JUMO tecLine HD pH/Rd
pH and redox combination electrodes, digital
with reusable JUMO digiLine electronics or
analog
Series 201021 — pH electrodes
Series 201026 — redox electrodes
Brief description
Premium matierals and components make JUMO tecLine HD electrodes particularly suitable for
the most demanding applications in process and industrial measurement technology. They are
designed as combination electrodes (glass or metal electrodes and reference electrodes in one
shaft). Depending on the model, a Pt1000 temperature probe can be optionally integrated.
An optimised PTFE ring diaphragm enables a quick response time while at the same time being
largely impervious to greater pollution loads or oily/fatty process water and wastewater. Alterna-
tively, a variant with a pinhole diaphragm is available as the optimal solution for processes with
a high solids content (e.g. wastewater with sand particles or media that is subject to precipitation
and/or crystallization reactions).
JUMO tecLine HD electrodes are state-of-the-art for modern pH and redox electrodes. Each top-
quality electrode is individually tested and supplied with a calibration certificate. Modern produc-
tion facilities ensure consistent characteristics.
All standard electrodes are manufactured using physiologically safe and FDA-listed materials.
They feature lead-free shaft glass and therefore comply with the RoHS-2 directive.
Type 201021/10...
Typical areas of application
Chemical industry:
Process water, high process pressures up to 13 bar, broad temperature range up to max. 135 °C,
and wide pH range from pH 0 to pH 14; suspensions, coatings and media with solid particles.
Industrial wastewater engineering:
Process wastewater, wastewater with highly contaminating media (presence of oil or electrode
poisons)
Galvanic:
Process water, media with electrode poisons (metal ions, complexing agents)
Power plants and waste incineration plants (flue gas scrubbing):
Wide pH range of pH 0 to pH 14, presence of fine ash particles
Sugar industry:
Consistent high temperature, presence of electrode poisons (e.g. sulfides)
The advantages of electrodes with combined JUMO dig-
iLine electronics
• Fail-safe digital data transfer for optimal process monitoring
• Modular system: for single measuring points and for establishing electrode networks
• Plug and Play function when connected to transmitters from the JUMO AQUIS touch series.
This facilitates the replacement of electrodes or the brief exchange of electrodes for calibra-
tion purposes.
• Also suitable for use with the JUMO mTRON T automation system
• Version with 4 to 20 mA output for integration into existing systems
• digiLine electronics can continue to be used even when the electrode becomes worn
• Easy and secure configuration in the lab using USB interface and JUMO DSM tool
(software)
Special features
• Low-maintenance thanks to dirt-repellant
PTFE ring diaphragm with polymerized
highly elastic gel
• Alternatively with a pinhole diaphragm for
suspensions, coatings and media with
solid particles
• Designed for use at a continually high
process temperature of up to max.
135 °C
1
• For process pressures of up to 13 bar
• Pt1000 temperature probe can be inte-
grated as an option
• With salt reserve to increase service life
in media with low conductivity
• Long service life with presence of elec-
trode poisons thanks to double-chamber
version
• Redox versions with platinum or gold tip
up to ±1500 mV
• Supplied with quality certificate
