1. GENERAL
1.1) APPLICATIONS
The Cole-Parmer Ultrasonic Thickness Gauge, Model# UTG-1000 is designed for measuring the
thickness of metals, plastics, ceramics, glass and other ultrasonic wave conducting materials with
two parallel surfaces (top & bottom).
The UTG-1000 can be used in industrial applications to perform precise measurements on various
kinds of materials, parts and components. Additionally, it can be used to monitor various kinds of
pipes and pressure vessels for decreasing thickness due to corrosion and/or erosion.

2
(
The basic principle of the ultrasonic wave in a thickness measurement is similar to that of an
optical wave. The ultrasonic wave pulses transmitted by the probe reach the object to be measured
and circulate through the object. When they reach the interfaces, they are reflected back. The
thickness of the object is determined by precisely measuring the time the ultrasonic wave travels in
the object.

(
• Automatic error correction capabilities
• Automatic linear compensation to improve accuracy (involves the correction of
non-linear errors resulting from the probe).
• Up and down keys allow for quick adjustment of sound velocity and thickness, as
well as fast checking of memory unit.
• Automatic coupling prompt indicates the coupling state: stable/unstable.
• Up to ten different thickness values can be stored(even if the unit is shut off).
• Direct determination of the sound velocity according to the thickness of the
master testing block.
• The sound velocity of up to five different materials can be stored.
• Low battery indicator
• Automatic instrument shut down during idle use period.
• Oil proof keypad provides a longer service life.
4) MEASURING STEPS
4.1) PREPARING FOR MEASUREMENT
Place the probe into the probe socket of the unit (the plug of transmitting end is red) push ON to turn
the unit (see fig 4). After a few seconds, the screen will display the sound velocity used during the last
testing procedure(see fig 5). Begin the measurement.
FIGURE 4: FULL LCD DISPLAY FIGURE 5: SOUND VELOCITY LAST
USED
4.2) ADJUSTING THE SOUND VELOCITY
If the screen currently displays the thickness value, push VEL to enter into the sound velocity mode.
The screen will display the content of the current memory unit for sound velocity. Each time VEL is
pushed, the sound velocity memory unit will change. Five different sound velocities will be displayed in
turn. To change the sound velocity, use the
store the new value.
4.3) CALIBRATION
Each time the probe or battery is changed, a calibration should be performed in order to guarantee
∧∨ to adjust the display to the desired value. Press VEL to
625 East Bunker Ct

(
measuring accuracy. If necessary, repeat the ca
lib
ration several times. Adjust the sound velocity to
5900 m/s (iron) and press ZERO to enter into the a state of calibration
(see figure 7).
FIGURE 7: STATE OF CALIBRATION FIGURE 8: SIGN OF CALIBRATION
Apply the coupling agent to the testing block, which is built into the unit, and couple the probe to the
testing block. At this time, the bar lines displayed on the screen will disappear one after the other until
the screen displays 4.0mm (see fig.8). This indicates that the calibration is over.
4.4) MEASURING THE THICKNESS
Apply the coupling agent to the material to be measured and then couple the probe to the material. This
will begin the measurement, and the screen will then display the thickness of the material (see fig.9).
FIGURE 9: MATERIAL THICKNESS MEASUREMENT
NOTE: when the probe is coupled to the material, a coupling indicator will be displayed. If the coupling
indicator flickers or does not appear, the coupling process is erroneous or incomplete.
Once a thickness measurement has been obtained, remove the probe. The thickness value will remain on the
LCD screen, however, the coupling indicator will disappear (see fig.10)
5) SOUND VELOCITY MEASUREMENT
To measure the sound velocity of a specific material, use a testing block with a known thickness value. Similar to the
measurement of the materials thickness, use a vernier caliper or micrometer to obtain an accurate measurement of the testing
block. Then couple the probe to the testing block until a thickness value is displayed. Remove the probe and use the keypad to
adjust the displayed value to match the actual thickness of the testing block and then press VEL. The sound velocity will be
displayed and automatically stored in the sound velocity memory unit.

6) USING THE MEMORY UNIT
6.1) STORING A THICKNESS MEASUREMENT VALUE
Press and hold VEL, then press ZERO simultaneously to enter into the thickness Memory State.
To display a specific thickness value that has been stored, use the ∧(UP) and ∨(DOWN) arrow pads to look for a required unit.
While measuring the thickness, the measured value can be stored in the unit. Each time a new value is measured, the old value
will be replaced. This unit records the last measurement value. Press VEL to exit the thickness memory mode.

Press and hold VEL to display the unit number of the current thickness memory unit. Use the ∧(UP) and ∨(DOWN)
arrow pads to find the correct unit. If the measurement is done at this time, the new value can be stored in this unit.
Push the VEL key to exit the thickness memory mode.

7) LOW VOLTAGE INDICATOR
If BATT is displayed on the screen, this indicates that the battery voltage is running low and the batteries should be
replaced.
8) AUTOMATIC SHUT-OFF
If the UTG-1000 remains idle for two minutes, the unit will automatically shut off.
9) PRECAUTIONS
The surface of the probe is made of propylene resin and is very sensitive to heavy scratches and rough surfaces.
Therefore, it is recommended to apply only a light to moderate amount of pressure on the probe during testing.
The temperature of the surface of the object to be measured should not exceed 140°F (60°C).
Keep the UTG-1000 clean and avoid exposure to dust, iron chips, carbon particles.
10) ENGLISH AND METRIC MEASUREMENT FUNCTION
The UTG-1000 can obtain measurements in both English and metric unit mode. The following step by step
instructions describe how you can toggle between the two modes.
1) Push ON to turn on the unit. The screen will display the sound velocity used during the last testing procedure.
2) Press and hold “ZERO” button, then press the “ON” button. After a few seconds, the sound velocity and test value
will then switch to the metric unit mode.
3) IMPORTANT NOTICE:
3.1) When the unit is on, if you press and hold only the “ZERO” button for a while, the unit will enter into a state of
calibration.
3.2) In order to obtain the ENGLISH unit mode in the next testing if you have finished the last testing in metric unit
mode and the unit automatically shut off, you have to press and hold “ZERO” button then press the “ON” button
prior to switch on the power when you start the next test.
11) MAINTENANCE
11.1) REPLACING THE BATTERIES
Once the low voltage indicator appears on the screen, the batteries should be replaced.

(
Use the following procedure when replacing the batteries.
* Wait until the unit turns off automatically.
* Open the battery compartment by pressing your thumb down on the cover and sliding it outwards.
* Remove the used batteries and insert new batteries into the compartment, paying close attention to the polarity of the
battery.
11.2) STORING THE UTG-1000
Be sure to clean the cable after each use. Grease, oil and dust will cause the cable of the probe to age and crack.
If the unit is not to be used for a long period of time, remove the batteries to avoid battery leakage and erosion of the
battery compartment.
Avoid storing the unit in a damp or extremely hot environment.
