Bestech Australia introduces a new sound level meter, from Ahlborn, Germany. This digital sound level meter has a measuring level range of 35 to 130 dB. Both A and C frequency weightings can be used. The meter outputs the maximum measured level, while there is an analogue output for connection to measuring devices such as the ALMEMO system also from Ahlborn. The digital sound level meter measures according to IEC651 and ANSI S1.4.
An LCD digital display gives outputs to a resolution of 0.1dB, and display functions include max hold and an alarm function. Analogue outputs can be in both AC and DC form.
The sound level meter has a frequency range of 31.5Hz to 8KHz, and the accuracy of the meter is ±2.0 dB (1000Hz, 94dB). The operating temperature for the sound level meter is 0 to 40°C.
The sound level meter uses a 9V battery which lasts approximately 50 hours, and a 2m cable is included for connection to a data logger (eg. ALMEMO).
