SV 277PRO Noise Monitoring Station is an outdoor monitoring system based on SV 977 Class 1 sound level meter.
The SVAN 977 can be easily removed from the case and used as a
hand-held sound level meter.
The monitoring station uses a 4G modem for the remote communication with Internet.
A lead-acid battery is place in an IP 65-rated case for extra protection.
This battery operating time can be easily extended by connecting an external battery or
a solar panel.
The intelligent charging unit enables use of a solar panel without expensive controllers
or heavy batteries.
The case is fitted with very robust, waterproof connectors (military standard) and is
supplied with an IP 65 external power supply.
A light-weight microphone protection kit can be easily installed on a mast with standard mounting threads.
The noise monitoring system provides broad-band results such as Leq, Max, Min and Peak with all standard weighting filters together with an incredible time-history logging feature with two adjustable logging steps. The broad-band results can be recorded in three acoustic profiles which enable measurements to be taken with 3 different filters (e.g. A, C, Z) as well as 3 different detector time constants (e.g. Fast, Slow, Impulse).
