Description
Conductivity test solution 12,88 mS is a ready-to-use laboratory standard for checking and verifying conductivity meters and sensors. The defined value of 12,88 mS supports routine instrument control in analytical, process and quality laboratories that rely on aqueous conductivity measurements. Supplied in a 500 ml pack, the solution is referenced to 25 °C, matching common instrument calibration conditions and helping operators compare readings under consistent thermal reference. Each unit is provided with a factory test certificate according to EN 10204-2.3, giving documented batch information for internal quality systems and audit trails. This Winlab ® LF test solution from manufacturer Windaus fits everyday workflows where handheld or benchtop conductivity instruments must be checked before measurement series, after electrode maintenance, or as part of scheduled equipment control. The liquid format allows simple transfer into calibration vessels or direct probe immersion following the meter manufacturer’s procedure. Regular use of a fixed conductivity test solution helps laboratories confirm sensor response, detect drift early and keep conductivity data comparable across shifts and instruments without interrupting routine analytical work.
