Important note on compatibility Please note: The Horiba LAQUAtwin conductivity, TDS and temperature multi-parameter testers, 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? 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. These have been specially optimised for the new pocket testers and are not suitable for the older models. Manufacturer Part No.: 3999960110

Note: Conditioning solution 514-4EC-CON is only suitable for the LAQUAtwin 4EC-11, 4EC-22, 4EC-33 and 4ECSalt-11 testers. Manufacturer’s item number: 3201081522

To accurately calibrate and maintain the HORIBA LAQUAtwin Pocket Testers, HORIBA provides a special selection of buffer, calibration and standard solutions. A convenient pack size of 6 x 14 ml of these solutions meets the requirements of the pocket testers as only a few drops are needed for calibration. This specific pack size helps to reduce waste and optimize efficiency during regular calibrations. The solutions available cover a variety of measurement ranges, allowing users to select the appropriate solution to suit their individual analysis or measurement needs: pH buffer solutions: Solutions with pH values of 4.01 or 7.00 are available to calibrate the pH measurement. With these buffers it is possible to precisely regulate and control the pH measurement function of the LAQUAtwin Pocket Tester. Conductivity standard solutions: 1413 μS/cm standard solutions ensure that the conductivity measurement of your devices is carried out precisely. NaCl standard solutions: 0.5% or 5.0% NaCl solutions are available for the calibration of salinity measurement. Ion standard solutions: HORIBA provides standard solutions to calibrate ion selective measurements. HORIBA provides standard solutions for sodium, potassium, nitrate and calcium, available in different concentrations: from low (e.g. 150 ppm) to high concentrations (e.g. 5000 ppm). 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. These have been specially optimised for the new Pocket Testers and are not suitable for the older models. Manufacturer Part No.: 3999960114
