Pocket-size pH-meters PHEP4 / PHEP5

  • Replaceable electrode.
  • Simultaneous display of pH and temperature.
  • Automatic temperature compensation.
  • Automatic calibration by 2 buffer values stored in memory.
  • Range : 0,00 to 14,00 pH ± 0,05 pH.

Pocket-size pH-meters Testo 206

The pH Testo 206 sensors use an electrolyte gel as a reference to measure the pH instead of the traditional liquid electrolyte.

This allows the use of a perforated diaphragm instead of the
microporous membrane with delicate maintenance and limited lifespan.

  • Universal use for almost all the applications.
  • Robust sensor, without maintenance and not very prone to dirt.
  • Unique design allowing to limit the breaking of glass.
  • Combined measure of pH and temperature (CTN sensor).
  • pH range : 0,00 to 14,00 pH ± 0,02 pH.
  • Temperature : 0,0 to 60°C ± 0,4°C.
 
      

pH-/°C meter HI 991001

Measures and displays simultaneously the pH and the temperature.

  • Automatic temperature compensation.
  • Simplified calibration with 2 series buffer values stored in memory.
  • Stability indicator.
  • pH range : -2,00 to 16,00 pH ± 0,01 pH.
  • Temperature : -0,5 to 105°C ± 0,5°C.
 
   

Laboratory pH-meter HI 2210-02
