FAZT I4G Interrogator

The FAZT I4G optical sensing instrument is a revolutionary new breed of interrogator. Featuring 4  monitoring channels the FAZT-I4G is the company’s flagship model instrument. 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 I4G is optimized for both static and dynamic measurements.

Our family of rugged FAZ Technology interrogators is used extensively in marine, railways, roads, energy, civil, geotechnical, industrial, security, medical, and many other commercial applications. It is also the instrument of choice for Research and Development Centers that seek to achieve ultimate precision and repeatability measurements. The industrial grade design scales well in volume production.
