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 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.
