Section 1: System Description
Function and Theory
Geotech's Portable Turbidity Meter offers great precision, repeatability and ease of use in
a low cost extremely robust portable/laboratory instrument. Data points from field sample
events can be stored to memory and transferred to computer or other storage device.
Turbidity Meters provide fluid clarity insight by shining light onto a sample and measuring
the amount of light scattered by suspended particles in the fluid.
The Geotech Portable Turbidity Meter has two light source models to fulfill specific
customer and site requirements:
Model GTW: White Light source, compliant to US EPA method 180.1
Model GTI: Infrared light source, compliant to ISO 7027 standards
Instrument Features
Sample chamber with lid
Data port/ power supply (serial
output, USB to Mini-B cable not
included)
Sealed battery compartment (4x AA
batteries)
IP67 Seal for extension into
hazardous environments
Digital display and navigation keypad
System Components
Economy carry case included,
optional custom foam cut case
available
Lint-free cleaning cloth
2 sample vials
Primary Calibration Standards: 0.10,
20, 100, 800 NTU
Figure 1-1: Instrument Features

Section 2: System Installation & Navigation
Install the battery
1. With a small Phillips screwdriver, remove the battery cover (located on the backside
of the instrument).
Take care to keep the small screws and washers safe when removing the
battery cover.
2. Install four (4) AA alkaline or nickel metal hydride (NiMH) batteries.
Make sure that batteries are installed in the correct orientation.
3. Replace the battery cover.
For optimal seal, we recommend using a torque screwdriver set to 4N-m.
Sample Vial Handling
When placing the vials into the instrument, ensure that
the white line on the sample vial is aligned with the black
arrow on the bottom edge of the instrument’s sample
chamber.
The sample vials must be very clean while calibrating or
doing field readings; no debris or fingerprints should be
visible on the glass. Use a soft cleaning cloth to ensure
clarity before each measurement. Do no store samples
and vial in extreme temperatures or direct sunlight.
Figure 2-1: Replacing the batteries
Handle calibration and sample vials by caps only. Any scratches on the
vials will compromise accurate turbidity readings.

3.3 USB Connection
1. Plug the unit into the computer; wait for device driver to download. Device connection is
successful if an additional COM port is recognized in the Device Manager.
2. Identify a communication port for the connection, look in the computer’s Device
Manager (example: COM2, COM18).
If unsure of which communication port, disconnect and then reconnect the Turbidity Meter
while Device Manager is open and notice which new communication/USB serial port
opens, look under “Ports (COM & LPT)”.
3. Open a serial terminal connection to access the saved data.
Serial terminal programs are available to download from the internet.
For example, “PuTTY” or “TeraTerm” are two serial terminal programs which are
quick and free to download, and simple to use.
4. Configure the serial terminal interface as follows:
Parameter
Value
Speed
19200 bits/sec (baud rate)
Data bits

Parity
None
Stop Bits
1
Flow Control
None
5. To transmit the Data use the menu structure diagram (see Section 3.4) to navigate to
Service > Datalog > Log Transmit.
The display will read, “Wait…” and the serial terminal on the computer will begin the data
log transfer. The data output could be copied and pasted into a data processing program,
such as MS Excel or Word (comma delineated import).
Note: Some variables will appear in the data collected,
"M": Marked
"D": Point where the data has already being transmitted
"E": Clock not adjusted in last transmission

Section 4: System Maintenance
The Geotech Portable Turbidity Meter is designed to be a low-maintenance lab instrument
that can be used in the field.
General cleaning guidelines:
Use a soft cloth with mild soap and warm water to clean the unit.
Clean and dry the sample chamber to ensure no water droplets accumulate on the
lens, as this can affect the accuracy of turbidity readings.
Per each use:
Keep unit clean and free of debris when traveling - build up on sample chamber
lenses could permanently damage the instrument
Calibrate before each use to ensure good data
Seasonal use:
Keep unit clean and free of debris when storing - build up on lenses could
permanently damage the instrument
Remove batteries when storing long term
Ensure a complete calibration is conducted when bringing unit out of storage
Calibration Solutions:
Avoid exposing calibration standards to extreme temperatures. Do not store below
the freezing point, or above 122 °F (55°C)
21
Section 5: System Troubleshooting
Problem: Unit will not turn on.
Solution:
No power to unit:
o Check that batteries are installed and in the correct orientation (+/- polarity)
Problem: Cannot get accurate readings on control samples.
Solution:
Recalibrate unit
Clean lenses inside sample chamber to ensure a clear read
Clean outside of bottles
Check the expiration date on the calibration standards. Expired standards will result in
an inaccurate reading.
If these troubleshooting guidelines have not resolved the problem, contact Geotech
Environmental Equipment at 1-800-833-7958.
