Connection cable for pH/redox Length: 3 metres Cable type: pH and redox connection cable Ø 5 mm, 75 °C Connection end 1 (sensor side): rotatable cable socket Connection end 2 (device side): without Electronic sensors for analysing liquids require special connection cables and plug connectors. The following applies in principle: The connection between an electrochemical sensor and the transmitter/indicator/controller should be as short as possible. Normally, the cable length is 5 to 10 metres to ensure a high level of functional reliability. If longer cable lengths are required in exceptional cases, the technical documentation for the sensors and measuring devices should be consulted. The cable between the sensor and the analyser must be laid directly, without interruptions such as terminal strips or cable extensions. pH and redox measurement Special coaxial cables with a special design are used for pH and redox measurement. During these measurements, the sensor generates low-intensity DC voltages which are transmitted to the analyser. Due to the sometimes very high internal resistance (potentiostatic measuring principle with internal resistances of up to several gigaohms), these measurements are extremely sensitive to electrical interference and the effects of radiation. Under unfavourable conditions, even minimal movements of the cable can lead to measurement value distortions. An additional insulation layer of the JUMO coaxial cable increases the insulation resistance, which enables a secure connection of the sensor to the transmitter. Conventional coaxial cables from the antenna and computer sector are not suitable for this application and can damage the sensors. This can lead to immediate failure of the sensor as well as a shortened service life. For multiple sensors, for example with integrated temperature sensors, coaxial cables with single wires are available, such as the Variopin (VP).

The HT glass is designed for a measuring range from pH 0 to pH 14 and is therefore suitable for applications where reliable measurements are required even at higher temperatures. This makes the electrode especially attractive for users looking for a durable solution for thermally demanding processes. Why should you choose this JUMO electrode? This version is particularly useful when several requirements must be fulfilled simultaneously: high temperature resistance, robust design for more difficult media, longer service life, and integrated temperature measurement. The hole diaphragm with gel made of polymerized solid electrolyte is particularly interesting for applications in which conventional diaphragms can become contaminated or clogged more quickly. The salt reserve additionally supports a longer service life. The integrated Pt100 is a clear advantage when the temperature needs to be measured directly at the measuring point, for example for temperature compensation or additional temperature monitoring within the process. The connection side is also designed for professional use. The VarioPin (VP) plug head Pg13.5 enables a suitable and clean connection to compatible measuring technology. With an installation length of 120 mm, the electrode is suitable for many common measuring points. Together with the sealed high-temperature gel and the cartridge reference system, this results in a well-designed version for processes where reliability, temperature resistance, and robust measurement technology are required.
