General Description And Intended Use - Hanna Instruments HI99131 Instruction Manual

The HI99131 portable pH meter, together with the
HI629113 pH probe, are designed specifically for pH
measurements in plating baths. Plating Baths can vary from
acid to neutral to alkaline with many different chemical
formulations used. The common necessity is the fast and
accurate measurement of pH to ensure that additives
and chemicals are working properly to provide even and
consistent plating.
The HI99131 pH meter is a portable, lightweight meter with
two button operation that is simple to use. It is delivered
with a rugged pH electrode protected by a titanium body
that functions properly in an applied current field thus per‑
mitting the flexibility of bringing quality pH measurements
directly the operation.
HI629113 pH electrode has been specially designed for
applications in plating baths. The titanium electrode 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 allows simultaneous
temperature compensated pH and temperature readings and
an integral pH sensor preamplifier provides measurements
impervious to noise and electrical interferences.
