 Beijing Earth Long Science and Technology is a high-tech enterprise
with more than 30 years history on the development and production
of geophysical exploration instruments and concrete inspection
instruments. Our products are widely used in geological
prospecting, hydrology, engineering survey, structure quality
testing, fields of earthquake monitoring and prediction. We have
passed the ISO 9001:2000 quality management system and as a result,
our instruments and technology have won many national, provincial
and ministerial awards and achievements.
Our concrete non-destructive instruments are DJGW series rebar
locators, DJLC-A thickness gauges, DJUS - 05 non-metallic
ultrasonic gauges, DJCS-05 crack depth test instruments, DJCK - 2
crack widthometers, DJXS-05 corrosion test instruments and DH2000
resilience data processors. These are manufactured by our company,
reaching the leading national technical level, while partial
instrument testing methods and testing precision are up to foreign
advanced level. Our products have been awarded a science and
technology progress prize in 2002 and a DJLC-A national utility
patent.
Our geophysical exploration instruments are MCL series
magnetometers that contain PM-2 high-precision proton
magnetometers, MCL-6 Tri-component magnetometers and MCL-5 fluxgate
magnetometers. Our MCL magnetometer is used for hidden magnetite or
Iron ore exploration on fields/caves. PM-2 high precision
magnetometer is for mineral exploration, iron ore, lead zinc ore,
and copper ore. Geoelectrical prospecting instruments are mainly
DWJ-3B resistivity & IP receiver, DJF series power supply
system (1.5 KW 5KW 10KW three power mode), DD-25 super power
resistivity & IP system, and the DU -2 multi-electrode
electrical imaging system. The power current of supper-power IP
system can reach 25A, exploration depth of 500-800m, effective
geophysical prospecting equipment for deep mineral exploration.
