HORIBA Nitrate (NO₃⁻) Replacement Electrodes – Long-Term Reliable Measurement Values for Clear Environmental Analyses
When trends can no longer be clearly identified – buy your Horiba replacement electrode online now
Nitrate values are often used to assess changes in water bodies or processes. When measurement series suddenly appear illogical or trends can no longer be clearly displayed, the cause is often not the system itself – but the electrode.
Reliable basis for well-founded evaluations
The determination of nitrate serves as an important indicator of nutrient inputs and environmental pollution. To ensure reliable evaluation, the electrode must provide stable and reproducible results.
With suitable HORIBA replacement electrodes, existing measurement systems can quickly be restored to a precise performance level.
Typical signs that replacement is needed
-
Unclear or contradictory measurement series
Trends can no longer be interpreted clearly, making the evaluation of developments more difficult. -
Low comparability of samples
Similar samples deliver different results even though conditions are identical. -
Declining measurement stability
Measurement values fluctuate more than usual and lose reliability.
Typical application areas
- Monitoring nitrate in water bodies and groundwater
- Use in environmental analysis and water treatment
- Control of nutrient inputs
- Laboratory and on-site measurements
Your advantages
- Reliable and reproducible measurement results
- Restoration of clearly interpretable measurement data
- Easy integration into existing systems
Ensure reliable nitrate values and gain clear insights into changes in your measurement data.
HORIBA Nitrate Replacement Sensor (S040) for Pocket Testers NO3-11, NO3-11C and NO3-11SThe HORIBA LAQUAtwin Pocket Tester series allows water quality parameters to be measured quickly and accurately on site. To ensure that these measurements are reliable and accurate, it is very important to check the sensors regularly and replace them with replacement sensors if necessary. These replacement sensors have been specially developed for the HORIBA LAQUAtwin series and offer a wide range of variants for different measurements: pH value, conductivity, salinity, redox (ORP) and ion-selective sensors for sodium, potassium, nitrate, calcium and fluoride. Each of these sensors has been designed with the aim of maximising user-friendliness and accuracy, for which HORIBA is known worldwide in the field of water quality testing. The advantages of HORIBA replacement sensors are: Easy replacement: It is easy to replace the sensors, allowing measurements to be resumed quickly. Highest accuracy: The replacement sensors ensure that the measurement results are precise and reliable.Wide range of measurements: Different 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 replacing the sensor: To ensure that your HORIBA LAQUAtwin Pocket Tester is durable and accurate, please follow these steps when replacing the sensor:Remove the sensor Switch off the measuring device. Lift the tip of the sensor. Then slide the sensor slightly away from the measuring device. Remove the sensor completely from the measuring device (by pulling).Attaching the sensor Switch off the measuring device. Make sure that the water-repellent seal is clean and undamaged. Press the sensor onto the measuring device so that hook ‘A’ on the back of the device fits into hole ‘a’ on the tongue of the sensor.Make sure that the waterproof seal is not twisted. Important:To put the measuring device back into operation for correct measurement, follow the steps in the operating instructions for the corresponding tester after replacement. (Our products include such instructions. 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: Perform a 2-point calibration to check the sensor condition. If a calibration error occurs, this suggests that the sensor is deteriorating. The sensor should therefore be replaced. Regular checks and timely replacement of sensors ensure the high quality and reliability of your water quality measurements using the HORIBA LAQUAtwin Pocket Testers.
