Road, Bridge, Tunnel Rock Blasting Vibration Monitor with Triaxial Geophone 

     Blasting vibration Monitor satisfies all the needs of blasting vibration recording happened in the engineering projects of construction, mining, bridge, tunnel, roads and so on. Consultants equippedit as a must for blasting affectionestimation as well as people works in the seismic institutes or related universities.

1--Applications:

                           1.  Blast-monitoring for compliance

                    2.  Near-field blast Analysis

                    3.  Construction Activity

                    4.  Demolition Activity

                    5.  Bridge Monitoring

                    6.  Structural Analysis

                    7.  Underwater blast monitoring

II--Key Features:

    Easy to use   Embedded computer system and backlit LCD make onsite setup and operation quick, easy and  intuitive, even for inexperienced personnel. Italso supports quick view afterwards.

   Triaxial velocity  All 3 speed sensors in one makes cable setting

    Easy- High - A/D resolution A/D resolution reaches to 16 bit, which makes waveform smooth and precise.

    Wide Range Specially designed range from 0.001cm/s to 35.4cm/s covers all the possibilities of blast   vibration recording. Manual operation is not necessary , it adjust automatically .

    Large storage The number of events can be continuallyrecorded is 128 to 1000.The total storage space is 128M which enables user to allocate events.
