We were commissioned by Berlin-based start-up Concr to design a custom case for their smart concrete sensor - the ConBox. It was quite a challange to create a product that allows easy battery-swapping while providing a very high IP protection level. The bayonet connector concept of the battery cover is very ergonomic in use - even when wearing thick gloves and offers a high level of IP protection in the field.
Here is what Concr says yout the ConBox:
"ConBox is a multi-point multi parameter measuring device compatible with ConcR Sensors and optimised for the construction industry. With ConcR's innovative monitoring solution, you can optimise your construction process, minimise material waste, reduce costs and deliver superior, long-lasting structures to your clients."
