It ensures precise and reproducible measurement results in a wide range of applications – from environmental analysis to industrial process control. Product benefits at a glance: Precise calibration: Consistent conductivity value with an accuracy of ±1% at 25°C – ideal for precise applications. Certificate of analysis included: Each 500 ml bottle is supplied free of charge with a certificate confirming the quality and accuracy of the solution. Safe handling: The innovative hygienic cap reliably protects the solution from contamination. Easy dosing: Squeezing the bottle dispenses the required amount of solution into the upper section – ideal for direct calibration without additional accessories. 500 ml capacity: Ideal for regular use in laboratories, businesses and educational institutions. What is a conductivity calibration solution of 84 μS/cm ± 1 % (25 °C) used for? A conductivity calibration solution of 84 μS/cm ± 1 % (25 °C) is used for the calibration and functional testing of conductivity meters in the very low measurement range. It serves as a reference solution with a precisely defined conductivity, ensuring that measuring instruments display accurate values even with solutions of very low conductivity. Typical areas of application include: monitoring of ultrapure water or deionised water, monitoring of reverse osmosis systems, laboratory applications with highly diluted solutions, quality control in sensitive production processes, and the pharmaceutical and food industries. This calibration solution ensures that measuring instruments operate reliably and in accordance with standards in the low-conductivity range. What do the specifications 84 μS/cm, ±1% and 25 °C refer to? 84 μS/cm This is the nominal value of the solution’s electrical conductivity. μS/cm stands for microsiemens per centimetre and is the unit of conductivity. The solution therefore has a defined conductivity of 84 μS/cm. ± 1 % This is the tolerance or accuracy of the specified value. The actual conductivity is at most 1 % above or below 84 μS/cm. This means it lies within a very narrow range around this target value. (25 °C) This value indicates the reference temperature. Conductivity is highly temperature-dependent and increases as the temperature rises. The value of 84 μS/cm therefore applies precisely at 25 °C. At other temperatures, the measuring instrument must perform temperature compensation. At 25 °C, the solution has a precisely defined conductivity of 84 μS/cm with a maximum deviation of ± 1 % and is used for the precise calibration of low-range conductivity meters. What is an 84 μS/cm, ±1% conductivity calibration used for? A conductivity calibration solution of 84 μS/cm ±1% is used when measuring instruments need to be precisely adjusted or checked in the low conductivity range. The value of 84 μS/cm falls within the range of very low-mineralised water. It is particularly suitable for measuring: ultrapure water or deionised water, permeate from reverse osmosis systems, slightly ionised drinking water and highly diluted solutions in the laboratory. Instruments are only truly accurate within the range in which they have been calibrated. So, if you want to measure low conductivities, you need a calibration solution with a correspondingly low reference value. The specification of ± 1 % ensures that the calibration is very accurate and the measurement uncertainty remains low. This is important for quality control, regulatory requirements or sensitive processes. 84 μS/cm is used when you want to ensure that a conductivity meter operates reliably and accurately in the low conductivity range.
