Optical dissolved oxygen sensor with hard moulded 2m or 5m cable including a membrane cap. Manufacturer Part Nr. 3200780940 (2 metres = 300-D-2) 3200780942 (5 metres = 300-D-5)
The HORIBA Dissolved Oxygen Sensor Cap (300-D-M) is an essential component for performing precise and reliable dissolved oxygen measurements in aqueous environments. This replacement cap is designed for use with HORIBA DO sensors models 300-D-2 and 300-D-5. It is the ideal solution for ensuring the measurement accuracy and longevity of your oxygen meter. Advantages of the HORIBA Dissolved Oxygen Sensor Cap Extended Measurement Range: The sensor cap allows for comprehensive dissolved oxygen measurements, making it suitable for a wide variety of applications, from environmental monitoring to industrial processes. Adaptability to Environmental Conditions: With its operating temperature range, it can be used for measurements in diverse aqueous environments, from cool natural waters to warmer industrial process waters. Durable Material: Made from PVC and PMMA, the sensor cap offers high resistance to chemical exposure and mechanical stress, ensuring durability in challenging measurement conditions. Easy Installation: The sensor cap can be replaced quickly and easily, reducing maintenance time and improving operational efficiency. Quick Guide to Replacing the Sensor Cap Remove the old cap: Detach the existing sensor cap from the DO sensor to make room for the new one. Attach the new cap: Secure the new sensor cap to the DO sensor so it can be quickly put back into service. Set the parameters: Enter the specific membrane parameters of the new cap into the meter to optimize measurement accuracy. Calibration process: Use the dedicated calibration function (“CAL in cap replacement”) to fine-tune the measurements with the new cap. Note: The detailed procedure for setting the membrane parameters and performing calibration is described in the device’s user manual. Following these steps ensures your meter is promptly and efficiently configured for the new sensor cap, maintaining accurate measurements over time. For anyone who depends on precise dissolved oxygen measurements, the HORIBA Dissolved Oxygen Sensor Cap (300-D-M) is indispensable. With its robust design, extended measurement range, and ease of use, it greatly enhances the reliability and service life of your HORIBA oxygen meter.

The JUMO digiLine O-DO S10 is a modern, intelligent sensor for measuring dissolved oxygen. The measurement is based on the optical principle of luminescence quenching according to ASTM D888-05. This offers users numerous advantages: No electrolyte replacement required No polarization voltage necessary No minimum flow required Longer calibration intervals thanks to low drift behavior Long-term stable and reliable measurement results Temperature compensation is performed automatically, so that the measured value is always output temperature-compensated. In addition, the sensor can also correct the measured value with regard to air pressure and salinity (using external sensors). The JUMO digiLine O-DO S10 has two interfaces for transferring the measured values to higher-level systems or automation solutions: digitally via an RS485 interface with Modbus RTU protocol or analogically via a 4...20 mA two-wire signal. Configuration, parameterization, and calibration data are stored in the sensor's electronics. Sensor-specific information and measuring point identifiers can also be stored there and read out as needed. In addition, the sensor offers a logbook that documents the last ten successful calibrations, providing an overview of the calibration history. To support operational safety, the sensor is equipped with a self-diagnostic function that issues warnings or error messages in the event of malfunctions. The sensor features a slim, robust design. The sensor cap can be easily replaced when worn. The sensor body is made of durable PVC and is therefore suitable for applications in fresh and salt water. A permanently attached cable with a 5-pin M12 connector ensures quick and easy connection to measuring or automation devices. The sensor offers two connection options for installation: an Rp 1 thread directly on the sensor shaft or, alternatively, an optionally available mounting kit with a G 1 thread. Frequently Asked Questions What can I use the oxygen sensor for? To display and measure dissolved oxygen in water or liquids. How accurately does the device measure oxygen? It uses state-of-the-art optical technology to provide stable, long-term reliable readings. The measurement is based on the optical principle of luminescence quenching in accordance with ASTM D888-05. Can I transmit the readings to my control system? Yes, via a digital RS485 interface or as an analogue 4–20 mA signal. Does the sensor display the readings itself? No. The sensor provides the readings, which are displayed, for example, on a meter or PC. Is the sensor robust and suitable for use in water? Yes, it has a robust PVC housing and is suitable for fresh and salt water. Why is dissolved oxygen important in the first place? It indicates water quality, e.g. in fish farming, sewage treatment plants or industrial processes.
