You use this electrode to measure the pH value of liquids. This means you can determine whether a liquid is acidic, neutral, or alkaline. Is the electrode suitable for heavily contaminated water? Yes, it is specifically designed for dirty and challenging media such as wastewater or paints. This robust industrial electrode is engineered for the most demanding applications involving high levels of contamination and toxins, as well as oily media. Can I use it to measure high temperatures? Yes, it is suitable for applications up to 130°C and remains stable under these conditions. Does this electrode require a lot of maintenance? No, it features a robust design and requires minimal regular maintenance. Is the measurement reliable in the presence of oil or dirt? Yes, it delivers stable readings even in oily and heavily contaminated media. How long does the electrode last in industrial use? Its heavy-duty construction ensures a significantly extended service life.

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). JUMO order code: A JUMO order code uniquely identifies a specific measuring instrument or component based on its configuration. You will find the exact JUMO order code for your instrument configuration in the relevant data sheet from page 2 onwards. This can be found under ‘Downloads’ for the product. Frequently Asked Questions Is this cable compatible with my pH or redox electrode? Yes, if your electrode has a rotatable cable connector (on the sensor side), you can use this connection cable without any issues. What is the unterminated cable end (without a plug) intended for? The open end is ideal if you wish to connect the cable directly to a measuring device or an existing terminal block. Why does the cable have a rotatable connector at the sensor end? The rotatable connector makes installation easier and prevents the cable from twisting during mounting. Can I extend or shorten the cable? The open end can be modified, shortened, or connected to a suitable plug as needed. Is the cable suitable for use in water or damp environments? Yes, it is designed for typical measurement environments associated with pH and redox monitoring. How do I correctly connect the cable to my electrode? Simply attach the rotatable connector to the electrode's connection point and tighten it securely. Is the cable suitable for continuous use? Yes, it is designed for the regular and continuous operation of pH or redox measurement systems. What should I do if I am unsure whether the cable fits? Simply send us the details of your electrode or measuring device—we will be happy to assist you.

The Horiba 9600-10D PUREIL pH electrode can perform pH measurements in water within five minutes without affecting its conductivity thanks to its gel ion liquid salt bridge. This pH electrode allows pH values in water with low conductivity to be measured accurately and quickly. An innovative pH electrode that does not release KCl Accurate readings through quick and easy measurement This pH electrode is used to determine pH values in water in order to reliably determine pH values. It supports measurements in the pH range 0-14 and is ideal for water with low conductivity (<100 µS/cm) such as ultrapure water samples (e.g., distilled water, rainwater, reverse osmosis water, and boiler water). KCl is usually diffused in pH electrodes, but the use of a newly developed ionic liquid salt bridge now makes it possible to stabilize the potential difference at the liquid interface. When measuring with the 9600-10D PUREIL pH electrode, no potassium chloride is released that could influence the measurement or the pH value in samples with low ionic strength or special solutions. Advantages: Maintenance-free and waterproof Built-in temperature sensor for automatic temperature compensation Minimal dissolution of the ionic liquid during the measurement process Precise and fast measurement even with samples with low electrical conductivity The impact on the sample is a maximum of 1/10,000 compared to conventional methods Measurements are also possible with samples that react with KCl Waterproof construction Suitable for: Can be used for water with low electrical conductivity (pure water, rainwater, river water) and medical solutions (injections). Solutions that react with KCl (potassium chloride) or contain ions, such as injection solutions. Not suitable for: Since the Pure IL pH electrode uses an ionic liquid as a salt bridge as a reference electrode, it is not suitable for measuring samples containing surfactants, heavy metal ions, or organic solvents. For acidic samples, citrate buffer (pH 3.776 at 25 °C) is recommended for calibration instead of phthalate buffer (pH 4.01 at 25 °C) in order to achieve a more accurate measurement. Why should I use this electrode? The 9600-10D PUREIL is a very good and stable pH electrode. If you value speed and accuracy, this electrode is the right choice.
