HL48 is a portable, multi-channel, enhancement type 24 digit high professional shallow-layerseismograph.

It adopts 24-digit high-performance analog digital  (A / D) converter at international level. The maximumsampling interval is 20 us.

Eeachchannel independently configured high-precision multi-stall preamplifier, it gainsis set independently for each channel, in order to ensure to gathaer far andnear signal.

WinXPembedded computer systems, hommization interface design, complete easily datagather, processing, storage.

Coloreddisplay with super-high contrast and high brightness, it can clearly display thewaveforms in bright light.

Built-inhigh resolution thermal printer, direct printing waveform acquisition, dateinspection report. Support waveform acquisition automatic batch printing.

Detectorand big line spot testing, full waveform noise monitoring online.

Coverageswitch with built-in all-electronic, improve field construction and explorationefficiency.

Themachine is 1 to 48 channels to Option, the software can be set to 1 to 48seismographs, suitable for different occasions.

Workbandwidth 5KHz, adapted UHF engineering surveys, also for monitoringlow-frequency earthquakes.

Built-inhigh-quality signal source, set day, month, year function to facilitateindustry self-test specification and use.
