Hamilton Bonaduz wanted to update their range of pH electrode sensors with a distinct and unifying design, while at the same time improve their functionality and ergonomics. The new design utilises a set of modular components that serves to manage the range of over 25 refillable and non-refillable electrodes. A unique feature is the combined “filler-cap” and “O-ring” seal that reduces the number of parts and at the same time creates a visible platform for the product’s branding. The asymmetrical profile of the connector head facilitates handling, reduces risk of rolling off tables and remains compatible with standard fixing clamps.
