TEI, founded in 1968, is an innovative company developing new instruments under the motto "opening up the future of photonics and electronics". We believe that precision instruments are essential for manufacturing quality products. TEI successfully developed the world’s most advanced ultra-high sensitive photo-counting technique in 1976 under a Government supported contract "Analytical Instrument for Evaluating the Degradation of Oil using Optoelectronics"

From their base in Miyagi, Japan, almost 500 instruments have been supplied to companies concerned with the stability of materials to oxidative degradation, and to researchers concerned with the sensitive detection of peroxides in food or biomaterials, or the estimation of antioxidant ability.

Especially polymer & plastic processors looking to improve product quality, determine the cause of defects, or optimize all stages of their moulding processes, are increasingly making use of chemiluminescence as an invaluable monitoring tool. A key merit of TEI’s ultra-sensitive instrument is its ability to detect the very early stages of degradation.
