Nanometrics Trillium Horizon 360 Very Broadband Seismometer
TRILLIUM-HORIZON-360
The Nanometrics Trillium Horizon 360 is the newest instrument in the Horizon series, with a lower noise floor and a lower corner frequency than the Horizon 120. Its response is flat to velocity from 360 seconds to 136 Hz, with a dynamic range of 169 dB at 1 Hz.
In-Depth Overview
The Nanometrics Trillium Horizon 360 is the newest instrument in the Horizon series, with a lower noise floor and a lower corner frequency than the Horizon 120. Its response is flat to velocity from 360 seconds to 136 Hz, with a dynamic range of 169 dB at 1 Hz.
Like the Horizon 120 it is designed for shallow direct burial, vault or pier installation, with a top-mounted connector for vault work. The stainless steel housing is rated IP68 and NEMA 6P for prolonged immersion to 10 m. Power consumption is 250 mW typical, about half that of the previous generation.
The Horizon 360 is intended for permanent national and regional network stations and for instrument pools that need observatory-level long-period performance in a sensor that is still practical to deploy.

CASCADIA-COMPACT-POSTHOLE
Nanometrics Cascadia Compact Posthole Seismometer & Accelerometer IP68
The Nanometrics Cascadia Compact Posthole Seismometer and Accelerometer is a professional-grade, integrated seismic sensing solution designed for comprehensive ground motion monitoring. Featuring a Trillium Compact broadband seismometer combined with a Titan strong-motion accelerometer in a single robust IP68-rated posthole housing, this device is engineered to accurately capture a wide spectrum of seismic signals—from microseismic events to intense ground shaking beyond broadband clip levels. Its seismometer module options include 120-second and 20-second natural period versions, offering a flat velocity response up to 108 Hz, ideal for precise frequency analysis in environmental seismic monitoring, building acoustics, and noise vibration harshness (NVH) testing. The accelerometer complements this with a DC to 430 Hz frequency range, electronically selectable full-scale measurement ranges from ±0.25 g to ±4 g, and an industry-leading dynamic range of 166 dB at 1 Hz, making it suitable for strong-motion monitoring and structural health diagnostics. This dual-sensor integration reduces installation complexity and cost by sharing a single borehole, guaranteeing co-located data sampling for enhanced accuracy and reliability. The IP68 rating supports prolonged immersion up to 300 meters, suitable for challenging field conditions including environmental and geotechnical monitoring. Applications of the Cascadia Compact include seismic event detection, structural vibration monitoring in civil engineering, automotive and aerospace NVH testing, manufacturing quality control, and building acoustics assessments. It complies with international standards to ensure precise and reliable measurements, supporting regulatory and research requirements. Target users include geotechnical engineers, seismic researchers, environmental scientists, consulting firms specializing in structural and acoustic monitoring, and industry professionals requiring professional acoustic and vibration measurement equipment. Placid Asia provides Nanometrics instruments across Thailand and Southeast Asia on a quotation basis.

CENTAUR-GEN5
Nanometrics Centaur Gen5 Seismic Data Logger, 3, 6 or 8 Channels
The Nanometrics Centaur Gen5 is a seismic data logger for permanent and semi-permanent stations, running the StrataOS operating system. It digitises, processes, records and streams data from broadband seismometers, accelerometers and other sensors in one low-power, IP68-rated unit. Three models are available: 3 channels for single-sensor stations, 6 channels for the common pairing of a broadband seismometer with a strong-motion accelerometer, and 8 channels for multidisciplinary stations that combine seismic with other analogue and digital sensors. Resolution is selectable from 24 to 32 bits, with sample rates up to 10,000 sps on the high-resolution channels and a dynamic range of 146 dB. Data are recorded to 8 GB internal storage, expandable to 256 GB, with SD-card archiving in MiniSEED, and streamed by SeedLink, CD-1.1, QSCD20 or Nanometrics NP. Timing is by GNSS or PTP with an accuracy better than 5 µs. Security features include OpenVPN and HTTPS. Placid Asia supplies Nanometrics instruments in Thailand and the region on a quotation basis.
PEGASUS
Nanometrics Pegasus Portable Seismic Digitiser, 3 or 4 Channels
The Nanometrics Pegasus is a portable seismic digitiser built for temporary deployments where size, weight and power decide how many stations a project can afford. It weighs 650 g and is rated IP68 for immersion to 1 m. Pegasus is available with 3 or 4 input channels, sample rates from 1 to 1000 sps and a typical dynamic range of 142 dB at 20 sps. Timing is by multi-constellation GNSS (GPS, GLONASS, BeiDou, Galileo, QZSS), with better than 5 µs accuracy when GNSS is always on and duty-cycled operation to save power. Data are recovered over USB-C: a month of data downloads in under 10 seconds, ready for processing. Pegasus pairs with the Trillium Compact family of seismometers and forms the core of the Pegasus Quick Deploy Kit. Placid Asia supplies Nanometrics instruments in Thailand and the region on a quotation basis.
PEGASUS-QUICK-DEPLOY-KIT
Nanometrics Pegasus Quick Deploy Kit, Portable Broadband Station
The Nanometrics Pegasus Quick Deploy Kit is a complete, standalone broadband seismic station in a briefcase-sized IP67 case. It combines the Pegasus digital recorder with a Trillium Compact Horizon seismometer, which together draw less than 400 mW, and the complete kit weighs under 10 kg. The kit reduces the time and overhead of packing and makes transport straightforward, so a field team can carry, place and start a station with little preparation. The station records unattended, and data are recovered from the Pegasus over USB-C at the end of the deployment. Typical uses are rapid response after a significant earthquake, short site surveys, teaching and training, and adding temporary stations to an existing network.
