The membrane contains
HORIBA's unique combination
of rare earth metals to improve
response time by twofold and to
increase durability against

Technology
ToupH electrodes are now even stronger
HORIBA’s glass membrane molding technology achieves
strengths more than 10 times the Japanese Industrial
Standards (strength tests).
Covering the internal electrode with a cation-conductive hollow
fiber membrane, liquid junction clogging by silver ions and silver
complex ions is reduced to 1/1000 of the conventional technology.
Furthermore, maintained internal solution concentration ensures
a stable standard electrical potential.

Not just “unbreakable” .
New flat sensor innovations allow the
measurement of trace sample droplets or the
measurement of solid sample surface.
What is an ISFET (semiconductor sensor) ?
ISFET is the abbreviation of Ion Sensitive Field Effect
Transistor. The response membrane is equipped with
semiconductor based sensor.
1. Will not crack or break like conventional
glass electrodes
Special features
of the ISFET
The flat electrode has less than a 100μm distance
between the housing and the sensor
The unique structure
enables to measure
miniscule amount of
moisture on the surface of
solid objects and prevents
bubbles from trapping on the
sensor when measuring
samples in a beaker.
2. The sensor is flat and very small in size,
enabling the measurement of extremely
small samples
3. Easy handling and maintenance - simply
clean with a toothbrush
4. Can be stored dry
Precious,

Direct measurement
from micro tubes, only
50μL of sample

Effects of static
electricity is reduced
The combination of
HORIBA’s unique
semiconductor device
construction and improved
static protection circuit
means that the effects of
static electricity, once the
Achilles heel of
semiconductor sensors, are
greatly reduced.
