The MiHPT is the combination of the MIP with the HPT. This direct-sensing probe detects volatile contaminants with the MIP, measures soil electrical conductivity (EC) with a standard (MIP) dipole array, and measures HPT injection pressure using the same down-hole transducer as the Geoprobe® stand-alone HPT system. In post-processing the log data with Geoprobe® DI Viewer software, the user is able to estimate hydraulic conductivity (K) and water table elevation, as well as prepare graphical outputs of the log data.
