General information

With zelsius C5 IUF, you have acquired one of

the most up-to-date, modern heat meters cur-

rently available on the market. By this version,

the water volume is determined based on the

transit time method. The measurement accuracy

is based on the measurement requirements of

EN 1434 class 2, optionally class 3. Expressive

symbols in the display and easy menu naviga-

tion make readout simple. Can be operated with

one single button. It is equipped with a long-life

battery made for operation during the initial veri-

cation validity period (5 years) including a re-

serve of at least another year. The meter can be

equipped optionally with a battery lifetime of 11

years.
