Gas Detection 45
Standalone Gas Detection Device
SY2 from GEIT (Italy) is a standalone device, detection for fl ammable gases, toxic gases, CO2
and oxygen.
Certifi ed to: II 2 G Ex d IIC T6 ( Ta - 50°C. + 80°C ), II 2 D Ex tb IIIC T85°C. Ta - 50°C + 80°C.
This makes it particularly suited to the demanding conditions encountered in the chemical and petrochemical industry on & off shore. SY2 can be supplied in different electronic confi gurations: B (Base): Only 4 - 20 mA signal output and calibration via IrDA interface and external Hand Held Programming unit; B/D (Base + Display); B/D/R (Base + Display + Relay); B/D/R/SL (Base + Display + Relay + Se-rial Link); Optional SIL 2 certifi ed combinations.

Opex not Capex for Portable Gas Analysers The CIRIA compliant
GA5000 portable landfi ll and contaminated land gas analyser can now be leased from Geotech (UK), providing an ideal solution for consultants carrying out ground gas
investigations on contaminated land and brownfi eld sites.
Ground gas investigations are typically undertaken as part of Phase II of geo-environmental assessments, and are a planning condition for many proposed developments. Occasionally a stand-alone investigation may be required, where development sites or existing structures are potentially affected by ground gas.
Many consultants currently use CIRIA C665 as guidance for ground gas investigations, assessing the risk posed by hazardous ground gases to buildings. This guidance recommends a minimum of three months’ monitoring for a site with very low potential of source gas generation. Typically, investigations will include the installation of several gas monitoring wells which will undergo a series of regular monitoring schedule to monitor for any gases, mainly methane (CH4
) and carbon dioxide (CO2 ),
as well as measuring fl ow. Some wells will also be targeted for checking for low or falling atmospheric pressure, as this would indicate the land may no longer be producing gas and potential remediation or building could begin.
It is not only development sites that may require gas monitoring. Existing structures can also be at risk from ground gas, and if the gas is from an off-site source then legislation within the Environmental Protection Act 1990 could determine that the land owner is responsible for undertaking any required remedial measures, including ground gas investigations.
The ATEX and MCERTS approved GA5000 from Geotech is a portable gas analyser used regularly in ground gas investigations. The GA5000 can measure up to six gases, including CH4 and hydrogen sulphide (H2
, CO2 S) as well as reading gas fl ow and
monitoring atmospheric pressure, within one portable unit. With its easy to use interface and proven technology providing accurate results, the GA5000 can be used on a wide range of different sites. Geotech continually work with clients to develop the GA5000, with any new features made available to download for free using remote software updates. This makes the GA5000 a future-proof platform for the ever-changing needs of consultants, councils and landfi ll operators.
Many of the features on the GA5000 conform to the CIRIA guidance, including the recently introduced profi ling option. Gas profi ling is a suggested means of measurement listed in CIRIA guidance. This latest feature on the GA5000 offers users the ability to measure the fl uctuations in gas concentration in a borehole or well at a site, either at regular or stepped intervals, without introducing a level of human error in to the results. CIRIA guidance recommends using a fl ow fi rst option to get an accurate fl ow reading. The GA5000 platform allows users to modify or change the gas monitoring process, for example by choosing to monitor fl ow fi rst.
The GA5000 can now be leased from Geotech from one to fi ve years at a fi xed monthly cost, and extended payment plans across six months and 12 months are also available, helping you to own an analyser without the large upfront cost (subject to status).
