Ultraslim Logging Sondes for Geothermal Applications
These tools comes with a diameter of only 16 mm, to allow successful testing of in-situ flexible plastic pipe in vertical Geothermal boreholes. They also come with a specially made rope socket and cable head.

Ultraslim Density Sonde
The Geovista Ultra Slim Density Sonde uses a gamma source and detector to measure the variation of local cement density around the U-tube. This allows the location of voids or for quality control of the cement job It has an internal temperature sensor for simultaneous measurements of density and temperature.

Specifications:
