Geophysical instrument engineering seismograph
Geopen Inc offers a compact engineering seismograph designed for shallow reflected and refracted wave surveys. The unit provides 24 simultaneous channels with a selectable sampling interval from 25 µs to 10 ms. Its bandwidth covers 0.1 Hz to 5 kHz and the analog filter can be programmed for low‑cut (10‑200 Hz), high‑cut (500‑2 000 Hz) and mains‑line (50/60 Hz) rejection. Onboard processing uses a 500 MHz Intel Pentium CPU, 118 MB RAM and a 10 GB hard drive, delivering data via USB in SEG‑Y, SEG‑2 or proprietary formats.
The chassis measures 330 × 180 × 100 mm and weighs 4.5 kg, with a water‑tight keyboard and mouse buttons suited for field conditions. A 24‑bit A/D converter gives a precision of 1 µV rms input noise at a 2 ms sampling rate, while harmonic distortion stays below - 114 dB. Cross‑channel interference exceeds 80 dB, ensuring clean multi‑channel records typical of modern seismic acquisition rigs. Compared with standard engineering seismographs, the 24‑channel layout and portable size place this model in the high‑density, field‑deployable segment.
The instrument is used by geophysical contractors, research laboratories and infrastructure developers for shallow wave speed testing and transient Rayleigh‑wave surveys. Buyers can request the system with a water‑tight packing and verify the USB data transfer capability before shipment. Shipping terms, incoterms and payment conditions are to be confirmed directly with Geopen Inc. Prospective importers should also ask for the factory‑issued calibration certificate and a functional self‑test report.

Sourcing Geophysical instrument engineering seismograph from Geopen Inc - China Import Guide
Before placing an order, importers should obtain a detailed datasheet confirming the 24‑channel configuration, sampling interval range and noise specifications. Request a factory calibration certificate and a functional self‑test report to ensure the unit meets the advertised performance. Verifying the water‑tight keyboard and USB port integrity is also advisable for field durability.
Logistics for this Chinese‑origin equipment typically involve sea freight from the Tianjin or Shanghai ports, with lead times of several weeks depending on the chosen incoterm. Buyers should discuss whether the supplier can ship under FOB, CIF or DDP terms and agree on payment methods such as TT or LC, keeping in mind the zero response rate shown in the profile. Confirm packaging details, especially the protective packing mentioned, to avoid damage in transit.
Quality assurance should include a pre‑shipment inspection by a third‑party agency to check channel functionality, noise level and the self‑test results. Request the inspection report together with the calibration certificate and any available test logs. Upon arrival, verify the unit against the specification sheet and conduct a quick field test before integrating it into larger survey operations.
