conductivity measuring device
for ultra-pure water

 
highlights:

GLF100   

 

 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:

   A universal applicability at highest
standards is guaranteed, since the electrode
material is made of stainless steel
(1.4404, 1.4435). 		picture follows within short time!
  • examination of pure and ultra-pure water
  • examination of boiler water
  • functional examination of ion exchangers
