1.0 SCOPE
The Emcee Conductivity Meter is a
reliable, convenient and inexpensive
instrument for measuring the electrical
conductivity of fuels. The monitor
incorporates all solid-state components
and is completely self-contained. Several
instruments are available for various ranges.
Model Multiplier Range
152-00-0010 X 1 0 – 2,000 pS/m
152-00-0011 X 10 0 – 20,000 pS/m
152-00-0012 X 100 0 – 200,000 pS/m
152-00-0013 X 1,000 0 – 2,000,000 pS/m
152-00-0014 X 10,000 0 – 20,000,000 pS/m
The instrument will display units between 0
and 1999. The conductivity is equal to the
reading times the instrument multiplier and
is reported in picosiemens/meter (pS/m). The
instrument has a simple calibration and zero
check; and indicates when the conductivity
level exceeds the upper range of the meter by
displaying 1--- on the LCD display.

2.0 SIGNIFICANCE
Fuel products such as jet and diesel fuels
which are loaded at high pumping rates,
develop a static charge. The Emcee
Conductivity Meter measures the ability of
the fuel to dissipate that charge.
3.0 DEFINITION
The Emcee Conductivity Meter reads
conductivity in picosiemens/meter which
are equivalent to CU or Conductivity
Units.
4.0 SUMMARY OF METHOD
The Emcee Conductivity Meter uses a probe
consisting of two concentric stainless steel
electrodes. When the probe is immersed in
fuel, a constant voltage is applied to the
electrodes. This results in an electrical
current which is amplified and indicated on
the meter.

5.0 APPARATUS
5.1 The Emcee Conductivity Meter with Fuel
Probe is shown in Figure 1. The meter is a
hand held, battery operated portable
instrument.
5.2 The controls shown in Figure 1 consist
of a measure switch and a calibrate switch.
5.3 Figure 2 shows the location of the
probe calibration number.
5.4 Figure 3 shows the instrument zero
check.
5.5 Figure 4 shows the instrument
calibration check.
5.6 Figure 5 shows a typical fuel test.

5.7 The Accessory Cable Kit shown in
Figure 6 includes a portable reel with
a 50' cable . This kit enables the
operator to connect the probe to the
50' cable for use in a large tank. The
kit also is supplied with a grounding
cable for attachment between the
conductivity meter and tank ground.
6.0 PREPARATION OF SAMPLE
The sample container (preferably a one liter
metal container) should be cleaned with a
solvent and rinsed with the fuel to be
tested. After the sample for test has been
withdrawn, wait approximately two minutes for
charges in the fuel to dissipate.

7.0 TEST PROCEDURE
7.1 Attach probe to bottom connector on
conductivity meter.
7.2 Depress MEASURE switch (M) with probe
OUT of fuel sample. Reading should be 000
+/- 001 in approximately 3 seconds (Figure
4). If reading is outside limits, remove
probe and recheck zero by depressing MEASURE
switch.
7.2.1 If zero adjustment is okay without
probe but not when probe is attached, the
probe should be thoroughly rinsed with
isopropyl alcohol followed by reagent grade
toluene and allowed to air dry before
retesting for zero.
7.2.2 If the reading is outside of limits
with the probe removed, perform calibration
procedure outline in Section 10.0.
7.3 Depress CALIBRATE switch (C) with
probe OUT of fuel sample. After 3 seconds,
reading should be 10 times the probe
calibration number +/- 005 (Figure 4).

SAMPLE
Probe No. = 40
Meter Reading = 400 +/- 5 or 395 to 405
7.4 Insert probe in fuel to upper holes
and depress MEASURE switch. Report displayed
reading times multiplier after 3 seconds for
stabilization. (Due to the polarization of
the fuel sample the apparent reading will
continue to change. Only the reading 3
seconds after depressing the MEASURE switch
is correct).
Note: If a “1” is displayed on the left side
of the display, the conductivity level
exceeds the upper range of the meter.

8.0 PRECISION
The electrical parameters are factory
calibrated to 1% of reading. However, due to
fuel measurement characteristics, the
repeatability and reproducibility limits are
as follows:
PS/M REPEATABILITY REPRODUCIBILITY
50 4 12
100 6 18
150 8 23
200 9 27
250 10 30
300 11 34
400 5% 10%
Limits Applicable at Room Temperature only.
Precision based on ASTM Round Robin test of
standard 0 - 2,000 pS/m meter.
