JUMO tecLine CL2 sensor for free chlorine

Flow monitors for disinfection variables Membrane-covered sensors for water disinfection (e.g. free chlorine or total chlorine, ozone, chlorine dioxide, etc.) must be operated with a minimum flow rate of 15 cm/s. The flow monitor is integrated into the sample water supply line, in series with the disinfection sensor, and monitors the required minimum flow to the sensor. Below the minimum flow velocity, the sensors measure values that are too low. This can cause a connected control system to dangerously overdose or underdose. Above the minimum incident flow velocity, the measuring signal is only slightly influenced by the incident flow velocity. The flow monitor consists of a flow body, a needle valve insert for flow regulation and an inductive proximity switch, which is controlled by a float in the medium flow. When the minimum flow velocity is reached or exceeded, the float rises and the contact of the inductive proximity switch switches. The contact can be used, for example, to control a binary input of the controller for standard signals, JUMO AQUIS 500 AS. If the flow is too low, the controller is set to the ‘HOLD’ state. This prevents incorrect dosing.   Areas of application Flow monitoring when using sensors for free chlorine, chlorine dioxide, ozone, hydrogen peroxide or peracetic acid

The electrode measures in the pH range from 0 to 12, and for short periods up to pH 14. It is equipped with the low-ohmic JUMO UW glass, which supports fast and stable measurement results. JUMO ecoLine glass shaft pH electrode with KCL container, S8 Pg13.5 screw head – type key: 201005/51-18-22-0000-00-120/052, part no.: 00402273 This version of the JUMO ecoLine pH electrode is designed for reliable pH measurements in general aqueous media and offers a convincing price-performance ratio. Thanks to the additional KCL container, it is particularly practical when the sensor is not in continuous use, needs occasional refreshing, or is stored for longer periods. The ceramic diaphragm and polymerized KCl solid electrolyte make this sensor a suitable solution for many standard applications in water analysis. The proven JUMO reference system also helps ensure that the electrolyte remains silver-ion-free over its service life and is less susceptible to certain electrode poisons. Typical applications With S8 Pg13.5 screw head and 120 mm immersion length, this ecoLine pH electrode is suitable for many common installation situations. An integrated temperature sensor is not available in this series. The included KCL container is a useful advantage when the electrode is only used occasionally or needs to be stored safely between uses. drinking water monitoring water treatment swimming pools, aquaristics slightly polluted service, process and wastewater rainwater, pond and surface water applications horticulture applications food and beverage industry Not recommended for electroplating water treatment industrial process and wastewater ultrapure water therapy baths biotechnology and sterile processes

This electrode is particularly suitable wherever a cost-efficient, proven, and long-life-oriented electrode is required for general aqueous media. JUMO ecoLine glass shaft pH electrode with salt reservoir, S8 Pg13.5 screw head (type key: 201005/51-18-22-0000-00-120/837, part no.: 00447837) This JUMO ecoLine glass shaft pH electrode is a reliable choice for pH measurements in general aqueous media. It is designed for users who are looking for an economical, practical, and robust electrode suitable for many standard water applications. The version with salt reservoir is particularly advantageous when the electrode is used under conditions where extended service life is beneficial. Technical data Design: glass shaft pH electrode Measuring range: pH 0 to 12, short-term up to pH 14 Temperature sensor: none Active element: JUMO UW glass Diaphragm: ceramic Electrolyte: polymerized KCl solid electrolyte Reference system: JUMO cartridge reference system Electrical connection: S8 Pg13.5 screw head Immersion length: 120 mm (standard) Type extension: salt reservoir Advantages and special features The electrode measures in the pH range from 0 to 12, and for short periods up to pH 14. It is equipped with low-ohmic JUMO UW glass, enabling fast and stable measurement results. The ceramic diaphragm and polymerized KCl solid electrolyte make it suitable for many standard applications in water analysis. The proven JUMO cartridge reference system ensures that the electrolyte remains free of silver ions over its service life and is less susceptible to certain electrode poisons. Why choose this electrode? This version is particularly suitable when a pH electrode for general water applications is required that offers more than a basic standard model. The salt reservoir is especially beneficial in low-ion media or higher flow conditions, as it can extend the electrode’s service life. For this reason, it is ideal for users seeking a more durable solution for regular operation rather than a basic version without additional type extensions. With the S8 Pg13.5 screw head and 120 mm immersion length, the electrode fits many common installation situations. An integrated temperature sensor is not available in this series, keeping the focus entirely on reliable pH measurement.

The JUMO AQUIS RS is a practical solution when measurement values from digital sensors should not only be displayed but also directly processed and controlled. It is ideally suited for industrial applications in which measurement values are not only recorded but also evaluated and controlled. Digital sensors can be directly integrated via the integrated RS485 interface (Modbus). In addition, an analog temperature input is available, allowing external temperature sensors such as Pt100 or Pt1000 to be connected. The power supply for connected sensors is provided directly by the device, reducing installation effort. The LCD graphic display ensures a clear presentation of the measured values. Depending on requirements, these can be displayed as numeric values, bar graphs, or trends. The menu navigation is clearly structured and enables easy operation during ongoing use. In addition to the pure display function, the AQUIS RS also performs control tasks. With optional relay outputs, switching and alarm functions as well as more complex control functions with P, PI, PD, or PID behavior can be implemented. This makes the device suitable for both simple monitoring tasks and more demanding process control applications.
