Scope of application: Urine
Scope of application: Industry / Automotive
The following models are particularly suitable for the measurement of the specifi c gravity 
(
sg
)
in urine, the quantitiy of serum 
(
serumproteine
)
 in urine 
(
doping control among athletes
)
, and 
the refractive index.
The following models are particularly suitable for the measurement and determination of AdBlue, 
glycol concentration 
(
ethylene EG, propylene PG
)
, battery fl uid 
(
BF
)
, urea, the freezing point of 
fountain solution 
(
CW
)
 and the refractive index. Furthermore these models are suitable for the 
measurement of thermal exchange systems.
The main scope of applications is:
 · Hospitals
 · Doctor’s surgeries / Physicians
 · Medical training institutions
 · Nursing homes
 · Sports medicine 
(
doping test
)
The main scope of applications is:
 · Automotive industry: Car-workshops and producers
 · Chemical industry
 · Solar industry: Antifreeze monitoring
 · Geothermal industry: Brine-concentration-measurement for ground heat
 · Forestry / Lumbermen
