SV 104A Personal Noise Dosimeter
The SV 104A is a personal noise dosimeter for occupational noise assessments and hearing-conservation programmes. It is designed to record a worker’s personal noise exposure while reducing the need to interrupt the measurement campaign.
Key features
- Bluetooth® remote control and live measurement preview through the Assistant Pro app.
- Three independent measurement profiles for comparing exposure criteria and time-weighting settings.
- Time-history and exposure results including TWA, dose, LEX,8h, Leq, peak, maximum, and minimum values.
- Built-in triaxial vibration sensor to identify shock, movement, or handling events that may affect the measurement.
- Automatic calibration detection and up to 48 hours of operation for extended campaigns.
- Optional audio recording and octave-band analysis for investigating noise sources and hearing-protection selection.
Applications
- JKKP/DOSH-oriented occupational noise risk assessment support.
- Hearing-conservation programme measurements.
- Noise exposure surveys in manufacturing, construction, utilities, transport, and industrial workplaces.
- Personal exposure studies requiring time-history records for reporting.

What it solves
The SV 104A helps safety teams collect more consistent personal exposure data without repeatedly disturbing workers during a shift. Bluetooth access, measurement profiles, and event detection support better review of questionable or interrupted measurements.

Lifetime MEMS microphone warranty
One reason to choose Svantek over cheaper dosimeters: the official SV 104A datasheet states that the patented MEMS microphone is resistant to accidental mechanical shocks and drops, with a lifetime warranty on the microphone. That protects one of the most exposed components of a shoulder-worn dosimeter and can reduce long-term replacement concern.
Warranty applies to the MEMS microphone; confirm the applicable terms and exclusions with AISYS.
Why buy the SV 104A from AISYS Malaysia?
The SV 104A is not only a dosimeter purchase. AISYS is authorised and trained by Svantek to provide repair and service support for Svantek instruments, helping Malaysian users plan the right configuration, commissioning, maintenance and calibration pathway.
Absolute Instrument Sdn. Bhd. operates a permanent acoustic calibration laboratory accredited under the Malaysia Accreditation Scheme (SAMM 1046) to MS ISO/IEC 17025:2017. The accredited field is acoustic and the published scope specifically includes noise dosimeters, sound level meters and sound calibrators. For noise dosimeters, the schedule lists nominal SPL references of 94 dB, 104 dB and 114 dB, with the stated frequency and electrical-signal ranges and published calibration uncertainty. The current JSM record is available at JSM SAMM 1046. Calibration certificates are issued subject to the documented SAMM 1046 scope.
Lower lifecycle risk with a lifetime MEMS microphone warranty
Noise dosimeters are worn on the shoulder and can be exposed to knocks, drops and accidental mechanical shocks. Svantek’s official SV 104A datasheet states that its patented MEMS microphone is resistant to accidental mechanical shocks and drops, with a lifetime warranty on the microphone. This can reduce concern about one of the most vulnerable and costly components in a personal noise dosimeter.
The lifetime warranty applies to the MEMS microphone, not automatically to every component of the instrument. Confirm the applicable warranty terms, exclusions and service process with AISYS when requesting your quotation.
How the SV 104A helps Malaysian safety teams
- Collect personal noise exposure data across a full shift with up to 48 hours of specified battery operation.
- Use Bluetooth and the Assistant app to review results, control measurements and receive alarms without repeatedly disturbing the worker.
- Identify shock and motion events that may affect the measurement record.
- Use the instrument with measurement workflows based on ISO 9612 and configurable OSHA, MSHA and ACGIH methods, while confirming the required Malaysian assessment method and documentation with the appointed noise risk assessor.

Published SAMM 1046 scope for noise dosimeters
- Nominal SPL reference levels: 94 dB, 104 dB and 114 dB at 1 kHz.
- Acoustic calibration entries covering 31.5 Hz–1,000 Hz and 2,000 Hz–8,000 Hz.
- Electrical signal injection entry covering 79 dB–129 dB and 63 Hz–16,000 Hz.
- Published calibration uncertainty of 0.3 dB or 0.4 dB, depending on the applicable range.
The accreditation applies to the documented acoustic scope; it should not be read as a blanket DOSH-compliance guarantee for every workplace assessment.
