Quasi-broadband Nodal Seismograph Built-in 3C 2Hz 260V/m/s Sensors 15s–500Hz |120 Days |4G Real-Time
Introduction
The Broadband UGL3C‑III is a 3‑component quasi‑broadband nodal seismograph for deep lithospheric imaging and long‑term passive monitoring. With a 2 Hz sensor and flat passband from 15 seconds to 500 Hz, it captures both local microseismicity and teleseismic phases. It supports 120 days of autonomous recording or 30 days of real‑time 4G/Wi‑Fi streaming, backed by our proven transmission platform. Designed for ambient noise tomography, deep crustal anisotropy, hydraulic fracturing, and CCS monitoring — the UGL3C‑III delivers the low‑frequency response, endurance, and real‑time connectivity that demanding projects require.
