It is characterised by its user-friendly handling and environmentally friendly design and can be used for a wide range of applications.Features:Measurement parameters: Nitrate (NO3-) Solid-state electrodes that do not require refillingDouble junction made of porous sintered polyethyleneIntegrated temperature sensor Environmentally friendly design made from bio-based plasticSupplied with calibration and ionic strength adjustment solutionsRobust housing made of polycarbonate and PVCLow maintenance, simply rinse and sealWaterproof according to IP67Linearity in measurement range:The range where the calibration curve has linearity is called the measurement range. When lower concentration is measured where the linearity is not established, perform calibration at two points in the lower concentration range.Influence of pH:The impact of the pH may cause a decrease in the slope of the ion selective electrode, or parallel shifting of the calibration curve. To prevent these effects, set the pH to an appropriate value in advance and keep it constant.Interfering ions:Ion selective electrodes have good selectivity with respect to the ions to be measured, but they may react to the other ions. When using the ion electrode method, it is important to know the effects of coexistent ions and take measures to avoid them. Interfering ions may form compounds with poor solubility or may form complex salts with the structure material of the ion selective membrane, these may to have a significant impact on the measured value.Conditioning:An electrode is conditioned by soaking it in a standard solution for 1 hour or longer. Use a standard solution whose concentration is 100 mg/L or more.In the following cases, perform conditioning of the electrode before calibration.• Before the first use.• Before use after storage for 2 weeks or longer.• If the electrode is less responsive.Calibration:Always calibrate with at least 2 calibration solutions which are 1 decade apart and bracket the expected measurement value.Use fresh calibration solutions and do not re-use them.• Below 10 ppm (mg/L)First solution between 1 and 10ppmSecond solution between 10 and 50 ppm• Between 10 and 100 ppm (mg/L)First solution between 10 and 100ppmSecond solution between 100 and 1000 ppm• Above 100 ppm (mg/L)First solution between 100 and 1000ppmSecond solution above 1000 ppmFurther information can be found in the data sheets in the download area of the store Manufacturer article number: 3200986784 (300-NO3-C)
