The following table shows what calibration method must be used for what
type of sensor in connection with what bromination agent
Bromine reagent
Free bromine (HOBr, e.g. by
mixing sodium bromide +
chlorine bleach solution)
DBDMH: 1.3 dibromine-
5.5-dimethyl-hydantoin,
e.g. with trade designation

Albrom 100
BCDMH: 1-bromine-3-chlorine- Suitable for the entire measuring

e.g. with trade designation

Insert the sensor into the DLG III or DGM in-line probe housing, if not
already done (see Assembly, Chapter 6).
Take a water sample for DPD-measurement. Sampling location has to be
close to the installed sensor.
Recommendation: use the sampling tap in the case of the DGM in-line
probe housing (see Figure 2 and Ordering information, Chapter 15).
Determine the bromine content with a suitable DPD-Method ( e.g. DPD).
DPD 4 is especially recommended, when organically bound bromine like
BDCMH (1-Br, 3-Cl-5,5 dimethylehydantoine) is present. In case of high
and constant ratios of free bromine (HOBr), the DPD 1 method is also
suitable.

If bromine is measured as chlorine with a DPD set, multiply the chlorine
value by the factor of 2.25 to obtain the value of bromine.
Input the measured value into the controller according to it's operating
manual (DULCOMETER

After initial installation of the sensor, check the calibration by DPD-
measurement 24 hours later.
The following maintenance intervals based on experiences are
recommended
• swimming pools: weekly
• spa pools (whirlpools): daily
