TBTGPR series ground penetrating radar is a versatile GPR system offering various detecting combination for application in highway, roads, tunnel construction, paving, buildings, bridges, water conservancy, municipalities or military.
TBTGPR-20 is a portable with cart which specially mainly for tube detecting, which equip with 200MHZ and 600MHZ antenna, to make the detecting more accurate.

TBT Antenna specification:
Antenna types | Center frequency | Pulse width | Depth range | Reference depth | Antenna Applications |
Ground coupling antenna | 200MHz | 5ns | 1~6m |
4m
| |
600MHz | 1.6ns | 0~3m | 1.5m | Roadbed disease detection, Invert quality inspection, utility detection, Water conservancy and hydropower engineering, Geological survey | |
Important note: The penetrating depth of the antenna is tightly related to the conductivity of the medium, the higher the conductivity, the shallower the penetration depth of antenna. The penetration depth will drop sharply in wet clay. The above penetrating depth is under absolute condition of theorotical value. |
