Long Life 12pH Online PH Electrode With KCl Solid Gel Double
The accuracy of the pH electrode depends on two key components: the
glass bulb and the junction. The slope, response time and
measurement error of the pH electrode are usually determined by the
structure, material and processing technology of the two
components. The ASP300 series pH electrode developed and produced
by Delfino uses a low-impedance hemispherical glass bulb, which has
a good response to H+ in the solution. The junction is made of
large-area annular porous PTFE, which has a higher flow rate, is
not easy to be clogged, and is easy to clean.

KCl solid gel
A British 1 NPT of the head and the tail for each install thread；
Insert depth 100(including cleaning plug 115)
Diameter 35mm/Total length 260 mm(include the cleaning cover)
The composite electrode is composed of internal reference
electrode, internal reference solution, electrode bulb, glass rod,
external reference electrode, external reference solution, liquid
interface, shell, electrode cap, electrode lead and socket.The
workmanship of each part of the ASP300 series electrode is very
- The reference electrode adopts Ag/AgCl, the potential is stable,
and the temperature coefficient is small.
- The reference solution is a KCl solid gel, which is not easy to be
lost, has a high concentration, a double connection structure, and
a long service life.
- The liquid junction is the connecting part that communicates the
external reference solution and the measured solution. This pH
electrode uses large-area annular porous PTFE, which has a fast
penetration rate, a fast response, and is not easy to be blocked.
- The glass support rod and the glass bulb adopt glass with the same
expansion coefficient. The glass bulb is hemispherical
low-impedance glass with high strength and not easily broken.
ASP300 series pH electrodes are widely used and can be used in
general industrial environments. It is most commonly used in the
pretreatment of water in reverse osmosis systems, recovery systems,
cooling towers, scrubbers, and factory sewage treatment systems.
However, for different environments, the chemical composition, flow
rate, temperature, pH range and pollutant level must be considered
to determine the most suitable pH electrode.
The installation of pH electrodes used in industrial environments
is very important. This plastic-cased pH electrode has mounting
threads on both ends, and the size is 1-inch NPT, which is easy to
install and suitable for different environments. Whether it is
installed in a pipeline, flow-through installation or submerged
installation is all possible.
