Import Dshq6b Engineering Seismograph — Buy in Bulk from Supplier in China

The Dshq6b engineering seismograph is a compact, 6-channel seismic acquisition system designed for urban geophysical surveys and shallow subsurface investigations. Built on a Windows XP platform with a military-grade PC104 controller, it supports surface wave, refraction, shear-wave, and high-density seismic imaging methods. The system features a floating-point 24-bit A/D converter and a noise floor below 1 μV, enabling high dynamic range measurements in noisy urban environments where cultural interference is common.

The instrument allows flexible channel configuration with optional 1, 2, or 3-channel modes, making it suitable for small-scale projects or mobile survey teams. Preamplifier gain can be selected in 100x, 10x, or 1x settings, and the time delay range extends from 0 to 9999 ms, supporting deep penetration surveys with controlled excitation timing. Its compact size (390 x 270 x 190 mm) and 9 kg weight make it ideal for transport in confined urban spaces. The system includes a touch screen interface and handwriting tablet support for field data entry without requiring external peripherals.

This model is commonly used by municipal engineering consultants, foundation testing firms, and environmental surveyors for applications such as pile integrity testing, subsurface void detection, and blasting vibration monitoring in cities. Buyers typically include local geotechnical contractors in China and neighboring countries with limited budgets for multi-channel systems. Trade terms are generally FOB Zhuhai, with packaging in rugged plastic cases. MOQ and lead time are not specified and must be confirmed directly with the supplier. Data output is in SEG-2 format for compatibility with standard analysis tools.

Zhuhai Dshing Import & Export Co., Ltd. is a registered supplier based in Nanping, Zhuhai, with a physical address at No.333 Xianqiao Road. The company is classified as an imported supplier with harbor-level trust verification, indicating compliance with export documentation protocols. There is no public information on manufacturing capacity, staff size, or revenue. The listing presents the company as an exporter of the Dshq series, but does not claim ownership of the design or production of the seismograph hardware.

The supplier’s response rate and average response time are both recorded as zero, suggesting no active engagement with buyers on the platform. This does not reflect on product quality but may indicate limited customer service infrastructure. No certifications such as CE, ISO, or RoHS are mentioned. Buyers should request documentation on product origin, calibration history, and after-sales support before committing to purchase, as these are not guaranteed in the listing.
