pH and Redox Combination Electrodes
JUMO ecoLine / JUMO BlackLine
versions with glass or plastic shaft
201005 Series - pH electrodes
201010 Series - redox electrodes
Brief description
Electrodes in the JUMO ecoLine und JUMO BlackLine series are high-quality measuring
sensors with an optimum price/performance ratio.
Active pH element:
JUMO ecoLine electrodes have been manufactured using the JUMO U glass
that has proved itself for many years. JUMO BlackLine electrodes are equipped with the low-
resistance JUMO UW glass. This guarantees fast and safe measurement results.
Active redox element: A robust platinum tip ensures reliable measurements and allows simple
cleaning of the sensor.
Reference system: The acrylamide-free JUMO gel is used for the glass version and the PEI plas-
tic version. This highly viscous KCI solution lends itself ideally to measurements in general ac-
queous media. For measurements in media containing few ions, or with high flow rates, the
electrolyte can be equipped with an optional “salt reservoir” for a longer operational life. The
JUMO BlackLine model employs a polymerized KCl solid electrolyte. The JUMO cartridge-type
conduction system – tried and tested for many years – is used as the reference system. So the
electrolyte remains free from silver ions and therefore less susceptible to electrode poisons.
In the glass shaft version (1), JUMO ecoLine electrodes feature a ceramic diaphragm. The
model with plastic shaft in transparent PEI (2) comes with a glassfiber diaphragm. A push-on
proctection basket protects the sensor when used with handheld measuring equipment. The
JUMO BlackLine (3) has an open annular-gap diaphragm, the shaft is made from black PPO and
features an integral protection basket.
The electrodes can optionally be supplied in a storage receptacle, which is recommended if the
sensors are only used sporadically, for refreshing them after lengthy and intensive use, or if
stored for an extended period.
All sensors can be supplied as OEM versions to special order.
Special versions are available on request.
