Das Redoxpotential wird mit einem pH-Meter mit Millivoltmeterfunktion in Verbindung mit einer Edelmetallelektrode (Platin oder Gold) und einer Referenzelektrode gemessen. Das Redoxpotential wird durch die Temperatur beeinflusst und muss bei einer konstanten Temperatur gemessen werden (z. B. bei 25 °C).
Mit anderen Worten, es ist das Energieniveau (elektrisches Potenzial), das durch die Gleichgewichtsbedingungen zwischen Oxidationsmitteln (Mz+) und Reduktionsmitteln (M (z-n) +), die in einer Lösung koexistieren, bestimmt wird.

The high-quality multi-parameter handheld meters of the HORIBA LAQUA 200 series are suitable for use under a wide range of conditions and in direct daylight in the field, thanks to their monochrome LCD display with LED backlight. Another advantage of these devices is that the handheld meters are particularly resistant to shocks and scratches due to their special rubber coating and offer a long operating time thanks to the AA batteries with 2500 mAh. An IP67 certification, which confirms dust-tightness and protection against temporary immersion for up to 30 minutes at a water depth of one metre, completes the professional overall package alongside the ergonomic design and easy operation. Confident in the quality of its products, HORIBA offers a three-year warranty on the handheld measuring devices of the LAQUA 200 series. During measurements, users are supported by instructions displayed in the form of smiley symbols. This helps prevent operating errors that could lead to implausible measurement results. Furthermore, the measuring device features only 9 buttons and no menu texts. This design helps ensure that the device remains easy to operate, even when used intermittently or by different users. Functions and Features HORIBA meters feature an electrode wear indicator, a hold function to "save" the current measured value on the display, automatic calibration functions and a self-diagnostic function. The fold-out stand on the back of the devices allows users to keep their hands free and carry out measurements easily and safely.

The HORIBA LAQUAtwin Pocket Tester series provides a comprehensive solution for immediate and precise measurement of water quality parameters directly in the field. To ensure these measurements remain reliable and accurate, it is essential to regularly check the sensors and, if necessary, replace them with spare sensors. The replacement sensors, specifically designed for the HORIBA LAQUAtwin series, cover a wide range of types for various measurements: pH, conductivity, salinity, redox (ORP), as well as ion-selective sensors for sodium, potassium, nitrate, calcium, and fluoride. Each sensor is engineered to maximize user-friendliness and accuracy, for which HORIBA is globally recognized in water quality testing. HORIBA replacement sensors ensure that users’ devices consistently deliver optimal performance and precise measurements. Advantages of HORIBA Replacement Sensors: Easy Replacement: Sensors can be quickly replaced, allowing measurements to continue without delay. High Accuracy: Replacement sensors ensure that results are exact and reliable. Comprehensive Measurement Range: Various sensor types are available to cover a wide range of water quality parameters. Durability: Sensors are designed for long service life under challenging conditions. Sensor Replacement Instructions: Follow these steps when replacing the sensor to maintain the longevity and accuracy of your HORIBA LAQUAtwin Pocket Tester: Removing the Sensor: Turn off the tester. Move the sensor slightly away from the device and lift the sensor tip. Detach the sensor completely from the tester. Installing the Sensor: Ensure the tester is turned off. Make sure the waterproof gasket is clean and intact. Mount the sensor onto the tester so that hook “A” on the back of the device fits into hole “a” on the sensor tip. Ensure the waterproof gasket is not twisted. Important: After replacing the sensor, follow the steps in the user manual of the respective tester to make the device ready for accurate measurement. (These manuals are available with the products. Calibration and, if necessary, conditioning are usually required.) How can I check if my sensor shows signs of wear? Check the sensor condition as follows: Perform a 2-point calibration. If an error occurs during calibration, this indicates that the sensor has deteriorated. In this case, it is advisable to replace the sensor. Regular checks and timely sensor replacement ensure that water quality measurements performed with the HORIBA LAQUAtwin Pocket Testers remain highly accurate and reliable.

The Milwaukee MA906BR/1 Reinforced pH/Redox/Temp replacement electrode for Milwaukee MW105 pH/Temp and MW106 pH/ORP/Temp meters.The MA906BR/1 has a rugged housing (epoxy) and comes with a 1m cable and BNC connector (meters sold separately).OPR probes for MW105 or MW106 are available separately.The probe connects quickly and firmly to a BNC connector. No slipping off is to be feared.
DESIGN FEATURESThe MA924B/1 offers the following design features:PLATINUM SENSING RINGThe platinum ring design is the preferred for most ORP applications.GLASS BODYGlass body is ideal use in wine applications as it is easily cleaned and gives fast results.DOUBLE JUNCTION REFERENCEThe double junction means that virtually no silver from the reference cell is mixed with the sample and reduces the risks of clogging.REFILLABLEThe ability to refill the electrolyte solution extends the life of the probe. Use MA9011 3.5M KCl fill solution. With a refillable ORP electrode, best results are achieved if the fill cap is removed to create a higher flow rate. This results in a faster and more stable reading.
