Node-Based Digital Seismograph
◎ Fully integrated node-based digital seismograph with a standard built-in 5 Hz high-sensitivity geophone (5 Hz–150 Hz); optional built-in 10 Hz high-sensitivity geophone (10 Hz–250 Hz), 3.5 Hz high-sensitivity geophone (3.5 Hz–100 Hz), and other models; supports electronic frequency extension;
◎ Built-in 30 Ah high-capacity rechargeable lithium battery; supports high-power fast charging, charging time < 5 hours;
◎ Built-in 24-bit Δ-Σ analog-to-digital converter; sampling rate and preamplifier gain are configurable;
◎ Built-in high-sensitivity GNSS positioning and timing module; supports multi-constellation systems such as BeiDou Navigation Satellite System, Global Positioning System (GPS), and GLONASS; enables microsecond-level precision wide-area system synchronization and supports self-positioning of the instrument;
◎ Continuous satellite timing mode with clock synchronization accuracy better than ±1 μs;
◎ Configurable scheduled acquisition function, allowing flexible setting of acquisition date and duration; supports multiple scheduled acquisition groups;
◎ Built-in signal generator for on-site geophone self-test and calibration;
◎ Built-in BLE and Wi-Fi wireless modules; ground communication distance ≥ 20 m, air-to-ground communication distance ≥ 100 m; supports manual inspection, vehicle-based inspection, and UAV inspection;
◎ Industrial-grade Android PDA supports on-site construction management, device self-test, wireless status monitoring, and real-time waveform visualization; supports precise positioning and retrieval of buried field equipment;
◎ Supports non-interactive mode for rapid automatic acquisition, maximizing field operation efficiency;
◎ High-strength explosion-proof metal enclosure; waterproof rating IP68; flame-retardant and anti-aging; operating temperature range −25 ℃ to 55 ℃;
◎ Compact size, convenient for field transportation and deployment;
