Unique: optical fiber output for an external in situ contactless probe

The AMERIGO™ is an innovative analyzer for the characterization of nanoparticle suspensions combining into the SAME instrument for Particle Size and Zeta Potential measurements

It is based on state of the art versions of Dynamic Light Scattering (DLS) and Laser Doppler Electrophoresis (LDE) techniques offering high resolution, accurate and rapid measurement.

“not bring your sample to the measurement, but bring the measurement to your process!”
