Product information "Horiba LAQUAtwin S070 Cond Replacement Sensor for EC-11, EC-22, EC-33 tester "
The HORIBA LAQUAtwin Pocket Tester series allows water quality parameters to be measured quickly and accurately directly on site. To ensure that these measurements are reliable and accurate, it is essential to check the sensors regularly and replace them with replacement sensors where necessary.
These replacement sensors have been specifically developed for the HORIBA LAQUAtwin series and offer a wide range of variants for various measurements: pH, conductivity, salinity, redox (ORP), as well as ion-selective sensors for sodium, potassium, nitrate, calcium and fluoride. Each of these sensors has been developed with the aim of maximising the user-friendliness and accuracy for which HORIBA is renowned worldwide in the field of water quality testing.
The advantages of HORIBA replacement sensors are:
- Easy replacement: The sensors are easy to replace, allowing measurements to resume quickly.
- Highest accuracy: The replacement sensors ensure that measurement results are precise and reliable.
- Wide range of measurements: Various types of sensors are available for different water quality parameters.
- Durability: The sensors are designed to have a long service life, even under challenging conditions.
Instructions for sensor replacement:
To ensure that your HORIBA LAQUAtwin Pocket Tester remains durable and accurate, please follow these steps when replacing the sensor:
Fitting the sensor
- Switch off the meter.
- Ensure that the water-resistant seal is clean and undamaged.
- Press the sensor onto the meter so that the hook ‘A’ on the back of the meter fits into the hole ‘a’ on the sensor tab.
- Make sure that the waterproof seal is not twisted.
Important:
To get the measuring device back up and running for accurate measurements, follow the steps in the user manual for the relevant tester after replacing the sensor. (Our products include such manuals. In most cases, calibration and, if necessary, conditioning are required.)
Question: How can I check if my sensor is worn out?
Answer: By checking the condition of the sensor as follows:
To check the sensor condition, perform a 2-point calibration. If a calibration error occurs, this suggests that the sensor is deteriorating. The sensor should therefore be replaced.
By carrying out regular checks and replacing sensors in good time, you can ensure the high quality and reliability of your water quality measurements using the HORIBA LAQUAtwin Pocket Testers.
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.
