"Measures and instantaneously analyses sound with highly accurate Class 1 microphone"

  • Description

    SoundTEK ST-105 Class 1 Integrating Sound Analyser Meter

    The SoundTEK ST-105 Class 1 Integrating Sound Analyser Meter is an advanced, portable sound analyser capable of measuring A, C and Z as well as F, S and Impulse. It is highly accurate and conforms to IEC 61672 Class 1 accuracy standard. The dual functionality of the device allow it to both take measurements and instantly produce statistical analyses in the 1/1 and 1/3 octave bands which saves time and space by negating the need to transfer data to a separate analysis device. This also makes it perfect for measuring and analysing background noise in the workplace, product noise and environmental noise. The ST-105 has a 24 hour automatic measuring function with adjustable intervals for ease of use.

    Highly accurate readings are provided across a wide range of frequency (10Hz ~ 20KHz) and measurement (25dB ~ 140dB). The dynamic range for a single reading is 90dB and the ST-105 has Fast, Slow, PeakC+ and PeakC time weighting according to the user’s needs. A / C / Z frequency weighting helps locate noise sources and the device boasts a wide range of measurement functions. Sampling frequency is 20.8us (48KHz).

    Results are displayed clearly on a backlit LCD screen alongside a realtime clock with calendar, and the USB Datalogger can store 128 records. In addition, results can be printed out on an optional-extra mini-printer. The multi-language software comes in English, Chinese, Spanish, German and Italian. 

    The SoundTEK ST-105 Class 1 Integrating Sound Analyser Meter measures a truly impressive range of variables and its capacity to analyse results in real time - in addition to a multitude of adjustable settings - makes it an excellent environmental measuring device.
