Electrical conductivity and pH time-series data generated from the short-term precision experiment to characterize water-quality sondes for the Guidelines and Standard Procedures for High-Frequency Groundwater-Quality Monitoring Station Techniques and Methods Report

This dataset was generated during the precision testing of three water-quality sondes before picking one to use for field deployment of high frequency ground-water quality monitoring. Precision is important because the authors wanted to try and minimize calibration drift corrections between site visits. A laboratory experiment was conducted for the three sondes to simultaneously measure at hourly intervals with a setup of standard solution circulating past the sondes to simulate field conditions. The electrical conductivity experiment lasted 33 hours, the pH experiment lasted 13 hours, and the DO experiment failed (no data).
