Glossarydimeter. Comparable to previously reported Formazin Turbidity Unit(FTU), and Jackson Turbidity Unit (JTU).Optode: optical electrode.ORP, see Oxidation-reduction potentialOxidation-reduction potential (ORP), also called “redox” potential(from “reducing” and “oxidizing”): Voltage difference at an inertelectrode immersed in a reversible oxidation-reduction system;measurement of the state of oxidation of the system.Parameter node: Node in the Win-Situ or Pocket-Situ Navigationtree, representing a single parameter (pressure, temperature, pH,conductivity, etc.).Parameters node: Node in the Win-Situ or Pocket-Situ Navigationtree, providing a view of all parameters the device can measure.Partial pressure: In a mixture of gases, the pressure a single gaswould exerted if it occupied the entire volume.Pascal: Unit of pressure equal to the pressure resulting from a force of1 newton acting uniformly over an area of 1 square meter.PC: Desktop or laptop computer.PDA (Personal Data Assistant): Generic term for a hand-held personalcomputer.pH: Term used to describe the hydrogen-ion activity of a system; thenegative logarithm of the activity of the hydrogen ions (H + ) in thesolution.Pocket PC: A type of PDA with an ARM processor and Pocket PC(Windows Mobile) operating system.Pocket-Situ: Win-Situ 4 software for supported PDAs.PocketSync for Pocket-Situ: Synchronization utility that runs on adesktop/laptop PC; automatically installs or updates Pocket-Situ ona connected PDA; synchronizes data and other files between thePDA and the PC where Win-Situ is installedPolarization: Application of a direct or alternating current to a sensor.Potassium chloride (KCl): A salt used to make conductivity calibrationstandards.ppm: Part-per-million; equivalent to a milligram per liter (mg/L).Precision: The closeness of agreement between independent testresults obtained under stipulated conditions. A measure of thereproducibility of a method.Pressure: A type of stress which is exerted uniformly in all directions.Its measure is the force exerted per unit area; e.g., pounds persquare inch (psi), newtons per square meter (pascals).Pressure transducer: Instrument or component that detects a fluidpressure and produces an electrical signal related to the pressure.Professional: MP TROLL 9500 model containing memory; able to logdata; accommodates the Basic sensor set.Professional XP: MP TROLL 9500 model with all features of theProfessional model and in addition allows use of the Extendedsensor set.Profiler: MP TROLL 9500 model without memory; must be used with aPC or PDA; accommodates the Basic sensor set.Profiler XP: MP TROLL 9500 model with features of the Profiler and inaddition allows use of the Extended sensor set.Profiling: Taking continuous real-time readings of all enabled parameters.PRT: Platinum resistance thermometer, a type of resistance temperaturedetector (RTD).psia: A pressure unit, pounds per square inch absolute, measured withrespect to zero pressure. All forces detected by the strain gaugeare measured, including atmospheric pressure.psig: A pressure unit, pounds per square inch gauge, measured withrespect to atmospheric pressure. Thus the atmospheric pressurecomponent is excluded.PSU: Practical Salinity Units, based on the Practical Salinity Scale.Pulsing: Periodic low-frequency polarization of a dissolved oxygensensor.Pump test, Pumping test: Aquifer characterization test that involvespumping out a known volume of fluid from a well and measuringthe time of recovery to stable conditions.Quick Cal: Rapid calibration procedure available for the MP TROLL9500 Basic sensors that uses a single solution.Quick Cal solution: A calibration standard of an appropriate chemicalcomposition to calibrate four parameters simultaneously (pH, ORP,Dissolved Oxygen, Conductivity).Quinhydrone: Dark green water-soluble compound, a 1:1 complexof benzoquinone and hydroquinone used as an ORP calibrationstandard when dissolved in pH buffer solution.TROLL 9500 Operator’s Manual150 0095110 rev. 007 01/09
