en-2

The Elcometer 138 Conductivity Meter can be used in accordance with the

following two test methods:

Ÿ ISO 8502-6 / ISO8502-9

Ÿ US NAVY PPI 63101-000 (Rev 27)

It can also be used in accordance with ISO 8502-11; AS 3894.6-A and SSPC Guide 15.

For IMO PSPC , the surface salts should be measured and recorded. The Elcometer 138 Conductivity

Meter can be used for this.

Incorporating a flat sensor, the Elcometer 138 Conductivity Meter enables

accurate measurement of the conductivity of a solution from a single drop of the

sample.

User Guide

Note: The Elcometer 138 Conductivity Meter measures aqueous solutions. The meter is NOT designed to measure solids,

organic solvents, surfactant, oil, adhesive, alcohol, strong acids (pH: 0 to 2) or strong alkalis (pH: 12 to 14). The life of the

sensor will be extremely short if these substances are measured.

The Elcometer 138 Conductivity Meter is operated using 3 buttons and displays readings and other

information on the LCD screen.

4 USING THE ELCOMETER 138 CONDUCTIVITY METER

Ÿ Never apply undue force when opening the meter (to change the batteries or sensor).

Ÿ Do not drop the meter.

Ÿ The sensor is a consumable part. If it becomes damaged or its performance deteriorates, it will

need to be replaced - see Section 8 ‘Spares & Accessories’ on page en-13.

Ÿ Do not measure samples hotter than 40°C (105°F)

Ÿ Do not exert undue force on the sensor.

Ÿ Do not allow utensils (tweezers, pipette, etc) to touch sensor cell.

Ÿ To ensure the meter is waterproof check that the waterproof gasket is clean, not damaged,

seated properly in the groove and is not twisted or warped.

4.2 FITTING AND REPLACING THE BATTERIES

The Elcometer 138 ConductivityMeter uses dry cell batteries only and is supplied with two CR2032

lithium batteries fitted with an isolation strip. Remove the isolation strip before first use.

2 To reassemble the meter, slide the sensor onto the body

of the meter and push the body and sensor together

gently until sensor retaining clip engages.

Ÿ Do not allow contact with solvents.

To fit or replace the batteries:

Ÿ Do not subject the meter to high temperature or humidity.

1 Place batteries in the battery clips ensuring correct

polarity.

Ÿ Although the product is waterproof, avoid immersing it completely. If the meter is accidentally

dropped in water, take it out and remove the moisture.

4 USING THE ELCOMETER 138 CONDUCTIVITY METER (continued)

Ensure the meter is turned OFF before attaching / detaching the sensor. If the meter is turned ON with

the sensor detached, the battery alarm may illuminate. In this case, turn the meter OFF and attach the

sensor, and then turn the meter ON again.

2 Slide the sensor across the meter so the clip (A) fits into the hole

on the sensor tongue (a), as shown.

When the battery voltage becomes low, the low battery warning indicator will flash. Replace both

batteries immediately.

4.3 ATTACHING & DETACHING THE SENSOR

1 Ensure that the waterproof gasket is clean and undamaged.

2 The sensor can now be completely removed from the meter.

Detaching the sensor:

When removing the sensor, do not let any water penetrate the inside of the

meter. If some moisture remains on the waterproof gasket, very carefully wipe

the moisture off.

1 Lift the sensor tongue tip and slide the sensor slightly away from the meter.

Note: Lithium batteries must be disposed of carefully to avoid environmental contamination. Please consult your local

Environmental Authority for information on disposal in your region. Do not dispose of any batteries in fire.

Attaching the sensor:

Note: Ensure that the waterproof gasket is lying flat and not twisted.

4 USING THE ELCOMETER 138 CONDUCTIVITY METER (continued)

Correct procedure for closing meter after removal of the sensor:

Ensure that the sensor tongue is outside the meter case. If the tongue is inserted between the case and

the connector of the meter, it may damage the connector.

1 Put some drops of the conditioning solution into the measurement cell.

3 Clean the measurement cell with running water.

When using the sensor for the first time or again after several weeks of disuse, perform the electrode

surface treatment procedure as follows:

2 Leave for approximately 10 minutes.

4 Wash the measurement cell with standard solution.

5 Perform the calibration procedure, see Section 4.5 on page en-8.

4 If continues to flash and the ‘Err’ (error message) is displayed, the calibration has

failed. Check that the standard solution conductivity is correct and perform the calibration

procedure again after thoroughly cleaning the sensor. If the calibration failed whilst using

the correct standard solution, the sensor may be damaged and should be replaced, see

Section 4.3 on page en-7.

5 Clean the sensor with tap water and remove moisture.

When using the sensor for the first time or again after several weeks of disuse, perform the electrode

surface treatment procedure, see Section 4.4 on page en-7:

1 Press the ON/OFF button to switch the meter on.

4 Close the protection cover and press the CAL button for over 2 seconds.

is completed, and J stop ﬂashing and illuminate steadily.

4 Bubbles in the solution may cause the measurement to be inaccurate.

4.5 CALIBRATING THE ELCOMETER 138

3 an appropriate amount Open the protection cover and place of the standard

1413µS/cm solution supplied, see Section 8 ‘Spares & Accessories on page

en-13, into the measurement cell avoiding the inclusion of bubbles. Washing

the sensor with standard solution beforehand may provide more accurate

calibration.

2 Press the CAL button until appears on the display.

5 TAKING A READING

• Drop: for a small amount of sample - this is the preferred method for these tests.

1 Press the ON/OFF button to switch the meter on.

The following sampling methods are available:

2 Open the protection cover.

• Scooping: for sampling part of a sample.

4 Bubbles in the solution may cause the measurement to be inaccurate.

1 Put a few drops of the sample into the measurement call avoiding the

inclusion of bubbles.

5.1 BEFORE YOU START

2 Close the protection cover.

5.2 SAMPLING METHODS

• Immersion: for a large amount sample.

4 Ambient air may cause the measurement values to fluctuate. To reduce

environmental interference, close the protection cover.

3 Read the value displayed when appears. illuminates when measured value is stabilised.J J

Note: If a measurement result is out of the speciﬁed measurement range, the displayed measured value ﬂashes.
