FS42PI Portable BraggMETER: Compact Optical Interrogator with Embedded Software

The most effective way of supporting the installation of Fiber Bragg Grating (FBG) sensors on field or for short measurement tasks on laboratory applications.

The FS42PI Portable BraggMETER 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.

Its 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  and stream data in real time via the Ethernet port using SCPI commands.
