universal conductivity measuring device
 

 
specialties: GLF 100  

 

 the measuring cells:
  • 3 conductivity measuring ranges
  • low power consumption
  • automatic measuring range change-over
  • min/max-value memory
  • automatic temperature compensation via
    integrated temperature sensor
  • hold function
  • adjustable
 The measuring cells are designed without any compromise.
By the openings of the sensors the electrodes are well washed around
and well-protected against mechanical influences.
The integrated temperature sensors response very quickly.
Compared with more simple electrode types the measurements are
much faster and much more precise.
area of application:  
Graphite used as material for the electrodes
makes the applicability up to 100mS/cm
possible - a must have for seawater analytics!		 picture follows within short time!
  • fresh and sea water aquaristics
  • fish farming / water monitoring
  • drinking water monitoring, etc.
