HI  99131 is a portable, microprocessor-
based pH and temperature meter with a
special probe.
The HI 62911 pH electrode has been spe-
cially designed and fully shielded for appli-
cations in plating baths. The titanium elec-
trode body acts like a Faraday cage, and
allows stable readings even in samples
where strong electrical fields are involved.
Moreover, a built-in temperature sensor al-
lows simultaneous pH and temperature
readings and a mini amplifier renders mea-
surements impervious to noise and electri-
cal interferences.

Each meter comes with:

•

  HI 62911 pH/temperature probe

•

 3x1.5V AA alkaline batteries

•
