TEMPOS RK-3 thick single needle (6 cm)
Measure the thermal properties of the hardest materials
The TEMPOS RK-3 needle is explicitly designed for use in hard materials like rock or cured concrete, after using a 4-mm (5/32-in) rotary hammer bit (included in the RK-3 Rock Sensor Package) to drill a pilot hole in the material.
The RK-3 Rock Sensor Package also includes thermal grease, which we recommend for improved thermal contact with rock and concrete.
