Trilium Compact Posthole 20 SCategories: Seismometer
The Trillium Compact Posthole is a small, ruggedized, waterproof member of the industry-leading family of Trillium seismometers. The Trillium Compact PH is rugged enough to be buried directly in an ice shelf, light enough for easy portability on a volcano, and intuitive enough to be deployed easily up to 300 metres.
Don’t let your seismometer limit you. The Trillium Compact Posthole is a small, ruggedized, waterproof member of the industry-leading family of Trillium seismometers.
At just 3.3 kgs (or just over 7 lbs) and with the installation convenience comparable to a geophone, the Trillium Compact PH is the obvious choice for those who don’t want their experiments to be limited – by a complex deployment of bulky instrumentation, by the overburden, by the effects of moisture, by thermal instability, by high power consumption or by installation technique.
