This makes them useful for the analysis and detection of teleseismic earthquakes as well as techniques involving ambient noise. However, they are also well-suited for measuring high-frequency energy, limited only by the Nyquist frequency of the [[data logger>>doc:Instrumentation.ANU LPR-200.WebHome]]'s sampling rate. The downside to broadband sensors is usually their cost, size, and fragility relative to short-period sensors. 8 8 9 -* staff and facilities available at your institute 10 -* shipping method (air, sea, road/rail) 11 -* access for inspectors en route (e.g., customs or dangerous goods). 9 +== Nanometrics == 12 12 13 - Inmost instances,we providedimensionsfortheborrowertoquote andbook freightdirectlywiththeirpreferredcarrier.

The Trillium Compact 120, Trillium Compact 20, Trillium Compact Posthole, and most recently, the Trillium Compact Horizon. These seismometers are ideal for long-term deployments of multiple months. All of these seismometers are compatible with the LPR-200 and TSAWR loggers and are designed for low energy consumption. 14 14 15 - Directionsforreturn freight willbe provided with yourSupply Agreement.13 +=== Trillium Compact 120 === 16 16 17 - ----15 +The Trillium Compact 120 has a recording range between 120 seconds and 100Hz. 18 18 19 - =Arrive clean, leave clean =17 +What info? 20 20 21 - Planahead toensure your teams have the time andtools they need to avoid movingorganic material between sites and regions.
