The V9000 Seismograph is a portable battery operated ground vibration monitor, housed in an industrialised casing to withstand high intensity environments.
Primary industries monitoring ground vibration include: Blasting
Piling
Demolition
Construction
Traffic
The V9000 also includes new features such as:Internet based remote capability
Frequency plotting in accordance with BS 5228 Part 2: 2009 and BS 7385 Part 2; 1993
Multiple text alarm functions
Larger screen with graphical representation
7 day timer function
Sleep mode
Basic and custom set up
Data storage for all 3 axes
Extended battery life of up to 40 days
Software
Once collected the results can be downloaded to a PC using the vibrock plug and play software. It can then be analysed after being exported to an excel spreadsheet.
Two Stage alarm - The two stage alarm comes with a standard 10 metre cable length, and battery charger. The alarm only uses power when it is activated, so the internal battery will last for between 3 – 4 months before requiring a re-charge. When activated, the alarm will operate for 15 seconds
before re-setting. The two stage alarm can work in conjunction with the text alarm function, on Seismographs which have the modem fitted.
Optional Extras
Twin Channel Option - the twin channel transducer enables the V9000 to take measurements on a common time base in two locations simultaneously. It is also capable of measuring vibration dose values (VDV) to BS 6472 Part 1:2008
