Breaking Down the Features of WTW Cond Cell Ac Con-modul-20 401063

Specifications

The WTW Cond Cell Ac Con-modul-20 401063 is defined by its robust specifications, designed for demanding laboratory applications. This conductivity cell module is engineered with a 4-electrode cell constant of 0.20 cm⁻¹, a critical specification that dictates its measurement range and accuracy for specific types of solutions. The cell material is constructed from durable graphite electrodes, known for their chemical resistance and consistent conductivity, paired with a robust polymer housing designed to withstand laboratory environments. This particular unit is categorized as EQUIP PARTS AND ACCESSORIES ONLY, with the supplier number being 401063.

The 0.20 cm⁻¹ cell constant makes it ideal for measuring solutions with higher conductivity ranges, such as wastewater or industrial process water, as well as moderately concentrated electrolyte solutions. In plain language, this means it’s optimized for a sweet spot of conductivity, providing excellent accuracy where less sensitive cells might be overwhelmed or more sensitive ones might struggle to deliver reliable results. Compared to standard 1.0 cm⁻¹ cells, this lower constant allows for accurate readings in more conductive media without the signal becoming saturated. The graphite electrodes are a key advantage; they are less prone to polarization effects than platinum electrodes in certain conditions and offer good longevity.
