SVAN 977SVAN 977 Class 1 Sound & Vibration Level Meter and analyser is designed to meet the needs of both environmental monitoring and occupational health and safety monitoring specialists. Its exceptional hardware design also enables the measurement of ultra sound frequencies in the 40 kHz band.
The SVAN 977 provides broadband results with all the standard weighting filters and also offers an incredible time history logging capability providing broadband results and spectra with adjustable double (long and short) logging steps. Audio recording can be performed simultaneously with time history logging as either a separate wave file or as audio events inside time history files. This solution enables noise source recognition and data post-processing. Manual and automatic triggering of audio recording is also available. Measurement results are recorded in three acoustic or vibration profiles enabling measurements to be performed with 3 different filters (e.g. A, C, Z) and 3 different detector time constants (e.g. Fast, Slow, Impulse). Measurement data is stored on a µSD card and can be easily downloaded to a PC using SvanPC++ software over either USB or RS 232 interfaces. The powerful DSP (digital signal processor) used in the SVAN 977 instrument can simultaneously operate in meter mode and perform real-time 1/1 or 1/3 octave analysis including statistical calculations. Additional functions like real-time FFT analysis and Rotation Speed Measurement are also available. The highly developed user interface works on networks like GPRS, Ethernet or WLAN for both remote data download and settings configuration. The built-in Bluetooth™ interface together with smart-phone application, SvanMobile, extends measurement capabilities with all the features offered by smart-phones including text/voice comments, photo, video, GPS position etc. The instrument is powered by four AA standard or rechargeable NiMH batteries (separate charger is required), from an external DC power source or USB interface. The robust and light weight design complete the exceptional features of this next generation instrument. |

Main Applications
Related ProductsSupervisorSupervisor is the PC software package dedicated for health and safety specialists. Software supports the whole family of Svantek instruments dedicated to health and safety market including the BIG TRIO: SVAN 971, SV 104 and SV 106.
Each instrument connected to the Supervisor is remembered enabling automatic creation of instruments' database containing important information such as uploaded settings and firmware version, calibration validity date or instrument clock time. Intuitive tools for data organization upon downloading provide folder-structured database as well as files tagging by locations, users or tasks capabilities. Downloaded data files are automatically categorized by measurement time and assigned to the instrument's serial number enabling fast & easy data browsing. In practice this means no more time-consuming data search through PC storage. Supervisor software adjusts itself to the user’s requirements. In case of simple applications that require analysis of only main results such as LAeq, LAFmax or LCpeak, Supervisor offers quick previews and reporting without necessity of data files opening. More advanced applications are handled within sessions where user decides on the type of analysis to be performed. Those who create noise or vibration reports on a daily basis will appreciate possibility of creating report templates, which once created can be applied to series of measurement files. Whenever necessary user can select data files and create personalized reports with couple of clicks. FEATURES

SvanNET
|
SvanNET is a relay server supporting connection between PC and Svantek instruments in case of 3G communication. The SvanNET allows usage of all type of SIM cards with a 3G modem regardless if they have public or private IP. The connection over the SvanNET allows users to:
use a mobile phone or tablet to watch real time measurement results, manually download files and reconfigure the station, manually download files and reconfigure the station using SvanPC++_RC module, use the SvanPC++_RC application based on MS Windows® for automatic control of the noise monitoring stations, data archiving, automatic web publication, etc. |

SvanMOBILE
|
SvanMOBILE is an Android application for devices running on Android platform extending functionalities of SVAN 977 / 979. SvanMOBILE allows to link measurement files from sound level meter to media files from smartphones such as photos, video or audio recordings. Anyone who makes measurements in the environment will appreciate the fact that SvanMobile can be used to automatically add weather data and GPS position to report on the measurement. To communicate with SVAN 977 / 979 the Bluetooth interface is used.
