Operating Principles
The Rugged Conductivity Meter measures and proles
conductivity, temperature, and static water level in wells
and boreholes. Temperature is displayed as degrees Celsius.
Conductivity values are displayed in micro Siemens per
centimeter (µS/cm) with a range of 100 µS/cm to 80,000 µS/
cm. Values represent specic conductivity.
The probe is attached to a measuring tape that is graduated
in feet by 1/100 ft, or in meters by each millimeter.
The conductivity sensor is a four-electrode sensor, congured
as two concentric rings designed to reduce the eects of
fouling. The conductivity sensor is temperature compensated
and uses a temperature coecient of 2%. The compensation
range is 0 to 30° C.
For best results, calibrate the Rugged Conductivity Meter
before each measurement session.
To preserve battery life, the Rugged Conductivity Meter
automatically shuts o after 5 minutes of inactivity. When
the battery is low, “LOW BATT” appears on the display panel.
The meter will continue to operate, but the battery should be
changed as soon as possible.
General Guidelines
Do not scrape the tape against sharp-edged well •
casing. If possible, hang the unit on the well casing,
and position the tape over the tape guide to
prevent damaging the tape.
Avoid entanglement with other equipment in •
boreholes and wells.
Rewind the tape onto the reel after each use.•
Clean the probe tip with distilled water.•
Do not tap or hit the probe to dislodge dirt or mud. •
Soak the probe tip in water to remove trapped dirt.
