We’ve taken the proven Trillium Compact and made it even smaller and lighter, with no compromise in ruggedness or performance. Trillium Compact Horizon seismometer

This true broadband seismometer is ideal for both shallow direct burial and vault applications, where minimal size, weight and power are essential.

Performance and Versatility

The ultra-portable Trillium Compact Horizon maintains every aspect of the Trillium Compact performance while being the smallest and lightest model ever produced. At just over 1 kg, it is 1/3 of the weight of the direct-bury Trillium Compact Posthole.


The updated design now meets a broader range of use cases, featuring a corrosion proof titanium housing that can be shallow buried up to 10 m depth.

The Result of Continuous Improvement

The innovative Trillium Compact Horizon is the result of continuous research and engineering that has produced ground-breaking advances in performance, size, weight and power in several new instruments, including the Trillium SlimPH and the Trillium 360 GSN for the Global Seismographic Network.


Nanometrics’ commitment to ongoing product development is demonstrated across our instrument portfolio and has resulted in this improved version of our most compact seismometer.

Suite of Low-Power Instrumentation

When paired with the Nanometrics’ Low-Power Pegasus Data Acquisition System, a Compact Horizon station uses less than 400 mW of power. The exceptionally low power consumption significantly reduces battery requirements and extends experiment durations even further.
