GeoSIG's latest seismic recorder offering— nair (rhymes with fire, named after Swiss peak Piz Nair)—is the groundbreaking latest generation of the GeoSIG Measuring Systems with highest performance, excellent operational flexibility and enhanced connectivity. With its optimized installation, operation and maintenance philosophy, nair offers an abundance of features and options. Its user-replaceable modular electronic boards make nair extremely maintainable and future-proof.

It includes an Ethernet connection and optionally a Wi-Fi (b/g/n) module to ensure fast and reliable data transfer. Both wired and wireless network interfaces can be used simultaneously. Its design and efficiency make it ideal for any application requiring seismic instruments. It boasts an impressive 147db (0.02-20Hz), making it suitable for weak-motion precision recording as well. Numerous optimisations within the architecture and the design yields unprecedented performance for seamless and fast execution of all system processes.

The instrument’s software processes data in real time. If triggered by a seismic event, nair calculates a number of Event Parameters and reports them to a data centre immediately. nair is a self-contained instrument and is equipped with numerous power options. The instrument uses an “Intelligent Adaptive Real Time Clock” (IARTC) with self-learning temperature compensation, improving the accuracy of the RTC or TXCO significantly. The IARTC is able to synchronize with GNSS (GPS, GLONASS, BeiDou and Galileo) to provide high timing accuracy. Optionally the unit itself can act as an NTP server as well.

The instrument can be locally connected to a laptop through its ports for configuration, testing or data retrievals. The same functions are available remotely as well. Wired or Wireless Interconnected Network option enables the use of several units together in a time and trigger synchronised manner. There are multiple data storage options available.

nair is fully compatible with existing GeoSIG sensors and can co-exist and co-perform in the same network as the GMS series recorders. The simple upgrade path makes nair "future proof."
