BlackLine pH/ORP electrodes with plastic shaft and fixed protection basket.Selected version: Without temperature sensor (not available for this series, only for Jumo tecLine and tecLine HD series)Screw head S8 Pg13.5 with fixed two meter cable and BNC connectorGlass fibre diaphragm Plastic shaft PEI Fitting length 120mm (standard) Type code (can also be found on your electrode): Type 201010/65-22-65-2000-76-120/837 ; part-no. 00424950 The electrodes of the JUMO BlackLine series are high-quality measuring sensors with a favorable price/performance ratio.Active part pH The JUMO BlackLine plastic electrodes with fixed protection basket are equipped with the low-resistance JUMO UW glass. 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.

2-electrode principleproven versions for industrial use measuring ranges 0 ... 1 mS/cm (K = 0.1) or 0.01 ... 15 mS/cm (K = 1.0) temperature range up to 55 °C, maximum pressure up to 6 bar at 25 °C JUMO ecoLine CR-PVC conductive 2-electrode conductivity sensorBrief description: Conductivity sensors of the 202923 series are used, for example, in general water technology, cooling and air-conditioning systems, drinking and bathing water, or in industrial rinsing and process water circuits. The body material PVC limits the application to medium temperatures up to 55 °C. Two versions with cell constants K = 0.1 or 1.0 are available. Versions with the common thread sizes G 3/4" or G 1" or a plug-in version are available for installation. The plug-in version is used, for example, with the matching PVC tees in nominal sizes DN 25, 32 and 40 and allows the sensor to be quickly dismantled for cleaning or maintenance. The electrical connection is made either via a detachable device plug or via a fixed cable connection. The overall construction and the parts in contact with the medium are physiologically harmless. The electrode material is stainless steel (K = 0.1) or special graphite (K = 1.0). The optionally integrable temperature sensor allows simultaneous recording of the medium temperature for temperature compensation in downstream measuring amplifiers.Stainless steel variant K = 0.1 The sensor has 3 metallic pin electrodes. The two outer pins are electrically connected and form one pole of the 2-electrode conductivity sensor. The counter electrode is the middle stainless steel pin. This design achieves very high measurement precision with low stray fields. A temperature sensor can be integrated in the middle pin. Graphite variant K = 1.0 For physical reasons, special graphite is used as the electrode material for higher conductance values. The two graphite electrodes are completely integrated in the electrode shaft. The optional temperature sensor is located in a stainless steel sleeve that is immersed in the measured medium. Operating principleThe sensors of the 202923 series are 2-electrode conductivity sensors. An AC voltage is applied to them by the transmitter. The current flowing across the liquid and the electrodes is determined by the conductivity of the liquid
