Diurnal Variations Electrical Conductivity of Water Small Stream
2009/10/28
Diurnal fluctuations in electrical conductivity of water have been observed in
a small streBm draining a basin 12 km2 in size. An attempt to explain the cause
of these variations is presented. The t...

Continuous pH, electrical conductivity and temperature measurement at Plynlimon：towards an integrated, reliable and low maintenance instrument system
Water quality Continuous pH temperature measurement electrical conductivity
2009/6/8
Water quality data for the Nant Tanilwyth stream, Plynlimon (an acidic upland stream, the waters of which are of such low ionic strength that measurement is difficult), has been recorded using a new i...
Extension of the measurement range of electrical conductivity by time-domain reflectometry (TDR)
electrical conductivity time-domain reflectometry
2009/6/8
The electrical conductivity (EC) of a medium invaded by TDR sensors can be estimated from the impedance of a TDR reflectogram. Four categories of sensor were tested in salt solutions and the impedance...
