Important Information
CAUTION
The accuracy of the instrument is only valid if the instrument is used in an
environment with controlled electromagnetic disturbances according to DIN 61326.
Wireless devices, e.g. wireless phones, must not be used near the instrument.
Important disposal instructions for batteries and accumulators
EC Guideline 2006/66/EC requires users to return all used and worn-out batteries and
accumulators. They must not be disposed of in normal domestic waste. Because our
products include batteries and accumulators in the delivery package our advice is as
follows :
Used batteries and accumulators are not items of domestic waste. They must be dis-
posed of in a proper manner. Your local authority may have a disposal facility; alterna-
tively you can hand them in at any shop selling batteries and accumulators. You can
also return them to the company which supplied them to you; the company is obliged
to accept them.
Important Information
To Preserve, Protect and Improve the Quality of the Environment
Disposal of Electrical Equipment in the European Union
Because of the European Directive 2012/19/EU your electrical instrument must not be
disposed of with normal household waste!
Tintometer GmbH will dispose of your electrical instrument in a professional and envi-
ronmentally responsible manner. This service, excluding the cost of transportation
is free of charge. This service only applies to electrical instruments purchased after 13th
August 2005. Send your electrical Tintometer instruments for disposal freight prepaid
to your supplier.

General notes
Guidelines for photometric measurements
1. Vials, caps and stirring rods should be cleaned thoroughly after each analysis to prevent
interference. Even minor reagent residues can cause errors in the test result.
2. The outside of the vial must be clean and dry before starting the analysis. Clean the outside
of the vials with a towel to remove fingerprints or other marks.
3. Zero calibration and test must be carried out with the same vial as there may be slight
differences in optical performance between vials.
4. The vials must be positioned in the sample chamber for zeroing and test with the mark
on the vial aligned with the mark on the instrument.
5. Always perform zeroing and test with the vial cap tightly closed. Only use the cap with
a sealing ring.
6. Bubbles on the inside wall of the vial lead to incorrect measurements. To prevent this,
remove the bubbles by swirling the vial before performing the test.
7. Avoid spillage of water into the sample chamber because this can lead to incorrect test
results.
8. Contamination of the transparent cell chamber can result in wrong readings. Check at
regular intervals and – if necessary – clean the transparent cell chamber using a moist
cloth or cotton buds.
9. Large temperature differences between the instrument and the environment can lead
to errors – e.g. due to the formation of condensation in the cell chamber or on the vial.
10. To avoid errors caused by stray light do not use the instrument in bright sunlight.
11. Always add the reagent tablets to the water sample straight from the foil without touch-
ing them with the fingers.
12. The reagents must be added in the correct sequence.
Method notes
• Prior to measurement ensure that the sample is suitable for analysis (no major interferences)
and does not require any preparation i.e. pH adjustment, filtration etc.
• Method specific validation data are available on the Internet (www.lovibond.com) or on
request.
• Different Refill Packs available on request.
• Reagents are designed for use in chemical analysis only and should be kept well out of
the reach of children.
• Ensure proper disposal of reagent solutions.
• Material Safety Data Sheets are available on request

Methods
Notes:
1. Vial cleaning:
As many household cleaners (e.g. dishwasher detergent) contain reducing substances,
the subsequent determination of Bromine may show lower results. To avoid any meas-
urement errors, only use glassware free of Chlorine demand.
Preparation: Put all applicable glassware into Sodium hypochlorite solution (0.1 g/l) for
one hour, then rinse all glassware thoroughly with deionised water.
2. Preparing the sample:
When preparing the sample, the lost of Bromine, e.g. by pipetting or shaking, must be
avoided. The analysis must take place immediately after taking the sample.
3. The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagents
therefore contain a buffer for the pH adjustment.
Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7 before
the reagent is added (use 0.5 mol/l Sulfuric acid resp. 1 mol/l Sodium hydroxide).
4. Exceeding the measuring range:
Concentrations above 22 mg/l Bromine can lead to results showing 0 mg/l. In this case,
the water sample must be diluted with water free of Chlorine and the measurement
repeated.
5. Oxidising agents such as Bromine, Ozone etc. interfere as they react in the same way as
Bromine.

Notes:
1. Vial cleaning:
As many household cleaners (e.g. dishwasher detergent) contain reducing substances,
the subsequent determination of Chlorine may show lower results. To avoid any meas-
urement errors, only use glassware free of Chlorine demand.
Preparation: Put all applicable glassware into Sodium hypochlorite solution (0.1 g/l) for
one hour, then rinse all glassware thoroughly with deionised water.
2. For individual testing of free and total Chlorine, the use of different sets of glassware is
recommended (EN ISO 7393-2, 5.3)
3. Preparing the sample:
When preparing the sample, the lost of Chlorine, e.g. by pipetting or shaking, must be
avoided. The analysis must take place immediately after taking the sample.
4. The DPD colour development is carried out at a pH value of 6.2 to 6.5. The reagents
therefore contain a buffer for the pH adjustment.
Strong alkaline or acidic water samples must be adjusted between pH 6 and pH 7 before
the reagent is added (use 0.5 mol/l Sulfuric acid resp. 1 mol/l Sodium hydroxide).
5. Exceeding the measuring range:
Concentrations above 10 mg/l Chlorine can lead to results showing 0 mg/l. In this case,
the water sample must be diluted with water free of Chlorine and the measurement
repeated.
6. Turbidity (can lead to errors):
The use of the DPD No. 1 tablet in samples with high Calcium ion contents* and/or high
conductivity* can lead to turbidity of the sample and therefore incorrect measurements.
In this case, the reagent tablet DPD No. 1 High Calcium should be used as an alternative.
If turbidity does occur after the DPD No. 3 tablet has been added, this can be prevented
by using the DPD No. 1 High Calcium tablet and the DPD No. 3 High Calcium tablet.
The DPD No. 1 High Calcium should only be used in combination with the DPD No. 3
High Calcium.
* it is not possible to give exact values, because the development of turbidity depends
on the nature of the sample.
7. Oxidising agents such as Bromine, Ozone etc. interfere as they react in the same way as
Chlorine.
