module; the data is then stored and can be used as detailed statistical data using the dedicated software. The software can also produce reports and also configure individual alarms for particular sensors.
The wireless system can integrate with the building automation system; dedicated Software allows an entire wireless system to be managed and controlled from a single PC, the software can set parameters for Temperature, Humidity and concen-
trations of hazardous gases which can then activate and control the air conditioning and ventilation systems, it can also turn on/off heating and as a last resort trigger building alarms.
The collected data is presented on the controller PC in real-time. The graphical display enables the user to identify trends and patterns in the sampling; simple user interfaces enable ease of use and operation
of the software. The user can monitor and control each individual unit and sensor using the software. Limits can be set on each parameter, which when exceeded will set-off an on screen alarm. Relays can also be installed which can give visual and/or audible warnings if the limit is exceeded. The user can create monitoring schedules using the software. This is ideal if monitoring only needs to take place for a set period of time, for example during work hours only.
Continuous monitoring of IAQ enables a profile of the Indoor Air Environment to be created, analysis of the recorded data through dedicated software allows for more efficient management of resources and energy. The software can be used as an analytical tool; trends can be identified, problem areas can be rectified; this should lead to better indoor air environment and safer, more comfortable working conditions.
If the building service engineer has the correct data relating to the day-to-day operation of the air conditioning system improvements to the design and management of the ventilation system can be made. A more effective air-conditioning or ventilating system also has a positive impact on the environment. It would also ensure optimum human comfort, energy conservation, cost effectiveness and health and well- being of those inside the building.

HART®
Communicator/Calibrator Approved Intrinsically Safe The hand-held DPI 620 advanced multifunction calibrator/HART® communicator from GE Sensing (UK) has now been approved for use in potentially explosive
atmospheres by Baseefa, the British certification body. The Baseefa approval carries both ATEX and IECEx certification allowing the instrument to be employed globally in Zone 0 areas. The certification also extends to the instrument’s battery pack, permitting hot swapping within hazardous locations. The approval now further extends the range of potential applications of the powerful communicator/calibrator, especially in the oil and gas and process sectors.
As Mike Shelton, product manager at GE, explains, “The DPI620 now offers plant engineers and technicians throughout the industrial and process sectors a single instrument which can be used for configuration, commissioning, maintenance and calibration, wherever the location.”
To comply with the IS certification, the display has been redesigned and now features a, bright, organic liquid crystal display (OLCD) which offers excellent viewability at a wide range of angles and in virtually all lighting conditions. As with all instruments in the DPI620 family, the IS version is rugged and compact and weather-proofed to IP65. It retains all the software of the existing DPI620 platform and supports Windows CE, providing standard Windows applications and file management while offering the computing power to view pdf files and jpeg images such as loop diagrams, data sheets, safety procedures, spreadsheets and to create text documents.
The introduction of the IS version follows the recent successful incorporation of HART® compatibility into the DPI620 platform. All versions of the DPI 620 now contain a complete HART
library of registered HART device descriptions, making the DPI620 a true communicator/calibrator. Device description (DD) and software upgrades may be simply downloaded free-of- charge, from the GE Sensing & Inspection Technologies website and this includes updating all existing DPI 620 models. World-class pressure-generation and measurement is still an important feature of the IS version, with on-board pressure generation from vacuum to 100 bar pneumatic or 0 to 1000 bar hydraulic, with accuracies from 0.005% FS.

New Low Cost Noise Dosimeters Benefit From an Improved Design
Casella CEL has redeveloped its popular lightweight and cable-free dBadge noise dosimeter to increase its robustness, allowing the dosimeter to be used in the harshest of environments with absolute reliability.
Owing to its popularity for use in mining applications, the redeveloped dBadge now features rubber over- moulding on the case to further increase toughness, and provide protection from the water and dust prevalent in mines or similar environments.
Casella has also added a new model to its noise dosimetry range, the CEL-350L dBadge ‘Lite’, which offers simple functionality at a very affordable price. The ‘Lite’ measures all the same occupational noise parameters as the original dBadge except for the time history of exposure to noise levels, so is ideal for users needing straightforward noise dose results at low cost.
Market Manager Tim Turney commented: “The redesign of the dBadge shows Casella CEL’s commitment to continually improving its range of high quality exposure measurement instruments. The addition of the dBadge ‘Lite’ to the range ensures that cost need not be a deterrent to safety.”
Noise Measurement Company Awarded International Standard
Reader Reply Card no 140 New Distributor Opens Door on Chinese Market
Analox Sensor Technology (UK) has appointed a new distributor, opening up a new market for its products in China.
Analox has recently confirmed a distribution agreement with China-based Skycci Technologies. Skycci will supply a range of Analox products designed for use in industry. These include the Aspida personal gas analyser which was launched in 2009, the Analox 404 which is a wall mounted analyser for use in commercial and industrial premises and the Analox XDI range of detector heads.
The appointment of Skycci Technologies follows Analox’s visit to China Bevtec in July 2010. Part of the purpose of this visit was to recruit distributors to target the market in China, and, following careful selection, Analox is now announcing its first appointed distributor.
Mark Lewis, managing director of Analox Sensor Technology said: “Skycci Technology has extensive experience marketing to the relevant industries in China. This combined with their local knowledge and enthusiasm makes Skycci an ideal partner. The new agreement fits with Analox’s commitment to ambitious growth, in part through introducing our products into new market places.”
Manpo Cong, sales manager of Skycci Technology, added: “Analox products are well established and respected across the world, and we are confident that they will be well received in China’s rapidly growing industrial sector.”

Specialist noise measurement equipment manufacturer Cirrus Research (UK) has been awarded ISO (International Organisation for Standardisation) 14001: 2004. As a leading expert in the creation and production of noise measurement and monitoring instruments, Cirrus applied for the certification as part of its business strategy addressing the growing environmental market that its experts are now providing noise measurement advice too.
Relevant to all companies, the internationally accepted standard is designed to address the delicate balance between maintaining profitability and reducing environmental impact and sets out a framework of essential elements to put an effective Environmental Management System (EMS) in place. This ensures that businesses can identify aspects that impact on the environment and understand those environmental laws that are relevant to their situation.
