Chapter A6. Field MeasurementsNational Field Manual for the Collection of Water-Quality Data (TWRI Book 9)6.1 TemperatureRevised By F.D. Wilde This section of Chapter 6 is available as a pdf file: Download a copy of Adobe Acrobat Reader for free. AbstractAccurate temperature measurements are required for accurate determinations of important environmental parameters such as pH, specific electrical conductance, and dissolved oxygen, and to the determination of chemical reaction rates and equilibria, biological activity, and physical fluid properties. This section of the National Field Manual (NFM) describes U.S. Geological Survey (USGS) guidance and protocols for measurement of temperature in air, ground water, and surface water and calibration of the equipment used.
