SENZORI PENTRU MARIMI ELECTROCHIMICE SI TEMPERATURA

Gas-sensitive sensor for measuring ammonia (20.1030)
This sensor can be used to measure ammonia (NH3) in aqueous solutions. The ammonia sensor consists of a pH glass electrode and a reference electrode. Both electrodes are in an electrolyte.
The electrolyte is separated from the sample medium by means of a hydrophobic, gas-permeable membrane. The pH of the electrolyte changes if NH3 gas diffuses through the membrane. This local change in pH is measured by the pH electrode as a high-resistance value.


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 (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.

pH and Redox Combination Electrodes for laboratory measurements with glass or plastic shaft (20.1030)
These electrodes are high-quality sensors for pH and redox potential (ORP) measurements in the laboratory.
The sensors can be supplied with either a glass shaft or a sturdy plastic shaft.
These electrodes are suitable for all measurements in liquid media. They offer a high degree of measurement accuracy and reliability for all applications. A special electrode is available for the ion-selective measurement of ammonia, see page 11.
Suitable models are available for the most diverse requirements:
Active component for pH: There is a choice of different membrane glasses for the pH versions.
Active component for redox: A sturdy platinum or gold tip can be supplied.
Reference system: The tried and tested JUMO silver/silver chloride conductive system (Ag/AgCl) and the acrylamide-free KCl gel together constitute the reference system.
The conductive system is designed in cartridge style. As a result, the reference electrolyte remains free from sliver ions over the entire life span of the sensor, which makes it less susceptible to electrode poisons.
Diaphragm: In the standard version, JUMO labLine electrodes feature a sturdy ceramic diaphragm in zirconium dioxide. On the models with a plastic shaft, a glass fiber diaphragm forms the connection between the substance being measured and the reference system. PTFE and ground diaphragms are available for special applications.
Electrical connection: The electrical connection of the sensors is made through:
- S6 plug cap
- plug cap with attached cable


tecLine Rd pH and redox combination electrodes with glass or plastic shaft (20.1020)
JUMO tecLine electrodes are high-quality sensors for professional application in process and industrial measurement technology. The use of materials and components that meet the highest standards is the distinguishing feature of these electrodes.
They are designed as combined electrodes (the glass or metal electrode and the reference electrode are combined in a single shaft). Depending on the type, a temperature probe can additionally be integrated (option).

pH glass electrodes, Redox metal electrodes, Reference electrodes, Diaphragm tubes, Compensation thermometers, Glass conductivity cells (20.1080)
pH glass electrodes:
pH glass electrodes are used in conjunction with reference electrodes for measuring the pH value.
Reference electrodes:
Reference electrodes have the task of providing a constant potential for potentiometric measurements. The potential of an indicator electrode (e.g. a pH glass electrode) serves as the counterpoint.
Redox metal electrodes:
Metal electrodes consist of a glass or plastic shaft that has a metal pin or metal tip fused or glued into the lower end. Metal electrodes are used to determine the redox potential of aqueous media, in conjunction with reference electrodes.
Diaphragm tubes:
Due to physical and/or chemical interactions between sample medium and reference system, potentiometric measurements can be disturbed or falsified by electrochemical sensors. In such cases, it is advisable to use an electrolyte bridge, which is set up with the help of a diaphragm tube.
Compensation thermometers:
Temperature errors may falsify the measurement signal during electrochemical measurements. Measurement errors due to temperature can be compensated by using compensation thermometers.
Glass conductivity cells:
Glass conductivity cells are used to determine the electrolytic conductivity of aqueous solutions. The cells have the cell constant K = 1.0 1/cm
