Fluoride ion standard solutions: For the calibration of fluoride measurements, HORIBA offers standard solutions with concentrations of 1 ppm and 10 ppm. TISAB solution: A special solution for use with fluoride ion standard solutions to adjust the ionic strength of the sample for precise fluoride measurements. ORP standard solution: For the calibration of redox measurements (ORP), HORIBA offers a solution with a redox potential of 225 mV. With these special solutions, the HORIBA LAQUAtwin pocket testers always provide accurate and reliable measurement results. The integrity of their measurement data and the lifetime of their devices can be ensured by regular calibration with these specifically formulated solutions. It is of great importance to select the appropriate calibration solution and standard solution to maintain the accuracy of measurements and ensure the reliability of water quality measurements in various applications. Important note regarding compatibility Please note: The replacement sensors, both old and new, are not compatible with one another. Similarly, the conditioning solutions for the old and new versions are not compatible with the respective device models. How can you tell if you have an older or a new device? If your Pocket Tester is marked ‘4-cell’, you have the latest version of this device. In this case, you will need the replacement sensors listed in the cross-selling section, as well as the standard and conditioning solutions.

Replacement sensor
The HORIBA LAQUAtwin Pocket Testers provide a comprehensive solution for immediate and precise measurement of water quality parameters directly in the field. To ensure that these measurements remain reliable and accurate, it is important to regularly check the sensors and replace them with spare sensors if necessary. The replacement sensors developed for the HORIBA LAQUAtwin series cover various types for different measurements: pH, conductivity, salinity, redox (ORP), as well as ion-selective sensors for sodium, potassium, nitrate, calcium, and fluoride. All of these sensors are designed to maximize user-friendliness and precision, qualities for which HORIBA is globally recognized in water quality testing. HORIBA replacement sensors ensure that users’ devices consistently deliver optimal performance and accurate measurements. Advantages of HORIBA Replacement Sensors Easy Replacement: Sensors can be quickly exchanged, allowing measurements to continue without delay. High Precision: Replacement sensors ensure that results are exact and reliable. Wide Measurement Range: Various sensor types are available to capture a broad spectrum of water quality parameters. Durability: Sensors are designed for long service life, even under challenging conditions. Sensor Replacement Instructions To ensure the longevity and accuracy of your HORIBA LAQUAtwin Pocket Tester, please follow these instructions when replacing a sensor: Removing the Sensor Turn off the tester. Carefully detach the sensor from the device and lift the sensor tip. Completely separate the sensor from the tester so that the two components are no longer connected. Installing the Sensor Ensure the tester is turned off. Check that the waterproof gasket is clean and undamaged. Attach the sensor to the tester by inserting hook “A” on the back of the device into hole “a” on the sensor tip. Make sure the waterproof gasket is not twisted. Important: After replacing the sensor, it is essential to follow the steps in the user manual of the respective tester to make the device ready for accurate measurements. (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, replacing the sensor is recommended. Regular checks and timely replacement of sensors are essential to ensure the high standards and reliability of water quality measurements performed with HORIBA LAQUAtwin Pocket Testers. Please note: The salt exchange sensors, both old and new, are not compatible with one another. Similarly, the conditioning solutions for the old and new versions are not compatible with the respective device variants. How can you tell whether you have an older or a newer device?
