117 Accredited Calibration of Field Strength Meters
Narda Safety Test Solutions GmbH (Germany) has been awarded accreditation for electric and magnetic field strengths by DAkkS, the national accreditation body of the Federal Republic of Germany. This enables Narda to offer accredited, internationally recognised calibration of field strength meters to their customers.
The calibration laboratory of Narda Safety Test Solutions GmbH in Pfullingen is accredited for electric field strengths in the frequency range 9 kHz to 18 GHz. The calibration range covers up to 300 V/m depending on the frequency, and extends down to 2 V/m – i.e. field strengths that are relevant when it comes to measurements for human safety and environmental field exposure.
The accreditation certificate confirms that the laboratory meets the “general requirements of competence for test and calibration laboratories” according to DIN EN ISO/IEC 17025:2005. The calibration method itself is described in IEEE Std 1309-2005, which is the most comprehensive and therefore globally recognised “Standard for Calibration of Electromagnetic Field Sensors and Probes”.
The calibration certificate gives the customer details of the measured values and their associated measurement uncertainties, as well as additional information about the calibration that was performed. Customers also benefit from the Mutual Recognition Agreement of ILAC (International Laboratory Accreditation Cooperation) which ensures that the accredited calibration certificates from Narda's laboratory are recognised worldwide by leading institutions.
As well as accredited calibration, Narda Safety Test Solutions will continue to offer their factory calibration service. All calibration services can also be combined with maintenance and adjustment. The company can also carry out rapid repairs to Narda equipment because as the manufacturer it has both the know-how and the original spare parts for the product.

26293pr@reply-direct.com Fully Automated Water Analysis with Laboratory Robot
Meet AllPhred. From sample preparation to documentation, the 3900 laboratory robot reliably analyses key waste water parameters, including chemical oxygen demand (COD), total phosphorus and total nitrogen, working around the clock.
The AP 3900 laboratory robot is modular in its construction and can be expanded to adopt other methods where required. Up to ten samples with six different parameters are processed in parallel. All work steps are optimally coordinated in terms of time and are integrated within one another. This saves valuable labour time, freeing up new capacity in laboratory analysis.
Where required, samples are diluted in an automated process or subjected to repeated analysis in a different measuring range. It is possible to attach other samples during the analysis process, or to work through samples according to priority. This ensures flexibility and a quick response at all times.
The relevant information about the samples is recorded using the intuitive software. All information regarding the status and cycle can be called up with a click of the mouse during the analyses. Together with the Hach Lange (UK) cuvette tests used, the AP 3900 ensures optimum transparency and satisfies the most exacting requirements.
Even with the basic version, the purchase pays off, even with thirty measurements per day. The Hach Lange technical field service team analyse the specific situation of a laboratory and calculate the corresponding potential for savings.

26118pr@reply-direct.com Global Distribution Centre Opened
Industrial Scientific (USA), global specialists in Gas Detection as a Service, announced recently that operations went live earlier in 2013 at its newly leased 19,500-square foot facility near Pittsburgh.
The new global distribution centre supports global order fulfillment along with Industrial Scientific’s regional manufacturing and instrument repair operations. Previously housed at the company’s headquarters at 1001 Oakdale Road in Oakdale, Pa., these functions faced operational challenges brought on by business growth.
The distribution centre improves the efficiency of order processing as well as overall responsiveness to customers with its dedicated international, domestic ground, and domestic air processing stations for customer orders.
“Industrial Scientific has experienced significant growth over the last decade,” said Jim Quasey, vice president of global operations. “The distribution centre provides the space needed to efficiently deliver to our customers the life-saving products that they rely on every day.”
The global distribution centre is located in the Imperial Business Park at 150 Crown Court, Oakdale, Pa., 15071.

Did You Know that Particles Contain Quite a Lot of TOC? That is why Filtration and Sample Pretreatment Falsify Measurement Results Significantly.
Water analysis is of great importance for numerous industries. Accurate measuring results help to control and optimise production processes which in turn leads to huge cost savings. Thus, most operators require analysers, that enable accurate TOC (total organic carbon) measurements. Depending on the application, water loads and water composition are subject to high fluctuations. Due to their measuring technique, common analysers block very fast. Therefore, pretreatment and/or filtration are necessary. However, one must be aware of the fact that any pretreatment or filtration will affect the analysers' measuring results. As any removal of particles will result in a less representative sample, the measurement will be inaccurate as well. In contrast, specialised analysers are needed that avoid any blockage.
The LAR (Germany) FlowSampler is an innovative and patented sampling device that uses the anti-isokinetic sampling technique. Samples are siphoned-off from the sample stream against the main flow direction of the stream. Due to the flow speed, big solid particles will not be sucked into the sampling device. Instead of the big solids, all small organic particles that are relevant for the TOC measurement are captured. Thus, samples will enter the analyser unaltered, even if there are complex challenges such as high particle density. Therefore, the taken sample corresponds 98% to that of a grabbed sample.
Additionally, LAR analysers use the ultra high temperature combustion method at 1,200°C guaranteeing the complete oxidation of all carbon containing molecules including the particles within a sample. Not only is the total organic carbon detected by the QuickTOCultra analysis method but due to the sampling technique of the LAR FlowSampler no carbon is lost in the sampling process. Hence the results really do show the TRUE TOC.
In brief, the FlowSampler is an innovative maintenance-free sampling system for all applications.
