Nitrate Probe

Nitrate Probe

The Geovista Nitrate sonde allows for continuous profile of the Nitrate levels in boreholes to be recorded. A measurement of the Dissolved Organic Carbon (DOC) is also made as a quality control as high DOC levels can modify the Nitrate response. The method of operation does not use electrodes in the borehole water, it uses a sealed measurement system that uses the attenuation of UV light at specific wavelengths as the principle of measurement....
QPG Pressure Probe

QPG Pressure Probe

Geovista supply an in-line pressure probe used to log variations in the borehole fluid column. The probe can be run on its own or in combination with other Geovista...
Downhole Monitoring Geophone

Downhole Monitoring Geophone

Geovista manufactures monitoring geophones for use with long term seismic recording in shallow wells. A three axis geophone is lowered into a shallow well and analogue measurements are measured over time. These geophones are generally deployed as part of a field array of geophones connected to a central database for long term monitoring. Please contact us for more...
3-Axis Magnetometer Sonde

3-Axis Magnetometer Sonde

This  sonde measures the strength of the local magnetic filed in three (X-Y-Z) axis. Sensors come in three versions, basic, standard and low noise according to their measurement noise floor. The sonde is also equipped with a two axis (X-Y) accelerometer for the correction of the magnetometer outputs in inclined...
Ultra Slim tools for Geothermal wells

Ultra Slim tools for Geothermal wells

With the increasing use of shallow geothermal wells to provide surface heat and energy, Geovista manufacture ultra slim 16mm logging tools to allow for monitoring, troubleshooting and evaluation of these holes. These include Density, temperature and trajectory. Please see the data sheet for more information.  Ultra Slim Density Probe 16mm OD Detects variations in the cement density around very small diameter casing or tubes Locates zones of insufficient or inadequate cementation Contains a temperature sensor Ultra Slim Temperature Probe 16mm OD Uses an external PT100 sensor Accurate and instant measurements of the temperature profile/geothermal gradient Improves planning and design wells Gives information on seasonal temperature influences Indication of flowing groundwater at site Ultra Slim Pipeline Trajectory Sonde 16mm OD Measures trajectory profile (azimuth and inclination) in non-magnetic pipes Helps confirm the track of the well does not sway away from the property as per many national legal...
