The GSS 5GV is a three-axis MEMS vibration and tilt monitor built for structural damage assessment, occupant comfort monitoring, and sensitive-equipment protection – all in one device. It combines an integrated 3G/4G gateway (Wi-Fi optional) with a rechargeable battery base, so it collects, processes, and transmits vibration data continuously without frequent site visits. Configure, install, and manage it remotely, with low-power operation designed to keep maintenance to a minimum.
Autonomous. Connected. Reliable.
Three-axis vibration and tilt monitor
Rechargeable battery base – no more one-time cells to replace
Auto-orientation (Z-axis follows gravity)
On-site gravity self-check – no calibrator or disassembly required
MQTT and FTP connectivity for flexible backend integration
DIN 45669-1 Class 1 precision
At a glance
Structural health monitoring – construction sites, buildings, tunnels, bridges, blast zones, and remote foundations
Occupant comfort assessment – keep vibration within the limits defined by international human-comfort and safety standards
Sensitive equipment protection – safeguard precision machinery, medical devices, and lab equipment from vibration-induced damage
Real-time data in MeasurEye – NTi’s cloud platform for live dashboards, event alerts, and automated reports
Rechargeable battery base extends field autonomy and cuts site visits
The 5GV integrated gateway gives you full control over how your data is collected, named, formatted, and transferred – with flexible connectivity, remote configuration options, and power-efficient operation designed for long-term monitoring.

As a research laboratory invested in supporting communities through real time noise monitoring, I am very happy to exclusively use NTi instruments. Not only are the robust, easy to use, and provide high quality data, the customer service is outstanding and their team will work with you to find the most cost effective and appropriate solutions needed for problems ranging from easy to difficult.

I’ve been using the XL2 for over 15 years for short-term and long-term measurements in all kinds of indoor and outdoor environments all across the country. The meter gets me what I want, when I need it. It’s not only the best value for acoustical measurements, it’s the best tool period. I bet my company and reputation on XL2 results and it has not let me down. You would be crazy not to consider adding NTi instruments to your toolkit.

We at Constructure GmbH use two XL3 sound level meters for noise monitoring during demolition work. We are very satisfied with these highly user-friendly instruments, the online monitoring in the MeasurEye Cloud, the good advice and qualified support. Factory calibrations at NTi Audio are also handled very smoothly and without complications.
