Optical Chemical Sensor

Fluorometrics Instruments (FMI) designs and manufactures innovative, low-cost optical chemical sensor systems and fiber optic chemical sensors.
In the FMI approach, optical fiber is used as an active intelligent medium for monitoring important parameters in life science, pharmaceutical, quality control, food and beverage, packaging, fuel industry, aerospace and a host of other applications.
Our unique approach and our innovations in manufacturing arts combine to produce a low-cost product that performs accurately and reliably for years.

Fluorometrics Instruments (FMI) is based in Tampa, Florida. The company was formed in 2012 by its current CEO, Dr. M.Shahriari. As a materials scientist, he started the research on fiber optic chemical sensors at Rutgers University as a research professor in 1986. He is one of the world’s pioneers in developing optical chemical sensors based on sol-gel technology. He is the author of more than 60 refereed scientific publications and have been issued 6 patents.

In 1999, he joined the sensors department of Ocean Optics in Florida as the director of R&D. There, he continued his work on optical chemical sensors with Mike Morris, then President of Ocean Optics. During his tenure at Ocean Optics, he successfully developed number of optical chemical sensors prodhucts (oxygen and pH), based on sol-gel technology and introduced them to the market. He left Ocean Optics in 2012 to form FMI.

Dr. Shahriari has been focusing on the development of a variety of fiber optic chemical sensors since the inception of FMI. Since the company’s inception, this work has been focused on developing and manufacturing a host of optical chemical sensors for life science and industrial applications.


FMI oxygen meter (DOPO2) can be used with various AP series sensor products, from dip probes, over replaceable caps, to needle probes to monitor dissolved oxygen in different biological environments.
