OfiTE 130-85 Instruction Manual - Procedure
1. Use the suction bulb to pull the sample into the lucite cell. Empty and
refill the cell several times to thoroughly wet the cylinder walls.
2. Connect the cell assembly to the two terminal posts on the meter. Be
sure the sample fills the area between the two metal posts in the cell. If
the sample is not at room temperature, wait for the temperature of the
sample and cell to reach equilibrium.
3. Depress and hold the black button to calibrate the meter. Turn the
adjusting control knob to set the meter needle to the "ADJ" position.
4. Depress both the black and the red button at the same time, and read
the resistivity of the sample directly from the meter in ohm-meters.
5. Using the thermometer in the cell wall, read and note the temperature
of the sample.
6. Using the nomograph, convert the resisitvity value to concentration of
Chlorides.
Semi Solid Samples (Filter cakes, Mud Solids, etc.):
1. Prepare samples of uniform moisture content.
2. Fill the slot on the outer surface of the cell completely with a semi-solid
sample.
3. Follow steps 2 through 6 in the above procedure.
