Horiba LAQUAtwin Fluoride Ion (F-) tester with 2 calibration points and temperature measurement (F-11)

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 essential to regularly check the sensors and replace them with spare sensors if necessary. The replacement sensors, developed specifically for the HORIBA LAQUAtwin series, cover a variety of types for different measurements: pH, conductivity, salinity, redox (ORP), as well as ion-selective sensors for sodium, potassium, nitrate, calcium, and fluoride. Each of these sensors is 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 replaced quickly, allowing measurements to continue without delay. High Precision: Replacement sensors ensure results are accurate and reliable. Comprehensive Measurement Range: Various sensor types are available to measure a wide range 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, follow these steps when replacing a sensor: Removing the Sensor: Turn off the tester. Slightly move the sensor away from the device and lift the sensor tip. Detach the sensor completely from the tester so there is no connection between the two parts. Installing the Sensor: Ensure the tester is turned off. Check that the waterproof gasket is clean and intact. Attach the sensor to the tester by inserting hook “A” on the back of the device into hole “a” on the sensor tip. Ensure that the waterproof gasket is not twisted. Important: After replacing the sensor, follow the instructions 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 recommended to replace the sensor. 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.
