JUMO ecoLine / JUMO BlackLine pH and redox combination electrodes versions with glass or plastic shaft (20.1005)
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 lowresistance 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 plastic version. This highly viscous KCI solution lends itself ideally to measurements in general acqueous 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, JUMO ecoLine electrodes feature a ceramic diaphragm. The model with plastic shaft in transparent PEI comes with a glassfiber diaphragm. A push-on proctection basket protects the sensor when used with handheld measuring equipment. The JUMO BlackLine has an open annular-gap diaphragm, the shaft is made from black PPO and features an integral protection basket....

Refine your measurement!
Highest accuracy and easy care - these are the two outstanding properties of Unitrode and Aquatrode Plus. The fixed ground-joint diaphragm is largely insensitive to contamination; its constant electrolyte flow guarantees a low-noise measuring signal even in difficult samples and independent of the measuring conditions.

SCHOTT® Instruments IoLine – pH electrodes for the most demanding measuring tasks
The new IoLine electrode family with iodine/iodide reference system from SCHOTT® Instruments has been developed to meet the most demanding laboratory measurement tasks. These electrodes are 100% metal ion free and hence ideally suited for measurements that are critical towards sample contamination by such ions (e.g. silver ions) and for pH measurements in Tris buffers too.
Advantages of IoLine Electrodes over classical Ag/AgCl reference systems are notably by:
• A longer service life thanks to a patented three-chambers Iod reservoir in the reference electrode.
• Fast reaction, precise measurement and clearly improved stability of measurement values, especially with changing temperatures or at temperatures other than the calibration temperature. This is due to the lower temperature sensitivity of the iodine/iodide reference potential.
• Free choice of the bridge electrolyte, hence optimum adaptation to the sample by double electrolyte system.
The electrodes are available in different membrane glass shapes and types and with different plugs to ensure that the user gets the instrument best suited to his needs. ID versions are available for use with SI Analytics’ s ProLab line of high-end laboratory meters.
IoLine electrodes are the right choice for the most critical pH measurements in research and quality control in pharmacy, biotechnology or food industry.

SteamLine electrodes are low-maintenance pH process electrodes for a wide temperature range from 0 to 135 °C and a pH application range from 0 to 14 pH.
The reference electrode uses a gel electrolyte. A special feature of these electrodes is the even, minimal flow of electrolyte: constant pressure is exerted on the electrolyte by a pressure mechanism that is integrated into the reference electrode. This ensures reliable and reproducible measurement results, and poisoning of the reference system can be avoided. That is why the useful life of SteamLine electrodes is substantially longer in comparison with non-pressurized, low maintenance electrodes.
We manufacture SteamLine electrodes out of the highly alkali-resistant S Glass developed for the most extreme conditions. As a result, the electrodes can not only be utilized for SIP applications (Sterilization In Place, temperature of up to 135 °C), but also for CIP cleaning applications (Clean In Place), in which hot, concentrated sodium hydroxide solution is utilized. Electrodes that were designed for this type of extreme cleaning processes can also demonstrate their strengths under other extreme application conditions.
SteamLine electrodes are available in different versions and lengths.

Orion ROSS Ultra® Premium pH Electrodes
The best of the best! The fastest response, highest accuracy, and best reproducibility that you can get with a pH electrode plus a 2 year warranty. ROSS Ultra pH electrodes combine all the benefits of the ROSS line with an extended life expectancy and minimized long-term drift. The ROSS reference offers stable, fast results regardless of temperature or sample composition.
Orion ROSS® pH Electrodes
The ROSS line offers precise pH measurements with unmatched stability, reliability, and rapid response regardless of temperature or sample composition. Since ROSS electrodes do not contain silver or mercury, they are well-suited for biological media, food, and pharmaceutical samples where metal ions cannot be tolerated. ROSS Sure-Flow® electrodes have a unique free flowing reference junction with an easy-to-clean design that assures stable, drift-free measurements.
Orion AquaPro Professional pH Electrodes
Low maintenance electrodes with an extended life, fast response, and clog-resistant junction. The double junction reference system prevents silver from coming in contact with the sample, so AquaPro electrodes can be used in samples where metal ions cannot be tolerated.
