Measurement of the pH value plays an
important role in many areas. Anywhere where
there are chemical and biochemical reactions,
the pH value has an important indicator
function.
Although the technology to accurately measure
pH value has been available for several years,
instruments previously available have posed
several problems for users:
· Short life span of pH probes due to glass
· Sensitivity to dirt of the pH probe resulting in
· Spillage of storage solution
· Handling problems when calibrating
· Lack of one-hand penetration pH probes for
· Lack of combined temperature and pH
Together with experts from trade and
industry, Testo has developed innovative
instruments that resolve these problems.
Instead of a liquid electrolyte, Testo pH probes
have a gel electrolyte as a reference substance
for pH measurement which facilitates the use of
a hole diaphragm between the measurement
electrode and housing in place of the micro-
porous structure usually used in pH probes.
The micro-porous structure becomes blocked
up more quickly, similar to a finely woven sieve,
consequently requiring regular service which in
return results in a shorter life.
Due to the large volume of gel electrolyte and
the hole diaphragm, Testo pH probes are not
only leakproof, they are almost completely
maintenance-free, robust and unaffected by
dirt and dust.
The combination of the pH penetration tip and
temperature probe in a one-hand instrument for
accurate and fast temperature compensation is
unique. Consequently, accurate readings are
guaranteed in all ambient conditions.

With the development of different, breakproof
probe geometries, Testo is making available
special solutions for liquid as well as for
semi-solid substances.
The leakproof storage solution is also new.
pH probes must be stored in moist conditions
when not in use, in order to prevent the glass
membrane coating around the measurement
electrode and the diaphragm from drying out.
Pure water alone should not be used since
water would release the conducting
components contained in the probe
electrolytes. A potassium chloride solution is
usually used for this purpose. As with every
liquid, it can leak which, particularly in the food
branch, can lead to contamination of raw
foodstuffs or products.
Testo has produced a solution that has
eliminated this disadvantage. The potassium
chloride solution is available in a gel filled
cartridge that does not drip or leak.
