Surface connector: Multi-function vented nylon connector at the sur-
face end of the MP TROLL’s submersible cable; accommodates a
variety of top-of-well devices for communications, networking, and
power supply.
TDS, see Total Dissolved Solids
Tefzel ® : Dupont ® ’s modified ETFE fluoropolymer
Temperature, Solution temperature: Amount of heat present in the
solution in which the instrument is submerged.
Test: Instructions to the MP TROLL’s internal logger for collecting
data; the logged data from one set of instructions.
Test node: Node in the Win-Situ or Pocket-Situ Navigation tree, repre-
senting a single test.
Tests node: Node in the Win-Situ or Pocket-Situ Navigation tree,
providing a view of all tests currently stored in the device memory.
TOC (Top of Casing), see Level—Top of Casing
Torr: A unit of pressure, equal to 1/760 atmosphere.
Total Dissolved Solids (TDS): The amount of dissolved substances,
such as salts or minerals, in water remaining after evaporating the
water and weighing the residue. Calculated from conductivity.
TPU: Thermoplastic Polyurethane, a cable jacket option.
TROLL Com: Communication cable interface between MP TROLL
9500 and a desktop/laptop PC or RuggedReader handheld PDA.
Turbidity: A measure of the transparency of water.
Twist-Lock Hanger: Back end hanger without venting or communica-
tion capabilities; allows use of inexpensive hanging cable while
taking absolute (non-vented) pressure data with a preprogrammed
instrument.
Units: Measurement units; user-selectable in software interface.
Vented cable: RuggedCable with a vent tube that applies reference at-
mospheric pressure to the back of the pressure sensor diaphragm.
Vented pressure sensor, see Gauged pressure sensor
Vertical profile: Characterization of a water column from surface to
bottom (or vice-versa) through multiple real-time readings of the
water-quality parameters of interest taken at varying depths.
Win-Situ 4: Instrument control software for instrument setup, calibra-
tion, profiling, data logging, data retrieval and display.
ZoBell’s: A redox standard solution with a known state of oxidation-re-
duction potential (measured in milliVolts) used to calibrate ORP.
