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.

Product components

Make sure that all components have been received. Refer to Figure 2. If any items are missing or

damaged, contact the manufacturer or a sales representative immediately.

Note: The power adapter is not supplied with the instrument. The power adapter is sold separately. Refer to

Replacement parts and accessories on page 10.

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.

6 English

English 7

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.

Table 1 Wavelength selection based on indicator

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.
