TIENet®301 pH/Temperature Device
Section 1 Introduction
The TIENet Model 301 pH/temperature sensing device transmits
acidity/alkalinity data to the Signature® flow meter using
Teledyne ISCO’s TIENet connectivity.
The 301 device consists of a wall-mountable isolated interface
with a 10 or 23m cable, that attaches to the flow meter. Attached
to the device is a stainless steel, submersible probe with combi-
nation-type electrodes. The probe has a porous PTFE liquid
junction to resist fouling and coating, and a steam-sterilized
glass hemi-bulb for long- term stability.
The probe has a standard 25-foot cable, and built-in exposed tem-
perature sensor.

For greater distances, external connection via conduit, and con-
nection of additional TIENet devices, the TIENet Expansion Box
is available. Bulk TIENet cable may also be used for greater dis-
tances.
The maximum distance between the 301 and the flow meter is
1,000 ft. (304.8 m).
1.1 Operation The pH probe measures the acidity or alkalinity of an aqueous
solution by determining the relative quantity of dissociated
hydrogen ions, H+(actually H3O+) in the solution. A larger
quantity of H+ions indicates acidity, while a smaller quantity of
H+ions indicates alkalinity. The H in pH stands for Hydrogen
and the p stands for power.
The normal scale for pH runs from 0 to 14, with 0 being most
acidic and 14 being most alkaline. Distilled water at 25° C is
neutral at 7, based on the fact that the dissociation constant
(number of H+and OH -[hydroxyl] ions present) for pure water
at that temperature is 10-7.
The dissociation constant is a number indicating the degree of
ionic dissociation for a substance after it is dissolved in water.
Dissociation constants vary widely for substances, depending on
the nature of the substance’s chemical bonds. Ionic salts tend to
have higher constants.
Each number on the pH scale between 7 and 0 equals a tenfold
increase in H+ion. Each number between 7 and 14 equals a
tenfold decrease of H+ion. pH measurements of wastewater are
commonly made to monitor the effect of treatment chemicals
added to raise or lower the pH.
Water that has been used for various industrial processes may
deviate substantially from 7. Chemicals are often added to the
water to bring the pH close to that of neutral water, which is 7.
For example, if the effluent has a concentration of heavy metal
ions, they must be removed before discharge. Raising the pH of
solutions containing transition-metal ions will cause them to pre-
cipitate, where they can easily be removed as sludge. The
resultant solution will be high in pH and will require acid to neu-
tralize it.
1.2 Design The pH probe is a combination of two electrochemical half-cells.
Together they provide a low-voltage signal that corresponds to
the hydrogen-ion concentration of a solution. The bulb at the end
of the probe is called the glass mono electrode.
The glass is of special composition, sensitive only to hydrogen
ions, and is exposed to the solution to be measured. The specific
sensitivity to the hydrogen ion prevents interference from other
ions that may be present in the solution. It is essential to prevent
grease from fouling this membrane. The glass membrane pro-
duces an electrical potential proportional to hydrogen ion
activity.
The other electrode, called the reference electrode, completes the
circuit between the glass electrode and the solution.
