FS42PI Portable BraggMETER: Optical Interrogator with Embedded Software

FS42PI Portable BraggMETER  is a high-end instrument designed to measure Fiber Bragg Grating (FBG) sensors, being most suited for supporting installations on field or for short measurement tasks as seen on laboratory applications.

It runs on batteries or plugged to an external power source and is supplied with an easily removable bag for protection and transport. This is a unique and unparalleled solution that allows accurate measurements of FBG on field without the need for external power supply or PC and that is easy to carry.

The dedicated embedded software and touch screen interface provide an easy and effective way to control the unit without any further devices. It is also possible to control the unit remotely via the Ethernet port by using SCPI commands or stream measurement data in real time.
