FTN02 Field thermal needle system performs accurate on-site (field) measurements of the thermal resistivity and thermal conductivity of soils. Measurements with FTN02 comply with ASTM D5334 and IEEE 442 standards. The system is specifically designed for surveys that require measurements from the surface down to a depth of 1.5 m. Due to the long and thin lance to which the sensor is mounted, the insertion of the thermal needle into the soil requires just a small-diameter access hole, typically made using a ground drill. Using a lance rather than digging trenches saves time. FTN02 is operated and powered from the hand-held control and readout unit CRU02.

TNS02 efficiently and accurately performs on-site (field) as well as laboratory measurements of the thermal conductivity and thermal resistivity of soils. The system is a combination of our FTN02 and MTN02 systems. Measurement with TNS02 complies with ASTM D5334 and IEEE 442 standards. It is designed for optimal flexibility. TNS02 includes two different needles; one on a short insertion tool for use in the laboratory, the other mounted on a long lance for use on-site. The control and readout unit, CRU02, is shared between the two (on-site and laboratory) needle models.
- Efficient and accurate measurement of thermal conductivity and resistivity of soils
- Measurements both in the field and in laboratory environments
