SV 102+ Dual Channel Noise Dosimeter replaces our ground breaking SV 102. It has been designed for the accurate measurement of noise exposure to ISO 9612 and MIRE (microphone in real ear) measurements to ISO 11904-1.
This new instrument uses a class beating high resolution, full colour OLED screen making it even easier to read; even in full daylight. The small memory capability of its predecessor; the SV102, has been upgraded by adding a microSD card for an incredible amount of storage capability. The sampling rate has been increased from 24 kHz to 48 kHz which enables the measurement of sound in the full frequency band. Also new is an LED that indicates the status of the measurement and changes colour when the noise dose exceeds the limit set.
A unique feature of all SVANTEK dosimeters, including the SV102 +, is their ability to simultaneously analyse 1/1 octave and record audio events . The use of 1/1 octave analysis is the most accurate method for the correct selection of hearing protection to ISO 4869-2 while simultaneous audio recording allows the user to capture and eliminate false sounds affecting the result of exposure to noise.
Unlike classic single channel noise dosimeters, the two channel SV102 + gives the unique opportunity to assess the exposure on both sides of the head simultaneously. This is particularly important where a worker is exposed to noise coming from a dominant directional source where placing the microphone on only one side could understate the true level of noise exposure. Another use of dual channel technology is the simultaneous measurement of noise both outside and inside any hearing protection being used with the use of a SV25S MIRE microphone.
MIRE methodology requires 1/3 octave analysis, another feature uniquely available in the SV102 + . MIRE measurement involves measuring the sound in the ear and performing a one-third octave band analysis on it. Using the SV102 + in conjunction with a special microphone probe like the SV25S, placed at the entrance of the ear canal, makes this all possible . A typical application of MIRE measurement is noise exposure monitoring in telephone call centres where the sound comes from the headphones; an application not suited to classical dosimetry methods.
Calibration of the both the SV102 + and the MIRE microphone is done using a SV34 calibrator. The calibration factor is stored inside the instrument and in the TEDS memory of the SV102+ microphones. This cross checking solution helps to prevent incorrect calibration factors being used.
The SV102 + is a low power instrument and is powered using only two small AAA batteries. It is fully supported by our Supervisor software which is dedicated to Health and Safety applications.
The SVAN 979 Class 1 Sound & Vibration Analyser is our flagship device. Your first impression will be the amazing OLED display which features excellent visibility in all light conditions. The instrument’s lightweight and durable aluminium housing not only gives a sense of a firm grip but also protects the valuable electronic device from damage and any influence from electromagnetic interference.
The SVAN 979 has a very large dynamic range of measurement – over 110dB. It’s high-quality GRAS 40AE microphone allows measurement in the frequency range starting as low as 3 Hz. The measurement path has been designed to allow the use of other microphones should you want to measure very low frequencies or very high levels of noise. The microphone preamplifier has also been reinforced with a collar to protect against mechanical damage. One amazing feature of the SVAN 979 is that if you disconnect the microphone preamplifier then you can use the instrument for vibration measurements – simply connect up a cable and a vibration sensor .
The SVAN 979 has an extensive range of hardware and firmware add-ons that includes built-in Bluetooth®, windscreen infrared detector, direct connections to GPS module, GPRS or Wireless LAN modem or the totally unique built-in vibration shock sensor that warns the user whenever the instrument itself is exposed to vibrations that may influence the noise measurements.
Two USB connectors allow for the simultaneous operation of USB pen-drives and communication with the computer.
Usage of this number of advanced features at the same time is possible as the instrument has two high-speed digital signal processors. For example, the SVAN 979 is capable of measuring 2 ms steps of time history, logged simultaneously to audio recording (with 48kHz sampling) and real-time frequency analysis. Only the SVAN 979 can meet such a challenge. All data is stored on a microSD card of any capacity (default is 8GB) .
It is also important to note that unlike other brands which recalculate FFT spectrum to octave bands, the SVAN 979 performs frequency analysis in real-time, whether in octaves, third octaves all the way up to 1/12 octaves.
Setting up such advanced measurements can be very complicated but not in the SVAN 979. The intuitive menu structure of this instrument has been designed to make the measurement experience a pleasure.
