Import Dshq 48 High Resolution Seismograph — Buy in Bulk from Supplier in China

The Dshq 48 high resolution seismograph is a multi-channel seismic acquisition system designed for engineering and geophysical surveys, built on the foundation of the Dshq24 platform and optimized for Chinese operational conditions using a Windows XP environment. It supports simultaneous sampling across 48 channels with a minimum interval of 31.25 microseconds and up to 10 microseconds for single-channel mode, enabling high-resolution data capture for shallow to deep subsurface investigations. The system integrates a 24-bit A/D converter with automatic anti-alias filtering and digital wave filters adjustable via software, ensuring precise signal fidelity across frequencies from 0.1Hz to 4kHz.

The instrument is engineered for field durability and operational flexibility, supporting excitation sources including hammer, electric spark, and explosive triggers. It enables reflection, refraction, surface wave, shear-wave, and high-density seismic imaging methods, with built-in overlaying capabilities for 12- and 24-channel configurations without external hardware. The preamplifier gain can be selected in 6-channel groups at 64x, 16x, 4x, or 1x, and the system includes a self-checking diagnostic module that generates automated reports on geophone integrity, line continuity, and noise levels. Its TFT display, membrane keyboard, and touch screen support field operation, while USB and Ethernet interfaces allow data transfer and remote control.

This seismograph is primarily used in civil engineering, transportation infrastructure, and resource exploration projects including bridge pile testing, slope stability assessment, groundwater mapping, and urban blasting vibration monitoring. Buyers include geotechnical survey firms, municipal engineering departments, and mining exploration teams operating in China and Southeast Asia. The unit ships with SEG-2 and SEG-Y compatible data formats and includes processing software for reflection, refraction, and surface wave analysis. Trade terms are typically FOB Zhuhai Port, with packaging in industrial-grade shock-absorbing cases. Lead time and MOQ must be confirmed directly with the supplier, as these are not disclosed in the listing.

Zhuhai Dshing Import & Export Co., Ltd. is a supplier based in Nanping, Zhuhai, with a registered address at No.333 Xianqiao Road. The company is listed as an imported supplier with harbor-level trust verification, indicating compliance with export documentation standards. There is no public information on company history, employee count, or annual turnover. The listing confirms the company acts as a distributor or exporter of seismic instrumentation, specifically the Dshq series, but does not claim manufacturing capability or in-house R&D.

The supplier's response rate and average response time are recorded as zero, suggesting limited or no active customer communication on the platform. This does not indicate product quality but may reflect operational practices. The product is presented as a technical instrument developed for Chinese regulatory and field conditions, with no mention of international certifications such as CE or ISO. Buyers should verify the supplier’s export experience and after-sales support capacity before placing orders.
