Center Technologies Model 390 Data-Logging Sound Level Meter (SLM)

Monday, 03 March, 2014 | Supplied by: TRIO Test & Measurement



The Center Technologies Model 390 Data-Logging Sound Level Meter (SLM) features a 100 dB dynamic range covering 30 to 130 dB without the need to change ranges either manually or automatically. Other SLMs cover this range of sound levels in 2, 3 or even 4 ranges, requiring each range to be calibrated before use for optimum accuracy and switched when moving between differing level measurements.

Main advantages of the device include: unattended logging from 30 to 130 dB without operator intervention; single-range operation means less work to calibrate before use; single-range operation removes errors in range switching; and single range removes latency found in multirange, auto-ranging models.

The device can log 32,000 readings to memory. These results can be downloaded to a PC via the included PC software and interface cable. The included software can log measurements in real time directly to the PC, graphically displaying sound level history.

Compliant to IEC61672-1 Type-II, the device has an ‘A’ weighting filter as required for determining risk of noise-induced deafness. ‘C’ weighting is also available, as are fast and slow measurement times.

Suitable for workplace OHS/WHS representatives and consultants, compliance officers, etc, and everywhere sound level is measured and/or recorded, the device also has optional sound level meter calibration.
