Turbidity and Total Suspended Solids (TSS) are two of
the most important indicator parameters for water
quality monitoring.
The new Turbimeter Plus has been developed with
leading water utility companies and provides the ideal
testing platform for drinking water, wastewater and safe
water monitoring.
• Fast and reliable results within 5 seconds
• Specifically designed for field use with storage for
1000 results and battery power for approximately
10,000 tests
• Unique Quadoptix technology with four individual
measurement points for increased reliability
• Variety of operating and reading modes including
TSS, Average and Continuous Capture
• USB connectivity for power, downloading data and
installing software upgrades
• IP67 certified with a waterproof USB socket
1
Introduction
The Palintest Turbimeter Plus utilises QuadoptiX™
technology for turbidity measurement.
QuadoptiX technology uses two independent sources
and two independent detectors to provide four entirely
autonomous measurement systems, allowing multiple
validation of all results for greater accuracy.
Turbidity measurements are carried out by analysis of
light scattered at 90° to the incident light (nephelometric
measurement) at levels below 40 NTU. Above 40 NTU
the recommendation is to measure also at 180° to
'compensate’ the 90° readings.

Please read the entire manual prior to setting
up or operating this equipment.
Make sure that the protection provided by this
equipment is not impaired, do not use this
instrument in any manner other than specified
in this manual.
The instrument is IP67 certified, including the
USB port, however it is recommended that the
Turbimeter Plus is clean and dry before use.
Review the ‘Care and Maintenance’ section for
recommendations on best practice.

The Turbimeter Plus is supplied with batteries that will
provide power for approximately 10,000 tests. The
instrument can also be powered through the USB port.
An indication of remaining battery life is displayed on
screen with the battery status icon. To save power, the
instrument will switch off after five minutes of inactivity.
When battery life is very low, the instrument will display
the following error messages:

Replacing batteries will not lead to settings
or calibration data being lost. All user data
is retained.

When replacing batteries, ensure the gasket seal
is correctly fitted to maintain the IP67 rating of
the instrument. A spare gasket is included with
your instrument and should be used if the gasket
looks to be damaged, stretched or twisted.
Ensure the sample tube cap is
in place during measurement.
The following guidelines for sample handing should be
followed to ensure accurate and consistent results are
obtained
.
Use only clean sample
tubes and rinse with sample
before use.
Remove all marks and
fingerprints from the sample
tube before measuring
.

should be discarded.
Remove bubbles from sample

at an angle and rotate.
To reduce the effect of scratches
on the glass, place a drop of
silicone oil onto the

Technical Support and Warranty
Error Messages
The Turbimeter Plus is IP67 compliant, so
contact with water will not damage the internal
components. It is recommended that the instrument is dry
prior to use. The USB connector and cable must be dry before
use. The instrument does not require regular cleaning for normal
operation. If required, clean the instrument with a dust and lint
free cloth. Do not clean the Turbimeter Plus with solvents or other
cleaning agents.
Sample Tube
The sample tube should be clean and dry prior to insertion into
the sample holder. Lint free polishing cloths are provided for
this purpose. Small scratches on the sample tube can cause
discrepancies in the test results. To reduce the effect of these
scratches, place one drop of silicone oil onto the tube and wipe
across the glass using the lint free polishing cloth. Sample tubes
should be rinsed with distilled water. Use a soft cloth to dry the
sample tube. Do not air dry the sample cells as this may leave
marks or residue on the surface.
Indexing a Tube
Indexing is used to identify the optimum orientation of the sample
tube, particularly when taking measurements of low turbidity
(<1NTU). Our continuous capture mode has been designed for this
use, instructions shown on pages 17.
Check and Calibration Standards
SDVB turbidity standards are provided in the kit. Do not
use the standards after the stated expiry date. Exposure to
freezing temperatures can affect the quality of the standards. Do
not store the standards at temperatures close to 0°C. The use
of a heat pad is recommended for shipping. Replacement SDVB
turbidity standards are available from Palintest and authorised
distributors.
Care and Maintenance

45
When storing the unit in the case, always keep
a clean, dry tube with its cap on in the optical cell.
Ensure all glassware is kept clean and dry before storage.
If there is water in the optical cell this needs to be
removed before replacing it in the case. (Be especially
careful that dirt is not wiped into the optical windows –
consider using a cotton bud or similar to remove water
without touching the sides of the optical cell)
Do not keep damp cleaning cloths inside the case.
Be especially careful when changing the batteries to
place the sealing gasket over the raised flange on the
battery compartment cover before replacing.
If any moisture gets into the case keep the lid propped
open until it dries out thoroughly.
Never attempt to wipe the recessed optical lenses or the
areas around these recesses. Dirt or debris pushed into
the recessed window will cause erroneous readings or
error messages to be displayed.
