FAZT I4W Interrogator

The FAZT I4W optical sensing instrument features four (4) monitoring channels and maintains many of the excellent features of the FAZT-I4G combined with competitive pricing. Enclosed in a field deployable stainless-steel casing, the instrument provides peak detection for up to 30 Fiber Bragg Gratings (FBG) based sensors on each of its 4 channels. The instrument can be operated in full  spectrum and sensor peak  detection modes. The FAZT I4W is optimized for both static and dynamic measurements.
