Long-Term Kit for Rion NL-53 (Enhanced)

The Enhanced Long-Term Noise Monitoring kit capitalises on the principal merits of the Rion NL-53: easy and intuitive to use, very low power, single 130 dB range, massive data storage capacity using csv files stored to SD card, reliability and an excellent pre-polarised microphone which is well-suited to long-term external use protected by Rion’s WS-15 microphone protection.

6 days battery life using one 12v, 12 Ah battery or 12 days when deployed with 2 (option). This is a very conservative estimate of the battery life based upon the power consumption with third octaves and audio recording running continuously. Used as a broadband meter 10 days per 12V, 12 Ah battery would be a reasonable expectation with the display switched off.

The meter and batteries are deployed in a weather-resistant pelicase.

The weather protected microphone assembly is mounted on a 1.2 metre pole attached directly to the pelicase making the system easy and rapid to deploy because no further arrangements are necessary for mounting the microphone.
