JW238 Well Temperature Geophysical Logging and Video Surveys Spr /Gamma/Temperature /Caliper Water Well Logger with Automatic Winch
JW238 Temperature Probe
Description
The temperature probe measures temperatures within boreholes, which aids in identifying anomalies resulting from events like fluid influx into the borehole. This tool is commonly employed in hydrogeology to assess the concentration of dissolved ions in aquifers and to pinpoint fluid movements within the borehole.
Feature Highlights
1.
Quick Thermal Detection: The sensor incorporates a PT100 platinum resistor with a low time constant, enabling rapid identification of temperature fluctuations in the strata.
2.
Enhanced Interference Resistance: Demonstrates strong resilience against external interference.
Application Areas
•
Fluid Flow Recognition: Detects fluid flow within open or cased boreholes.
•
Water Table Determination: Maps the location of the water table.
•
Monitoring Water Wells: Perfect for ongoing water well monitoring.
•
Locating Varied Water Quality Zones: Identifies distinct water quality intervals.
•
Logging Geothermal Gradients: Measures geothermal gradients.
•
Implementing Temperature Corrections: Often utilized to apply temperature compensation equations for other logging data.
