SVANTEK SV 104A – Personal Noise Dosimeter
The SV 104A personal noise dosimeter is a new version of the iconic SV 104 noise dosimeter. The new model is now equipped with 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.
The standard SV 104A kit includes ST 104A shock resistant MEMS microphone, windscreen with a steel mounting thread and a USB cable for communication with PC. The instrument has an inbuilt 8 GB memory and a long-range Bluetooth interface for communication with Assistant application. Each SV 104A has its factory calibration certificate, and LIFE-TIME WARRANTY card on MEMS microphone. The standard kit also includes license for PC software and Assistant application for smart-phones.
