Product overview
The PTM450 is a photo-colorimetric titration module used with the OPT300 photo-colorimetric probe.
Use the module and the probe to do photo-colorimetric titrations with the Titralab AT1000 series
titrator.
Connect the module to the Titralab AT1000 series titrator with the legacy adapter and follow the
application working procedure to complete a titration. Refer to the AT1000 series titatror and
OPT3000 probe documentation for additional information.
Refer to Figure 1.

Installation
CAUTION
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
English 5

Installation guidelines
• This instrument is for indoor use only.
• The power supply connector on the rear panel must be easily accessible so the power can be
disconnected quickly in case of emergency.
• Keep the instrument away from temperature extremes, including heaters, direct sunlight and other
heat sources.
Install the instrument
D A N G E R
Electrocution hazard. If this equipment is used outdoors or in potentially wet locations, a Ground Fault
Circuit Interrupt (GFCI/GFI) device must be used for connecting the equipment to its main power
source.
WARNING
Fire hazard. Use only the external power supply that is specified for this instrument.
CAUTION
Electrical shock and fire hazards. Make sure that the supplied cord and non‐locking plug meet the
applicable country code requirements.
Prepare the probe and the titration system. Refer to the probe and titration system documentation.
Refer to the illustrated steps that follow.

Operation
D A N G E R
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
Do a titration
Do the steps that follow to complete a titration.
1. Prepare the titration system. Refer to the titration system and the application working procedure
documentation.
2. Make sure that the titration module and the probe are correctly installed and connected.
3. Install the probe on the electrode holder.
4. Connect the titration module to the legacy adapter of the titration system. Follow the instructions
that show on the TitraLab AT1000 to set up the legacy adapter.
5. Select the applicable wavelength on the module 3-position switch: 525 nm or 610 nm based on
your application working procedure.
Usually, select the wavelength that is non-absorbing for the coloured solution at the titration start
then absorbing for the color after the end point. Refer to Table 1 and Table 2.
6. Use the titration system and the instructions on the application working procedure to complete the
titration.

Indicator Non complexed form Complexed form Wavelength
Calmagite Red Blue 610 nm
Eriochrome black T Red Blue 610 nm
Table 2 Wavelength selection based on pH indicator
pH indicator Colour = f (pH) Wavelength
Helianthin red = <3.1
orange = 3.1 to 4.4
yellow = > 4.4
525 nm
Phenolphtalein no colour = <8.3
pink = 8.3 to 10
purple = >10.0
610 nm
Example of a titration curve
In the example, complexometric titration with EDTA at pH = 10 is used to determine the total
hardness of a mineral water. The equivalent point is find with colorimetric detection. The change in
color (wine red to blue) causes a potential jump of 600 to 800 mV and an accurate and reproducible
definition of the equivalent point (standard deviation around 1% on the 3 tests). Refer to Figure 3.

Maintenance
Clean the instrument
Clean the exterior of the instrument with a moist cloth, and then wipe the instrument dry.
Clean the probe
The OPT3000 probe has a low maintenance level. Clean the probe with deionised water and dry with
a soft tissue. Do not use organic solvents to clean the probe. Do not put the probe in organic solvent.
Replace the probe tip only if the mirror is damaged (e.g, scratches). Refer to the probe
documentation for additional information.

Troubleshooting
Problem Possible cause Solution
No output signal The probe is defective.
The connections are not
correct.
1. Remove the probe from the solution and make sure that the
probe transmits light (red for the 610 nm position and green for
the 525 nm position).
2. Examine the titration system connections and power
connections. Make sure that the 3-position switch is set to
525 nm or 610 nm. On the titration system, examine the probe
connection. Disconnect and connect the probe again. Do a
direct measurement to examine the output signal.
There is noise in
the output signal
or the output
signal is not
stable
The probe is not
correctly installed on the
electrode holder.
There is dirt on the
probe mirror tip.
1. Make sure that the probe is firmly attached in the sensor
holder. A small vibration can cause not stable output signals.
2. Make sure that the probe tip is correctly installed in the probe
body.
3. Make sure that there are no unwanted materials in the optical
path of the probe.
The output signal
decreases and
becomes low
There is dirt on the
probe tip.
The optical fibre is
damaged.
1. Make sure that there are no unwanted materials in the optical
path of the probe. Clean the probe.
2. Interchange the two LED Out fibre connections (525 nm and
610 nm).
3. Examine the mirror surface and the optical fibre. Clean or
polish the mirror surface and the optical fibre. Clean the probe.
4. Replace the probe tip.
