion (AD) biogas, and landfill gas monitoring suits tight-budget demand with top-quality design, components and engineering. The new GA3000 uses Geotech (UK’s) robust, field-proven technology to bring low-cost to automated fixed- position monitoring of methane-rich biogas. Easily operator installed, user field-calibrated and zeroed, the compact, self-contained, single-cabinet


GA3000 has gas conditioning as standard. It continuously analyses CH4, CO2, O2 and optionally, H2S at 0-5000ppm. They are measured, at user- set timings, and supply data via three or four, 4-20mA local outputs. Users


also set alarm levels and can see screen-displayed readings on a large, clear, backlit display.


The GA3000 is ideal for AD, wastewater sludge treatment and landfill gas extraction.


AD is increasingly being used in waste processing and biogas production to recycle food and farm waste, avoid landfill and generate biogas and energy from waste. These AD installations, large and small, need continuous gas analysis to optimise AD, maximise output and ensure


safety and compliance with environmental guidelines and legislation.


This new robust, reliable and cost-effective system provides continuous and accurate sampling of methane, carbon dioxide and oxygen from a single sample point. Hydrogen sulphide sampling is a GA3000 option. User field calibration of the analyser and exchange of the optional hydrogen sulphide (H2S) sensor reduce operational costs.


With no training required and engineered for low ownership cost, this ISO 17025 calibration accredited unit is designed for quick and easy self-installation in any country, worldwide. User relocation of the GA3000 is just as easy. With gas


conditioning included as standard, to ensure top quality gas analysis, the user-replaceable H2S sensor and analyser ‘Hot Swap’ capability offers zero downtime.

Ion Science (UK) introduces the ATEX approved 3 wire TVOC (Total Volatile Organic Compound) monitor, for use without safety barriers in Zone 2 hazardous areas.


The ATEX certified TVOC can be installed without barriers in a Zone 2 area, to directly replace an existing VOC area monitor. A significant benefit to the customer is the instrument’s easy installation; saving time and reducing costs.


TVOC is also available as an IECEx and ATEX approved 4 wire option for zone 1 areas, with safety barriers. Designed for fixed, continuous area monitoring, TVOC provides rapid, accurate detection of volatile organic compounds (VOCs). The 4-20mA analogue output allows TVOC to be integrated into a DCS control system to give warning or control of high VOC levels within the working environment.


The TVOC photoionisation detection (PID) cell utilises patented Fence Electrode Technology; independently verified as the best performing PID on the market. Its proven PID capabilities provide an unrivalled resistance to humidity and give faster, more consistent results than competing PID instruments. TVOC has been designed for simple servicing and calibration. The PID sensor is accessible and changeable in a matter of seconds.


Target industries and applications for TVOC include; manufacturing and processing plants, refineries, petrochemical, offshore, chemical, waste water treatment, pharmaceutical, indoor air quality, pulp and paper, solvent recovery systems and industrial painting and coating. TVOC is available from Ion Science and its global network of distributors, along with an exclusive range of accessories.
