The manikin and sensor are sold separately. However, if purchased through the Public Procurement Marketplace, the software and sensor come as a set. Please contact us with your required configuration, and we will provide a customized quote.

There’s no need to buy a new manikin — the AOK sensor can be installed on your existing one. If you're unsure whether your manikin is compatible, feel free to contact us.
