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).

This guarantees fast and reliable measurement results. Active part redox The robust platinum tip ensures reliable measurements and is also easy to clean. Reference system The Black Line plastic shaft version PEI uses a polymerised KCl solid electrolyte. This is ideally suited for measurements in aqueous media. For measurements in media with fewer ions or at high flow rates, the electrolyte can be equipped with an optional "salt reservoir" to increase the service life. A polymerized KCl solid electrolyte is also used with this electrode, and the JUMO cartridge discharge system, which has been tried and tested for years, is used as the reference system. Here, the electrolyte remains free of silver ions over the lifetime of the sensor and is therefore less susceptible to electrode poisons. The JUMO BlackLine has a high-quality ceramic diaphragm. The shaft is made of black PPO and has a permanently integrated protective basket. Optionally, the electrodes can be supplied in a storage container (quiver). This is recommended if the sensor is only used sporadically, for refreshing the sensor after longer, intensive use or for longer storage periods. All sensors can be supplied as OEM versions on request. Special versions on request.

Brief description The high-quality materials and components of the JUMO tecLine HD electrodes make them particularly suitable for the most demanding applications in process and industrial measurement technology. They are combined combination electrodes (with a reference electrode and a glass or metal electrode in a shaft).Depending on the design, it is possible to integrate an additional Pt1000 temperature sensor.Insensitive to large amounts of dirt as well as processes and waste water rich in oil and grease. For processes with a high solids content (e.g. waste water with sand particles or media that are subject to precipitation or crystallisation reactions), a perforated diaphragm variant is available as the optimum solution. JUMO tecLine HD electrodes represent the latest technology for pH and redox electrodes. Each electrode is a high-quality product that is individually unit-tested and comes with a calibration certificate. Modern production facilities guarantee constant values.All conventional electrodes are made from physiologically safe and FDA-listed materials.Their shaft glass is lead-free and therefore RoHS 2 compliant.
