Nanometrics Trillium Compact Horizon

Salient Features

The Trillium Compact Horizon is a portable, broadband seismometer designed for high-fidelity ground motion monitoring in both shallow direct burial and traditional vault applications. As the most compact model in the Trillium series, it delivers the full performance of the original Trillium Compact in a smaller, lighter, and more rugged package. With a weight of just 1.1 kg and a corrosion-proof titanium housing, this instrument is ideal for deployments where space, weight, and power consumption are critical.

The Compact Horizon is available in multiple models with bandwidth options down to either 20 seconds or 120 seconds. It maintains exceptional dynamic range, low self-noise, and high sensitivity, making it suitable for a wide array of scientific and engineering applications, from global seismic networks to rapid-deploy field studies. Its IP68-rated construction supports submersion up to 10 meters, enabling reliable operation in wet or flooded environments.

When paired with Nanometrics’ low-power Pegasus data acquisition system, the Compact Horizon forms a fully integrated station with power consumption under 400 mW, making it ideal for long-duration, battery-powered deployments in remote areas.

Installation Tips

The Compact Horizon is designed for maximum flexibility in field installation. Its small form factor and top-mounted connector make it especially well suited for direct burial in shallow boreholes or vaults with minimal modification to existing setups. The titanium housing resists corrosion and supports long-term burial or submersion.

No mass centering is required, and the sensor features digital and physical leveling aids, including a graphical bubble level via Nanometrics’ Centaur GUI and included physical bubble accessories. Precision vertical scribe marks and guide grooves help ensure correct north-south alignment during setup.

For installations in polar or high-latitude environments, the Polar Certified model can operate reliably at temperatures down to –50°C. The sensor is immune to Earth’s magnetic field fluctuations and can be transported without a mass lock thanks to its robust internal design.
