COMPACT. EASY. FAST
The Sciospec EIT16 is Sciospec’s standard EIT system. It’s a very compact yet powerful instrument with 16 channels. With its outstanding performance the EIT16 has become one of the most popular EIT systems for research and industry.
With its performance and the countless customization opportunities it is put to use in leading research institutes paving the way for new applications of impedance tomography.
You want EIT on chip based sensors? We've got you covered!
We have a lot of experience with chip based sensors for biosensing using electrochemical and impedance analysis. EIT offers some very promising possibilities in that application domain as well, so we went ahead and created a simple way to work on chip based sensors with our EIT instruments – the EIT slide chip adapters.
Whether you want to design your own sensor from scratch or want to use something off the shelf, it is easy to make it fit with our slide chip system through simple and affordable carrier boards. We are happy to help you with your sensor application development – just contact us.
