SV104 – Noise dosimeters

SV 104 Noise Dosimeter brings incredible functionality into a compact style instrument. The SV 104 instrument is a revolutionary new approach to occupational health and safety noise monitoring offering voice comments and audio events recording functions which are a new concept in an instrument of this size.

The measurement data is safely stored in the large 8 GB memory and the amazing OLED screen displays information in both text and graphical form and offers excellent visibility even in full daylight.

This personal dosimeter has a robust 1/2 MEMS microphone enabling easy calibration using most commonly available acoustic calibrators. The SV 104 is a cable-free dosimeter and is typically attached to the user’s shoulder, close to the ear using the mounting clips supplied.

The instrument works with Svantek’s specialist health and safety software package, “Supervisor” and is powered using built-in rechargeable batteries or through the USB interface which also enables easy connection between the SV 104 and a PC.

Never before has a noise dosimeter been so accomplished yet affordable, making your measurements more accurate and reliable than ever before.

104A

The SV 104A is a new personal noise dosimeter with a Bluetooth® communication supported by the Smartphone application called Assistant.

For measurements of noise at work in accordance to ISO 9612 as well as OSHA, MSHA and ACGIH standards all settings are configurable in the PC software and can be stored in the dosimeter memory as setup files that can be selected directly from the dosimeter keyboard.

The dosimeter has a very robust MEMS microphone that has a lifetime warranty.  All vibrations that affect noise measurement results are detected by an inbuilt tri-axial vibration accelerometer and are marked in the results time history, so they can be easily excluded from dose calculations.

Additionally, the accelerometer detects if dosimeter is not used by the worker and marks this information in time history.
We have designed the SV 104A to make noise dosimetry measurements easier. Firstly, the voice comment feature replaces necessity of identifying the dosimeter with a different type of stickers. Secondly, a single large measurement range of 53 dB to 141 dB enables measurement in all kinds of working environment.

But mostly, the auto-calibration is what makes the SV 104A easy in use. Once the SV 104A detects a calibration signal, it calibrates automatically saving the calibration data together with the measurement file, before and after measurement.
The list of distinguishing features of SV 104A includes a color OLED display that can be easily read even in a full daylight or in the dark. The user interface is very friendly to use which makes setting up and using the instrument easier than ever.

The user may choose from multiple setup files that can be configured through the included “Supervisor” software. All measurement data are stored in the integral 8 GB memory which provides a vast amount of storage.

104IS

The SV 104IS is the intrinsically safe version of the revolutionary personal noise dosimeter, the SV 104. Both instruments offer a new approach to occupational health and safety noise monitoring presenting features such as 1/1 octave band real-time analysis and audio events recording functions which are a new quality in an instrument of this size.

All results are clearly displayed on the amazing OLED screen which offers excellent visibility even in full daylight or darkness.

This personal dosimeter has a robust 1/2″ MEMS microphone enabling easy calibration using most commonly available acoustic calibrators. The new microphone has a large dynamic range of the 90 dB which allows to measure noise from 60 dBA to 140 dBA.

The long list of microphone advantages includes also the autocalibration feature and TEDS memory that stores the calibration info in the microphone itself. The auto-calibration means performing the acoustic calibration automatically once the microphone is inserted into the calibrator.

The SV 104IS is a cable-free dosimeter and is typically attached to the user’s shoulder, close to the ear using the mounting clips supplied. The instrument works with Svantek’s health and safety software package, “Supervisor”, that provides various tools for data analysis and reporting.

The docking station supports data transfer to the PC through the infrared interface as well as handles the battery charging. Rechargeable batteries of SV 104IS are able to power the instrument for 50 hours.
