38 Health & Safety Acoustic Camera for Spatial Mapping
Cambpell Associates (UK) is proud to present the acoustic camera Nor848 with outstanding performance. The camera frontend contains 225 microphones enabling the user to perform noise analysis with a clear view of the spatial distribution of the sound.
The system is easy to set up in the field. Just power the selfcontained unit from mains or battery and connect the LANcable to the computer. Nor848 weighs only
15kg and has more than 25dB spatial mapping range without ghost-spots. Reader Reply Card No. 115
Affordable Vibration Monitoring Solution Launched
Svantek (Poland) designers of innovative noise and vibration monitoring instrumentation, is proud to announce the launch of its new SV106 Human Vibration Meter and Analyser. This up-to-the minute instrument, which is capable of measuring both hand-arm (HAV) and whole body vibration (WBV), is so advanced that it can measure vibration simultaneously on both hands, using two tri-axial accelerometers.
Monitoring and control of vibration in the workplace, both HAV from hand-held power tools and WBV from machines producing elevated vibration levels, is essential to avoid prosecution under the Control of Vibration at Work Regulations 2005, as well as to prevent harm to employees, such as the excruciating Vibration White Finger and Carpal Tunnel Syndrome and long-term back pain.
The lightweight, pocket sized Svantek SV106 analyser with its high-resolution colour display provides a completely new approach to vibration monitoring. Featuring six channels for vibration and two channels for static force measurement, the innovative SV106 can also be used to measure whole- body vibration when used with a seat accelerometer.
The instrument provides both octave and third octave real time band analysis and fully complies with standards ISO 8041:2005 and ISO 2631-1,2&5 (including VDV and MTVV) for human vibration and ISO 5349 for hand-arm vibration.
Data from SV106 can easily be downloaded to any PC for fast and accurate analysis, troubleshooting and reporting, using a USB interface and Svantek’s dedicated SvanPC+ software. The device allows advanced data-logging including spectral analysis; the memory can also be expanded by using a micro SD flash card.
The SV106 is a cost-effective solution for HAV and WBV measurement – a complete solution is available in the UK for less than £2,500. Yet although the solution is very competitively priced, it boasts all the features of far more expensive monitoring systems.

The sound signal from every microphone as well as the video from the integrated optical camera are recorded and stored in the computer. Both live level plots as well as post-processed analysis are available with the user friendly software package that runs on the included state-of-the-art MacBook Pro computer. By moving the cursor in the picture you may analyse and listen to the sound in the selected directions, even in real time.

Isotropic Field Analyser
Narda Safety Test Solutions (Germany) presents the EHP-50D isotropic field analyser, an improved version of the measuring probe for low frequency electromagnetic fields from 5 Hz to 100 kHz, which expands the measuring range of their portable, wideband NBM- 550 measuring set from 5 Hz to 60 GHz.
The EHP-50D probe was specially developed for assessing industrial workplaces in accordance with current international standards, and for measurements on industrial equipment. Simultaneous measurement of all three axes coupled with a dynamic range of up to 150 dB ensures that signals can be captured quickly, reliably and over a wide range.
The built-in spectrum analysis feature means that measurements targeting individual events can be made while neighboring frequencies are effectively blanked out. The optical interface enables measurements to be made remote from the NBM-550 in locations that are difficult to access or are highly exposed. Equipped with a data
logger and Lithium-ion battery, the EHP-50D can also operate for up to 24 hours in stand- alone mode and the results read out to a PC on completion of the measurement.
