Metal Detection System

Thermo Scientific Sentinel Multiscan

The Thermo Scientific™ Sentinel™ Multiscan Metal Detector utilizes an innovative new technology to overcome the limitation of fixed single or dual frequency metal detectors that can miss metal contaminants hidden in product signals.


Multiscan technology scans a combination of up to five userselectable frequencies from 50 to 1000 kHz. This enables users to identify contaminants that are up to 70 percent smaller in volume than previous technologies, including the Thermo Scientific APEX 500 metal detector, thus reducing the probability of an escape to near zero. It is like having five metal detectors in one.


Sentinel shows exactly what a product and various contaminants are doing, taking the guesswork out of optimizing your application.
