Data Sheet 201005
V1.01/EN/00433884
JUMO ecoLine / JUMO BlackLine
pH and redox combination electrodes
in glass or plastic shaft versions
201005 series - pH electrodes
201010 series - redox electrodes
Brief description
The electrodes of the JUMO ecoLine and JUMO BlackLine series are high-quality measurement
sensors with a good price/performance ratio.
Active pH component: The JUMO ecoLine and JUMO BlackLine electrodes are equipped with
low-resistance JUMO UW glass. This guarantees fast and safe measurement results.
Active redox component: A sturdy platinum tip provides safe measurements and makes the
sensor easy to clean.
Reference system: Acrylamide-free JUMO gel is used in the glass and PEI plastic shaft versions.
This highly viscous KCl solution is ideal for measurement in general, aqueous media. The
electrolyte can be equipped with an optional "salt reserve" to increase the service life when
measurements take place in media with fewer ions or at high flow rates. A polymerized solid KCl
electrolyte is used in the JUMO BlackLine version. The JUMO cartridge-style conduction
system has proved its worth over the years and is the reference system used here. This keeps
the electrolyte free of silver ions throughout the life of the sensor, making it less susceptible to
electrode poisons.
In the "glass shaft" (1) version, JUMO ecoLine electrodes have a ceramic diaphragm. A glass
fiber diaphragm is provided for the plastic shaft version made from transparent PEI (2). A push-
on protection basket guards the sensor when it is used with hand-held meters. The JUMO
BlackLine (3) has a high-quality ceramic diaphragm. The shaft is made from black PPO and has
an integrated protection basket.
The option is available to have the electrodes delivered in a storage container (holder). This is
recommended if sensors are only used sporadically, to refresh them after lengthy periods of
intensive use, or if they are stored for extended periods of time.
OEM versions of all sensors can be supplied to order.
Special versions are available on request.

The foot of the KCl reservoir can
also be used as a mounting
wrench for pH and redox
electrodes with a Pg13.5 thread.
The indentations in the
(detachable) foot of the reservoir
fit the hexagon flats of the
electrode head.
When storing the electrodes, the
reservoir must be filled with KCl
(not with buffer solution
or similar).
The option is available to equip the
electrode with a salt reserve, in the
form of four salt rings (see
illustration).
This is recommended when using
the electrode in media with fewer
ions or at high flow rates.
The salt reserve helps to increase
the service life of the electrode.
The rings are not a manufacturing
defect (crystallization).
